does anyone know if anyone sells a universal 4" exhaust pipe kit? or maybe even a 3.5" my pipes arnt lining up so im going to have to have a custom set built. only issue is no one in town can bend over 3" so i may have to buy a kit with pre bent stuff. any ideas?

 

Duramax exhaust...either find a stock setup off Craigslist or go with an aftermarket cat back like MBRP, Magnaflow etc

 

ya i have a 3.5" dmax exhaust. my issue is the down pipe and the mid pipe. the down pipes to long and 3.5" were the turbo ext housing is 4" and the mid pipes touching the frame of the truck
