i was looking in summit for exhaust for my 85 iroc tpi. i found american thunder exhaust for my car but i have a few questions..is it dual (u know..the fake dual, lol) and also it lists for 86-91. wouldnt it work on my 85? maybe its not in the book but they do have it for my 85? thanx for the help guys..

 

85 have oval pipes and cats the connection to the cat is different.

 

it is a fake dual setup...its a 3" intermediate and overaxle pipe, then goes into a crossflow style muffler (80 series), than it has dual 2.5" out with 3.5" tips I believe....

not sure about why it wouldn't fit your car, but if you took it to a shop or something, I dont' see how they wouldn't be able to fab something up to make it work...just make sure they don't put a crush bent pipe in there, that will put an end to your flow...

 

well i am getting a cat for it. mine is really bad. like..i dunno if its clogged or what but the car runs like crap whens its first started after its been on for a few mins. if i hit it it rattles so...its gone... so maybe that wont matter then. the cat may have different openings that might work. ill get it 2 work somehow i guess
