    My uncle (P.O) told me he had the cat gutted, but i know that's BS since there's no muffler or piping past the tranny crossmember, just the cat, and it sounds muffled as hell. A real gutted cat would sound INSANE with my set up. Practically open-headers. I want to take the cat completely off, then put a flowmaster or thrush in its place.

    I have a 94 4.3L. My manifold is cracked and want to go to headers. Are the 96 4.3L really so much different that they won't fit? Or is it just bc it's a vortec?

    Any ideas on a manifold back setup for 1995 k2500 suburban with a Tbi 454. There doesn't seem to be much out there on the market.

    I have been considering just gutting the cat and going with a 30" magnaflow 12641 dumped out behind the axle.

    Anybody come across a header-back exhaust for our trucks online? I'll be welding up a new exhaust but the thought crossed my mind to buy one.

    I really want the sound of duals for my 88 4.3l Cheyenne long bed, but am concerned with the cat and O2 issues on it. It is a TBI system, single O2 before cat. any thoughts? and no I am not gonna swap out the engine.

    There won't be any issues if you remove the cat since the sensor is before it
