Octavia III Exhaust Thread

[99Reza]

I thought I will share what I've managed to dig up in the past few weeks regarding exhaust system for our wonderful cars (not just RS model).

Active-Sound - RS TDI Only. Must have Soundaktor - 1,159 Euro
Retrofit Kit Active Sound Exhaust | Skoda Octavia RS TDI- (http://shop.cetecarcoding.de/en/skoda/octavia-5e/retrofit-kit-active-sound-exhaust-skoda-octavia-rs-tdi)
Skoda Octavia 5E RS TDI 2.0 TDI 184 HP + Active Sound Exhaust System (Sound Aktuator) - YouTube (http://www.youtube.com/watch?v=OqopLwEnLUA) - Video
Cost as much as proper exhaust system, however from my understanding it tinker with the SoundAktor instead, doesn't seem to touch the physical exhaust. Sounded quite mean :)

Bull X - RS TSI Only - 999 Euro - German Based - 3 inch system

Website has excellent video and picture of the complete exhaust system. Good for reference. The video on the website is for manual, hence lack of DSG fart

Fox Exhaust - Most model, price vary - German Based - 2.5 inch

Miltek - Price not released - RS TSI and TDI Only - 3 inch version
From Briskoda brief review (Aussie driver), he mentioned tone change is very minimum if any. He paid just under AUD2k i think.
http://www.youtube.com/watch?v=FsbupfSTQw8 - Video - Suggest otherwise, quite loud and mean.

Scorpion Exhaust - Price TBA - UK based - 2.5 inch system
From Briskoda brief review, it only increase the sound marginally, similar to Sport mode to those with Soundaktor.

Sorry no video.

Supersprint - Most model available, RS model 1435 Euro (individual component price not kit) - Guessing 2.5inch, pipe doesn't look as large as BullX
http://www.supersprint.com/en/ET/prodt-5-7269-1.aspx
http://www.youtube.com/watch?v=2ifN1UHopY4 - Video
Nice sound from inside the cabin.

S-Motors - RS Only - Price tba - 3 inch version
https://www.youtube.com/watch?v=P7dYLv4J6Ck

From what i can gather, 3 inch version gives off deeper sound while 2.5 inch is more throaty. I personally prefer 2.5 inch version as it provide the right amount of pitch and the impression of urgency to complement the engine noise.

All the manufacturer with the exception of Bull X retain the same exhaust configuration ie: Central round resonator plus two muffler. BullX has opted to use a straight pipe where the central resonator normally live, they have a rather large muffler in the cavity on the rear left hand side of the vehicle instead.

If anyone has came across different system please feel free to add to the list.

i was going to recommend the apr rsc 3" system, but it looks like apr haven't developed one yet for the mk3 octavia yet, let alone the mk7 gti!.

Thats because APR is going broke and their RSC is a fake!

[Benmac]

Do you have a link to APR's business issues. Had a quick look did not find anything.

APR Deceptive Website and Marketing practices (http://audirevolution.net/forum/index.php?topic=2924.0)

[99Reza]

That's quite an eye opener...

[zei20t]

Avoid APR.

[vEnOm_oz]

That's shocking regarding their hardware. I presume their tunes are still reliable?

[Dzl_Dubba]

Shouldn't have any problems with their software.

[zei20t]

or you could save money and go elsewhere for similar performance...........

[99Reza]

Has anyone had any experience with Jetex Exhaust? I believe their muffler is made by Simons in Sweden.

hmmm......got me worried now!!

I've been looking at them for some time for my MkII. They supply quite a few in the uk. I checked their website just the other day when this thread was started but they didn't seem to do the Mkiii yet?

[99Reza]

Yeah no system for mk3 yet. They have one for gti mk7 though. Perhaps not far away.

I was looking at their universal muffler range and got an idea of putting few items together to make into a system, can be a cost effective alternative, around 600 bucks including shipping. Its a gamble though on how they will turn out.

[KWICKS]

GO(away)APR! Terrible. Brilliant internet stalking though.

[cbay]

How about VARDesign / Viezu? Supposedly Australian made exhausts?

[99Reza]

I doubt that they have a system for mk3 octavia. Do you know who their manufacturer is?

[99Reza]

Never mind, quick google search reveal their partner is HPX Australia. I'll shoot them an email to see if they are interested on making a system.

[cbay]

Sorry 99reza I wasn't able to get you direct information when I posted, I just remembered seeing something on Facebook about Viezu tuning and their exhaust manufacturer.


I just read some of that stuff about APR, its terrible - are Australian-installed APR exhausts imported from the US?

Unfortunately :(

I had to wait a few weeks for my full "rsc" exhaust to come in from the states!!

I should've just stuck with the downpipe.

[Lucas_R]

Havent they gone out of business in Australia? Many of their previous resellers are no longer dealing with them, including Greg (Carformance) and Transporter.

