Tiguan Aftermarket Exhausts

[tigger73]

As requested here's a "before" video of the stock exhaust with 3" DP.



I'll hopefully get an "after" video up by next weekend.

New exhaust on - lots of noise...



Though it's quite quiet at highway/cruising speeds.

I'll get a clip up on the weekend.

Well that is a bit annoying, i thought for sure the GTI fmic should fit given it is the same 2.0TSI.
Keen to hear the exhaust clip!

OK here's the audio clip. Probably doesn't give a true indication how loud this is - system is non-resonated.



This was a cool morning and the first 60 seconds the auto-choke is active. After that it quietens down... and then a couple of revs with a pop.

Here's a photo from under the rear of the car.

Hey t73, how are you liking it driving around town? Also like to get your thoughts on what it would be like out on the highway, once you get a chance!

I got a 2nd - handie CAI i'm gonna install tomorrow & may go down the path of more exhaust mod's soon...

You can drive it quietly around town - drive it in "D" and keep the revs under 2,500rpm and it's relatively docile.

However give it a boot load and it is pretty loud.

I have done about 1,000km of highway driving and there is no drone in the exhaust. You can certainly hear the exhaust note while cruising but it isn't intrusive. There is a fair amount of noise when overtaking and going up hills it is certainly louder than stock.

I'm still waiting for it to soot up completely (1,500-2,000km) and after that it should be pretty much how it's going to be.

...though still considering getting a resonator fitted as I do use the car for business.

Just a word of caution on installing any old CAI. The ECU is pretty sensitive with air flows and aftermarket CAI's can upset them (speaking from recent experience). I changed my CAI recently from one design to another this and caused all sorts of issues. Ended up reverting back to the stock intake and this fixed things.

Oh so you are now running without the middle resonator? I thought without it would make a nasty drone.. Also any feeling of extra power with the new exhaust .. I guess improved sound will automatically add 10Kw

Yes exactly - middle resonator is gone completely (must have evaporated while I was driving). Just a pipe with a couple of bends from the cat to the muffler at the back.

No drone at cruising speeds. HM Headers are making these for Viezu Australia under the VAR Design name. They are a major exhaust manufacturer and manufacture exhausts for HSV, Walkinshaw, Elfin as well as aftermarket systems for a lot of other cars. So they know a bit about making exhausts.

I wasn't expecting any increase in power - just sounds like it goes faster now

Lol .. So you must be driving crazy fast than me or you can blame Vezu tune for making exhaust temp too high last time I checked my one was there Speaking of which did you get the new race tune yet?

Exhaust temps are fine but must have been the rough roads

Speaking of which did you get the new race tune yet?

Not yet. Race tune file is still not released

Though I am told it's something special and will be worth the wait - going for 200kW+
