4" stainless mandrel-bent system. Dramatically improves flow; virtually no backpressure; lowers EGTs; safely clears spare tire; throaty sound; huge polished ob-round tips.
Monster Diesel Duals 4" exhaust system flows up to 88% better than stock and virtually eliminates backpressure. The streamlined 4" turbine outlet pipe (not required with 325 hp systems), intermediate pipe(s) and 3-1/2" tailpipes are formed of stainless, heavy-wall tubing with constant-diameter bends to maximize airflow and lower exhaust gas temps. The dual tailpipes have 52% more flow area than a single 4" tailpipe.
Banks' polished-stainless Monster muffler features a straight-through 4"-diameter flow-path with an exclusive expansion chamber to dissipate the annoying mid-range exhaust drone that accompanies most straight-through mufflers. The muffler utilizes spun ceramic, very-high-temperature packing, flows up to 129% better than stock, and delivers the signature Monster sound in stereo. Now for the cool part: Banks' exclusive 6" X 5" ob-round polished-stainless angle-cut rolled-edge tailpipe tips (patent pending)! System safely clears spare tire, shocks and brake lines.

Needed muffler and tail pipe which was not available aftermarket. Dodge dealer wanted $547.00 for stock parts. Decided if I was going to have to spend that kind of money why not improve entire exhaust. Talked to a lot of people and spent 3 hours on internet before deciding on a Banks Monster stainless exhaust. I was concerned it might be too loud but ordered it anyway. WOW!!! Talk about QUALITY!! Sounds good but not too loud. I have decided any other improvements will be Banks products. You have earned a lifelong customer due to engineering and testing. THANK YOU!
P.S. Patiently waiting for air filter restriction indicator to tell me to call my new friends at BANKS!!

I just wanted to drop you guys (and gals) a letter stating how much I appreciate your products. I just spent the afternoon taking a competitor's product off my truck because it did not work as claimed and in fact made my vehicle unpleasant to drive. I have several Banks items on my truck and they all have fit perfectly, worked as claimed and have never caused me a minute of dissatisfaction. I will always buy from your company in the future for any performance product related to my vehicle. Trust me when I say I just wasted $400 to learn that I should've stuck with a brand I know and trust. Keep up the good work.