[cbay]

Ah no idea, looks like it may just be a last ditch attempt in social media. LucasR is DNA tuning still around? I have been looking at alternative tuners and remember you had positive things to say about DNA. Don't suppose they have a hardware partner?

Yes - DNA are still in Melbourne, i had my GTI tuned about 6 months ago by John at DNA.

No hardware though, they only do tuning.

[Dzl_Dubba]

Got quoted $1650 and $2200 for a Milltek catback for the RS. At that price i may go custom or just a resonator delete.

[zei20t]

ouch for a catback?? horrible pricing. go custom

[Dzl_Dubba]

ouch for a catback?? horrible pricing. go custom
Yep. Australian dealer. UK pricing in line with it too, though i suspect shipping adds alot to that price.

[99Reza]

That price seems to be the norm for complete cat back system for RS. Bull-X and Fox system is similarly priced.

The resonator delete is great for what it cost, but there is brief resonance at around 3k rpm with 3/4 throttle or thereabout, more noticeable during warmer weather. I've done few thousand km with it, it has improved considerably but it's still there, i think it will be there for good. Not sure if it has something to do with the workmanship or just the character of the motor itself.

Perhaps experiment with Mufflers delete instead :D

I'm looking at piecing together Simons/Jetex component. One resonator + 2 muffler with shipping from UK is just under $600 bucks. I will most likely going to keep stock pipe if going this route. From reading around the net, Simons muffler is probably one of the quietest performance muffler out there.

[Dzl_Dubba]

I may just remove the large resonator and put in place a small hotdog one. Though I want to see what the car sounds like with an after-market DP first. It may produce enough sound for my liking. I'm just itching for more exhaust note, that's one thing i'm not happy with on the RS.

[99Reza]

I was thinking about putting small resonator to get rid of the resonance. More cost-efficient. I'm pretty sure the OEM muffler is straight through design.

As a sidenote, the resonator on Gti mk7 look exactly the same as ours from the outside. Looking inside there is one major difference, ours is straight pipe with perforation all the way whereas the Gti one is pretty much solid pipe with oval hole in the centre. GTI has deeper exhaust tone compare to ours.

[VRS162]

I have been reading this thread for awhile Re exhaust for my upcoming VRS TSI. I have used my current car as a guinea pig (2012 MK6 GTI manual) I like 99Reza did a resonator delete to see what effect it would have, the GTI sounded much better on full throttle and a bit deeper and tougher at idle but had the same 3000rpm harsh zone on part throttle. Having today just fitted a small hotdog style resy the car is transformed. Volume has only decreased slightly but the harshness/resonance has gone. After this experience my plan is to maintain the std piping but replace the rear mufflers with a quality smaller set of rear mufflers and tune the sound with a straight through resy. The great thing with the resy is if you need to change it to either gain or increase volume you are only talking about $150.
All up I think a custom setup shouldn't cost more than $600-700 retaining the std piping. Then when you sell it you can always reinstall the std setup for a small cost. Just my two cents worth. As has been said before the RS just needs a little more beef to the sound to really give the car the edge it deserves, then turn down the sound gen a bit.

I'm planning on using Hitech mufflers as I had one of their full cat back systems on my R53 Cooper S which sounded awesome with plenty of pop and farts on the over run but no droning on the highway. I am based in Melbourne so I would buy the mufflers of HItech and get my local guy to do the fitting.

[99Reza]

Scott, thanks for sharing your experience and your thought. That's awesome and exactly what we need to hear.

What dimension is the resonator that you have installed on your current car? Any particular brand?

Would be very interested to hear how Hitech muffler sounds on our car (a plus for being a local manufacturer too), might have to put a hold on my muffler project until you have finished with yours :)

Quick update: Installed 18 inch long bullet/hot-dog style resonator the other day to see if there's any changes. The sound from inside the car is very close to stock with slight growl at low rpm. The harsh note previously experienced is now replaced with subtle deep bassy tone. The DSG fart is still there but very2 subdued. I have yet to push the car with the resi on, so can't give comment on the high rpm/WOT sound, it will probably lose the awesomeness at high rpm.

I found the 18 inch resonator kill too much noise for my liking, especially straight from no resonator. My main goal was to remove the dreaded harsh note thus choosing the 18inch, turns out it was too effective on doing that. For those coming from OEM setup (well, we all are initially), the noise increase from the 18inch resi will probably be enough for most people.

If I were to do it all over again, I would replaced the stock resonator with a 12inch or possibly smaller resonator and call it a day, the stock exhaust has actually a nice character already.

The cost of the resi was $50 bucks and cost the same for installation, took only half and hour to fit, it's a reasonably cheap and quick mod. This is a glasspack resi, eventually the packing will burn out and need replacement, those are the only type available from my exhaust place. A longer lasting steelpack or ceramicpack can be sourced reasonably cheap from ebay I think.

