I guess it's just the ricer (not really) in me. I wouldn't put anything Borla, Magnaflow, etc, etc, on my cars on principle.
For the record I am against loud ass exhausts that do nothing. I understand that in turbo applications more is ALWAYS better, but after seeing and hearing it day in and day out, can't you (people in general) cap it for daily usage, and let it rip when you wanna go racing? Driving next to that junk @ 75mph on the freeway the driver is doing EVERYONE a disservice.

As an aside, if someone offered a "slightly" larger diameter exhaust with mandrel bends and good, high flow, mufflers (not straight through) I would scoop it up in a heartbeat after doing all the important mods.
