I have this in my 1.8t passat and it works as it should. However, I did have to modify the bend in my exhaust after this downpipe because the angle changed with this converter pipe. This pipe did not match the bend that the catalytic converter which required me to make the modification. Maybe this would be the case for you or perhaps it was unique to my situation. Otherwise, this pipe does the job and works great. The only other notable thing is the back o2 sensor port doesn't have a lot of clearance when installed.
