Just picked my 05 monroe 4500 4x4! Already got xccelerator programmer, snow performance water/methanol injection and am now looking for someone who makes an exhaust system for these trucks. Anybody out there purchase one for their truck yet? And if so what did you pay and where did you get it?

Any help is greatly appreciated.

Make youre own. You are limited to the size of the exhaust brake, but after it you can go as big as you want. Go to the nearest truck parts dealer, look in the catalogs for a free flowing muffler and manderal bent pipe. No one makes a system for this truck, yet. Good luck.
