    my suburban has factory dual cats so does anyone have an h-pipe, dual mufflers and dual exhaust set up on their truck. would it help at all with hp or tq numbers on a suburban, or not worth it?

    Do ya have headers? Do you have stock cats? If the answers are no and yes then adding the H pipe will most likely not help you in the noticable HP and TRQ areas. I would say you need a set of long tube headers and some high flow cats to do any good. I have shorty Pacesetter Headers Magnaflow HFC's and flowmasters on my 00 Sierra. It all sound good, but I did not realize any advantage due to the shorties. I will be feplacing them with LT's SOON. Hope this helps you, and the outher guys may more and better ideas than me.
