Thanks, but I already ordered a 4" pipe from RJC. Talked to Jarredsoon and he was able to install the pipe on his TTA. He did however have to install an angle boss for clearance. I have one on my car already so it wasn't an issue. If yours doesn't need an angle boss than I think you should have some interest. Hopefully others reading this post will start inquiring.
Thanks again,
JB
