Well as far as i know the shortest chassis with a duramax is either a short bed ext. cab or a reg cab long bed. So what Im asking is what truck should i buy an exhaust for my rcsb truck? And where are you guys shortening the exhausts to fit on your downpipes? This is going to a kbracing mp70 kit

 

Its easier just to buy a couple 4" 45* bends and piece something together. I only used 3 on mine.

 

Well next weekend is the All truck nationals in Carlisle PA, so im thinking ill probably be able to snag a exhaust for cheap and was wondering what I should get

 

I found a kit that doesnt have the hangers welded on. This allows me to put the pipes where they fit best and fab the hangers so they work with the stock 1/2 ton hangers. Frames are taller on the 3/4 tons (that the exhaust was meant for) which gives them more room, 4" gets tight on a torsion spring 1/2 ton truck right at the mid crossmember. My 99 coil sprung front will have lots of room, no cross member there. There is plenty of pipe and extra bends to make a mid pipe if you dont like the routing of the diesel mid pipe to where your down pipe comes in.
