I have a magnaflow system for the 3.4 liter V6 camaro/firebird its brand new in the box i bought it for my gfs camaro but she said i spent too much on it i just want to get rid of it so i can get some of the money back it has not been opened or touched. its a stainless steel catback set up. its slip fit so there is no welding needed, it comes with all the parts needed to install. i will sell it for 280 obo
