Tiguan Modifications

[Tigger162]

Thought I start a thread which will be dedicated to modding your Tiguan. Performance, Exhaust, Handling and styling plus any associated modification chit chat. I know there are a lot of you guys out there so let's keep it in the one place. Looking forward to what others come up with.

[Tigger162]

I'll start off with a question regarding modification's done during warranty period. What's allowable and not allowable and are there ways around it. Exhaust will be a touchy one as a performance exhaust could not only void your warranty but insurance as well.

[tigger73]

A cat-back exhaust in itself won't void your warranty - it'll just make the car noisier.

Though it will raise a flag with VW dealer that there may be more done to the car than just an exhaust (i.e. tune, etc).

Anything that gets added after it leaves the dealership will have it's own warranty/guarantee from whoever manufactured the aftermarket part. If you have a problem with an aftermarket exhaust then you go back to the company that supplied it.

Looking forward to seeing what people do to their gen2 Tigs.

Yeah. The cat back is after the catalytic converter and comes with its own warranty as the VW warranty on exhaust will be void...

What is a good cat back to get? I am sydney based

I'm pretty sure you'd have to go to an exhaust shop and get something custom built as I'm almost certain there are no exhausts for the gen2 Tiguan yet. I've done this a couple of times with my last 2 cars and you generally don't pay any more than an aftermarket exhaust. The good thing with a custom set-up is that you can work with the shop to get the sound you're looking for.

Yeah done that a few times. Sometimes I ended up with unique sound from my car vs. others.

What if you had a full performance exhaust system fitted and then you had a issue with the engine. Would the dealer walk away cause you have modified it? I heard once that they need to prove that was a contributing factor that caused the failure but then maybe they don't have to I don't know. I just don't want to do something that's going to ruin me during the warranty period.

[tigger73]

The only point of putting on a full turbo-back exhaust is if you tune it. Otherwise just do the cat-back for the extra noise and DSG farts.

If you change the down-pipe section, you will need to modify the ECU/tune it so that you don't throw a CEL (Check Engine Light) from the O2 sensor. Any change in the downpipe will upset the sensor, however most stage 2 tunes will mask this out so it doesn't cause a problem.

I think once your vehicle is modified it will be a bit of a flag to the dealer. However if you haven't tuned it and just put some bolt-on stuff on, you should be fine.

[Delewin]

I'm going to play safe. Just wait until the warrantee period is up. 3 years will pass quicker than you realise. Just treat the first 3 yrs as an extended running in period. [emoji24]

Here's my view on this topic. Either way you do it you won't have a warranty after you put a tune on... so you may as well do it sooner and enjoy it :)

From stock (162kW) to Stage 1 (235kW) is a decent 45% (70kW) increase in output.

I've driven a stock Mk7 Golf R and a stage 1tuned one and the difference is like chalk and cheese. The stock car feels a bit dead/lifeless in comparison to the stage 1 tuned car.

[Delewin]

Tigger73
I think a simple ECU stage 1 remap will not get you 235 Kw. I thought the Golf R has a bigger turbo than the Tiguan and therefore the Tiguan would only expect around 185 Kw to 195Kw.

I stand corrected. Wow. I have seen Australian suppliers quoting 185 to 195 with no other modifications. That is really impressive. I would assume you would have to run 98 octane to reach those figures.

190kW was the specs for stage 1 on a Gen1 Tig.

I'm sure there's someone in Sydney that can tune your car. Whether it's Revo, APR, Custom Code, etc they should end up around the same output.

The big advantage with a tuned Tig over a GTI is the traction of AWD. So you can actually use the 235kW whereas the GTI just ends up spinning the front tyres and struggling for grip.

[Gladbach]

Curious about the extra strain on the diff, dsg etc. Are these components rated for the amount of torque/power?

The same dsg & diff are used in the twin turbo diesel which has 500 nm of torque.

[tigger73]

DSG in the Tiguan is high torque unit and is nominally rated to 500Nm (DQ500), however I think it can handle more like 600Nm. It will be able to handle a tune no problems.

From sounds of things the launch control in the gen2 Tig is a little more refined, so is likely a little less stressful.

Yeah, that makes sense.

[Delewin]

But I think how the torque is delivered has an impact on the life of the day and dif. The diesel would deliver it much more smoothly that the petrol engine.

Correct. I think the weak link in the 1st gen Tiguan was the transfer case to power the rear tailshaft: http://www.vwwatercooled.com.au/forums/f97/ramees-tiguan-build-thread-155kw-dsg-87535-11.html#post1012992

There's a couple of people that had to replace these when they were launching and with higher power outputs. I'm not sure if the transfer case has been beefed up in the Gen2 Tig or not.

Yes, 100% true. I'd still drive it for 10,000 km or so to make sure nothing is faulty out of the box then slap the tune on.

Likewise I'd probably wait until after the 1st service and then if everything was good look at doing something then.

If the first service is like it was on my Audi then it's basically an oil change. No one will look at anything, certainly not at a VW dealer. You'd be better off to go to your chosen tuner, get them to look the car over and, if they don't find any issues, go ahead with the tune. Or get them to do their first service, an inspection and then the tune in one go ;-)

Just wondering where you got your exhausts done in Adelaide Tigger? I'd like a louder exhaust sound + pops/crackles but not sure if I would need to go Res delete or just cat-back exhaust.

I've used Exhaust Technology on Goodwood Rd (near the underpass) in the past. I've also heard good things about AAA as well but haven't used them personally.

The rear muffler will be the biggest noise suppressor as its so freaking huge.

Would need a custom made replacement.

Currently working with Rob Bliss Exhaust in Queensland to get a decent exhaust system together. Scorpion Downpipe w/ Mid pipe (deletes resonator) to a custom side inlet twin outlet 3in System. This is muffler is very popular for them with GTIs and Rs. This set up has a bit of Drone and Booming, going to try some inserts to get that under control. They're pretty confident that these inserts will be enough and no resonator will be need. Will give on update on Friday.http://www.vwwatercooled.com.au/forums/images/imported/2018/08/dd235ebc061bde8c5f2a2e7dd1723b4d-1.jpg

He explain, "They are like a reverse cone which we put into the end of the muffler and they basically create a helmholtz chamber in the muffler. Basically it’s designed to bounce sound frequency’s against each other to reduce drone".

Hi Twyat1
Looks good. Is it a scorpion muffler also? Would be awesome to get a sound clip (although I know it probably doesn’t do it justice) so for those contemplating getting a muffler they know what they’re in for.

Yes it's a powerflow muffler. Inserts have helped quite a bit but I think it may need a resonator still for my liking. WOT Sounds amazing.

Costs was 2-3k?

Seems very high considering that an off the shelf downpipe is just over 1k which is esentially 3/4 of the exhaust including high flow cat, the rest of the exhaust is only a small section with muffler. Powerflow mufflers costs I saw were under $200.

Perhaps a Golf R or an S3 muffler might fit better given that those are AWD, keep us posted as there should be quite a few second hand mufflers around. If the mounting points are similar you could drill out the fake exhaust and poke the exhaust tips through.

[Hole46]

Has anyone tried removing the fake exhausts?

I have seen it done.

2 things to keep in mind is that the plastic on the rear bumper may not be suitable for higher temps (may be a softer plastic which has a lower melting point). Second is that if you have rear park sensors they are quite close so you don't want to melt the wiring.

So if you're going to do it make sure whoever is looking at it addresses these couple of issues so you don't end up with a big mess (and expensive repair bill).

[Dutch77]

^ very valid points.

There are example pics in the Tiguan Exhaust thread, I haven't read so unsure if they're mock-ups or genuine though.
