    Default 1997 Gmc K1500 exhaust advice

    My name is Cody I have a 1997 Gmc Sierra K1500 V6 4x4 right now its set up comes out of the manifold and into a Y and into the cat comes out the cat into my glasspack and into they Y to make it duals. I want to make it a true duals system but im iffy about it because of just the one cat. If anybody has any advice please let me know.

    i just spoke with flowmaster about this....... but it was for a V8...
    point is, you should not do that.
    especially with a little V6
    do a stock Y-pipe from the manifolds to the cat, then step up the diameter .5" for the cat, and run that through the muffler all the way to the rear corner.
    done.
    if you do it the way you are discribing you will simply loose power and disrupt firing order exhaust flow/ back pressure out of the engine

    dont do the dual outs
    its a 6cly
    its not worth it.
    save up for a V8 cause that motor is gonna loose compression and give out driving that huge truck around.
