Ok, I have a Flowmaster 2-chamber cat back from my 91 GT (has Cobra bumper so this is the Cobra, LX cat back). The system has about 1k on it and still has flowmaster stickers on tail pipes. I know I am going against the norm but I hate the sound of flowmasters on small blocks. I will trade this kit for somthing else. e.g. edelbrock, hooker, magnaflow, spin teck, what ever. Let me know if any one wants this. It will fit 87-93 LX, 93 Cobra, 79-86 Gt.
