bought the the duals for 6.7 dodge. very dissapointed with results. it sounds ok but clamps dont work well, driver side rear rubs against shock and rattles. what a waste of time and not to mention money. my friend owns the same truck only he went the the banks system. now thats an exhaust. oh and the another thing MBRP better get your act together

First off - I DO NOT RECOMMEND THIS PRODUCT. I had my local Dodge dealer install this system on my BRAND NEW 3500, by recommendation of the parts guy ... should've done my research. The sound is so, so ... the left pipe rubs against the left rear shock housing and the "stainless steel" used for the tips is about as stainless as a 4 year-olds white t-shirt at a summer barbeque! I may get the tips powder-coated black or just swap 'em for a different pair. At this point, too much of a headache to go through the hassles of returning but in a year or so - I'm going to swap the whole system. This time however ... I'm doing my research.

it looks great in the box but the is not enough room between the pipes and the gooseneck frame and it rattles at idle!!!!!!

purchased bmrp cool duals 08 dodge 2500 exaust clamps does not hold securely,hangers to weak,welded pipes to hold securely in place,right side pipe longer than left,tips does not work out evenly,left tailpipe under load was no clearance between pipe and driverside shock,rubbing together,called bmrp about problem,since pipes were welded,they say system was altered,they "would not correct the problem" have bought three systems from them,pissed off, no more of my business nor recommend to anyone to purchase a bmrp product!!!

the sound and looks are great but the install is a pain and it still does not fit right .. i have to keep moving the pipes because they all ways start to rub and know have rubbed a hole in the driver shock.. not to happy
