heres a couple pics of the exhaust. its all mandrel bent pipe. i am going to clean it up tomorrow and spray the welds with some HIGH temp paint.
this is a good setup and will out flow ANY 3inch catback and y-pipe.
this is the only damage to the exhaust. the only reason this happened is because the shop that hung it used screws to mount the hangers to the body. well the backed out after a month or so an got dinged by the road. the dent is small and doesnt affect the sound/performance at all. they fit really close to the body and i NEVER had any ground clearance issues.

with this exhaust, pacesetter longtubes, slp cai, 58mm tb, underdrive pullys, and 6 speed manuel my car put down 302rwhp and 335rwtq. that was also with 4.10 gears which will lower you hp level by about 5% so i was told by the dyno shop.
