is it possible to stuff a 4" dual exhaust under a 94 6.5 k2500? i would like to do it if it can be done, i just dont know what the bends in the left pipe would look like. would it have the same bends as a gasser exhaust but w/ 4" pipe? also where would i get custom bent 4" pipe? ive read that most muffler places only bend up to 3" pipe. help would be great

go to a heavy duty diesel muffler shop. they have equipment to bend the pipes for big rigs and yours is comparatively small considering. as for stuffing dual 4 inch, anything is possible at the right price. question is if there are ebayers selling 4 inch kits tailored to fit our trucks. why spend money for duals.

Your entire exhaust system is dependent on the downpipe, which for most of us is a 3" pipe. Mine goes to a cat (ok, it looks like a cat on the outside), then to a 4" exhaust pipe and muffler. Splitting the 3" downpipe won't net you a significant amount of flow increase. Yes, it can be done, but the benefits are few. A 4" exhast on these trucks is fine. If you just want 4" duals, go for it.

what i was thinkin was gettin a 4" exhaust, and then deleting the muffler and putting in a y pipe (makin it a straight pipe) and adding the left pipe for duals. how much would it be to have 4" pipe custom bent for our trucks?
