Title: Fitting 3" downpipe and decat what do I need to know??
Post by: AmaZak on September 05, 2012, 04:34:41 pm
HI guys,

Just got myself a 3inch downpipe and decat, I am running standard exhaust and I need to know if I require any special reducer etc to get this on. It is going onto a Jetta 2.0 TFSI which I believe has the same setup as the mk5 gti.

Thanks

It looks like the second pipe in the picture reduces at the end where it would meet the standard rear section so should be fine

I assume this is a decat and would therefore not pass an MOT?

Yes that would be correct.

You also need to know that you will have exhaust emissions light.

But more importantly.... They're awesome!

Yes it is! LOving the sound of the turbo spooling really makes the car sound mean! Remap tomorrow although the emissions light has not lit up, was it meant to light up immediately?
