Difference between 180hp and 225hp exhaust systems
The K03 needs replacement on my 2000 180hp TT. I have an APR chip with the K04 program ready to go and have bought the 225hp injectors and exhaust manifold so that I can accomodate the K04-020 (stock 225hp TT turbo). The only thing I would need is a downpipe to match this turbo as the K03 has an integrated O2 housing into the turbine housing vs. the K04-020 which does not. Can I just purchase a downpipe that will fit a 225hp TT or does the downpipe to cat connection differ between the two cars? I know the K04-001 would bolt up without any issues, but this is what I wanted to go for.
To the point: Is the downpipe the only part that differs in the exhaust system between both models? I see guys bolting up the catback section of 225hp stock exhaust on 180hp TT's all the time, but I'm not sure about the rest of the exhaust system. Thanks in advance!

Sorry, I should've explicitly said 180hp quattro.
Just need to know if I have a K04-020 and bolt up a 225hp downpipe, will the opposite end bolt up with the stock 180hp quattro exhaust system?