[Fireside]

Nice update Reza! I'll definitely give the 12" resonator a go. I might couple it with a sports cat setup later down the track too.
What diameter are the OEM pipes? I think I'm going to keep it as standard and not go up to 3" pipes on my Mk3.

[99Reza]

The standard pipe is 2.25" in diameter.

I've been eyeing Jetex component for a while, I might give those a go later down the track. Hopefully our dollar is stronger too :D.

[Fireside]

Cheers thanks!

Yeah I started having probs with the full bore 3" Miltech, not much back pressure meant every now and then I'd stall at idol (on a DSG) so I doubt I'll go past 2.5" system.

[99Reza]

Oh wow really? even with DSG? I didn't realise changing the pipe diameter can have that effect.

I do notice that since putting the 18inch resi on the exhaust the car feels stronger than just with straight pipe. Maybe it's just in my head. Perhaps the exhaust noise level is now more balance with the engine noise and alter my perception regarding the car performance.

[zei20t]

backpressure? the turbo is the back pressure, you may have had other issues.

youll probably get better results (tiny) with a 2.75" cat-back. the exhaust has cooled and you want velocity to get it out faster. 3" probably wouldn't be as effective, but to the average joe, youd never notice.

[99Reza]

I'm actually interested on what can cause the stalling issue.

I'm experiencing something similar (not stalling, yet) eversince I picked the car up. After cold start the engine runs a bit rough and whenever I stab the throttle and let it go quickly the rpm will drop below the idling rpm and stutter lightly, quite apparent at night as the interior light flickers in sync with the stuttering. The roughness and stuttering tend to dissapear after the engine has fully warmed up and whenever the aircon is running.
Mentioned this to the service centre and what they did is just re-flash the ecu, but it's still there.

[99Reza]

Made some recording earlier today to give an idea of what the sound is like.

Skoda OEM Exhaust with Aftermarket Resonator - YouTube (http://youtu.be/NOuORhYooYk)

The resi has gotten slightly louder, I'm liking it. Sound very sporty when driving the car spiritedly.

I don't know 100% that it was the pipe size that caused the stalling, but it was defiantly the Miltech 3" exhaust coupled with the setup that caused these problems.
Blufrog had an almost identical setup to me but with a 2.75" and he never had an issue (neither has anyone else that I know of)...

But I'd be interested to know if anyone has had probs with the 3" exhausts?

I was also told by the installers that it was almost certainly to do with pressure against the sensors or something (the tune should have been cancelling it out).

But now that the exhaust is off, it's gone from stalling almost once a week, to not at all!
Nothing else has changed other than the suspension removal.

So you can see why I'd be a bit hesitant to go with the same setup as last time.


On another note, I'm looking at the APR turbo Muffler Delete tho... Sounds nice, throaty! Couple that with a hotdoggy and we'll be in business!
Anyone know if it adds killerwasps? Must be better flow at least?

[Dzl_Dubba]

Probably nothing significant but more noise definitely.

[99Reza]

That turbo muffler delete mod looks interesting, not that expensive either. I'm curious to hear how it will sound with non-OEM exhaust setup.

[mazstar1980]

I've started looking for exhausts and noticed this thread, would a catback system cause engine or ECU problems?

[99Reza]

It shouldn't. Changing the downpipe on the other hand will require a tune or spacer for the O2 sensor.

Which catback system are you looking at?

[mazstar1980]

Which catback system are you looking at?

I've asked for quotes from Milltek dealers, Fox and I'm going to look into Bull-X.

I got a quote from Remus Aus which was $2700 excluding install - very expensive even if that is the gold standard with the remote valves, lovely noise. Super sprint looks and sounds good but again it would be about $3k.

EDIT: Fox is about $1300 but they have no dealers in Aus and shipping would be 700 Euro - they were keen to explore other methods as they wanted to have their first Skoda exhaust in Australia. Theirs is 2.5 I think and sounded good.

UPDATE: Milltek is going to be $3k installed $2.8k of which is parts - way too much, prefer the Remus at that price.

Bull-X is about $1400 delivered, I'll need to find a place to install but I think should be able to for under $2k all up.

I would prefer 2.5 but they all seem to be 3 inch - is there any issue with back pressure or losing power etc with catbacks? I've read forums saying it will only change the noise.

[Lucas_R]

The standard exhaust is 2.4" so you would want 2.75" - 3.00" if you were going to the expense of changing it for an aftermarket system.

A catback system is all about noise, there may be a very small increase in power (a few hp perhaps) but you would never notice it.

Turbocharged engines don't require back pressure in the same way that a naturally aspirated car does. You will find that 98% of aftermarket exhausts for your car will be 3" with the occasional company offering 2.5" or 2.75".
