I'd like to see headers for T1 like the T4 headers, where the collector is perpendicular to the center-line of the vehicle.
I've never liked having the exhaust sticking waaaaayyy out the back with a big honking turbo muffler hanging out even further.
Especially after having someone vandalize my exhaust one night by standing on the dual QP muffler tips and bending the whole thing down!
Can't find a pic right now, but I think it really cleans up the whole look of the car when you can hide the exhaust (can you say sleeper?).
