    So i bought an 87 v10 and i need to put a new exhaust on it... It needs to meet emissons standards though, which mean a cat in stock location... right now it has dual, no y pipe and 2 cats, 2 mufflers... I could go stock y pip but thats a 135 bucks and i dont like how low they hang... Then i still gotta get a cat and finish the sytem. Anyone have any ideas? best bang for the buck?

    Also any pics of an exhaust on an 87 would be nice thanks guys...

    P.s. its stock manifolds or int he future shorty headers... F going long tubes on these trucks... nothin but issues:rolleyes:

    I switched to flowmaster Y pipe with 3" single ex. thru hi flow cat and magnaflow muffler exiting behind LR tire. Much better than stock. You are better off generally with a single pipe system when under 350 hp in a sbc.

    sorry for the hijack, but do you know what headers you`ll be using?? I`m having trouble finding ones that will be a direct replacement...

    I believe he's talking about Edelbrock headers. They are direct replacement bolt-ints and i think LMC has em. :wink1:

    I had a local shop make me a Y pipe and placed it so that it tucked up nice and tight to the tranny pan but far enough away that i can still remove the tranny pan without pulling the exhaust. I also run a single 3" exhaust through a hi-flow cat and into a Gibson flow through type muffler then exit out the driver side behind the tire. You will make more torque with a single 3" exhaust than you will with a dual 2 1/4" or 2 1/2" exhaust.

    Sorry, I'll be more specific. It is a standard Flowmaster Y pipe used for multiple applications.

    i believe '87 + had 3" exhuast stock, mines an '88 and i went to the auto parts store, and bought the oem piping and just put a flowmaster super 40 on it and it has worked great. it was 3" the whole way back after the y pipe

    lets see some pics of the new truck :)

    Every set of headers ive ever seen, regardless of brand quality, price whatever has either hit the shackles, tucked too close to the motor, starter and numerous other clearance issues...Some are minor but a set of shorties will do fine:D
