Important Fitment Note
If your car is still equipped with OEM engine/transmission/dogbone mounts fitment issues may arise. As these vehicles age, OEM mounts tend to sag due to the weight of the engine and transmission hanging from the rubber mounts. This may cause the downpipe to make contact with the rear subframe. It is HIGHLY recommended that you replace your engine and transmission mounts to avoid fitment issues and potential rattles. Replacing the dogbone mount is a good start, but it will not always fix the issue if the motor is hanging too low.
TT225 downpipes now feature an adjustable turbo flange to help with fitment issues related to worn mounts. The adjustment may allow subframe clearance unless the mounts are too worn. Note that some aftermarket motor mounts may slightly change the engine location which could affect exhaust alignment.
This turbo-back is known to fit the following vehicles:
- Professional installation is highly recommended.
- 2000-2006 Audi TT 225 1.8T Quattro
Polyurethane transmission mount inserts are HIGHLY recommended for this application.

180hp TT Owners Please Note
We are aware that many 180hp FWD and 180Q owners are converting to 225 turbochargers and exhaust systems. Before purchasing any of our TT exhaust components for your conversion, please contact us to discuss your project. The internet may say "it will fit," but our experience proves otherwise. There are distinct differences between the 180FWD, 180Q and 225 stock exhaust systems that many will deny. We have proven these differences and we urge you to contact us before purchasing exhaust parts for your conversion so that we may steer you in the right direction.
