;D.....drooling...thanks for the report...I've got my mind made up on the N1...I think I'm going with the Turbo XS downpipe...4.5 in!!!! I've got an email in to find out what's it's constructed of..hopefully quality stainless...I shopped around and did a lot of research. IMO, the invidia N1 is the best sounding 08 exhaust availible and is also one of the least restrictive in its design. I also went with a catless Invidia downpipe but I will tell you, going 3" catless takes the car from mellow and deep to a whole new level of pissed off angry rumble. When you delete the cat you can hear the turbine spool up VERY clearly, its nearly as loud as the exhaust is.
