Banks Power Dual Monster Exhaust System
|Cab & Bed Configuration:||
2001-2005 GM 6.6L Duramax LB7/LLY
Banks Monster Diesel Duals 4" exhaust system offers up to a 150% improvement in airflow and slashes backpressure up to 98%! The streamlined head pipe assembly (non-cat.-converter equipped vehicles only), intermediate pipe(s) and 3-1/2" tailpipes are formed of stainless, heavy-wall tubing with constant-diameter bends to slash backpressure. The dual tailpipes have 52% more flow area than a single 4" tailpipe.
The 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. Monster muffler utilizes spun ceramic, very-high-temperature packing, more than triples stock flow, and delivers an authoritative exhaust sound. 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.
Split-dual exhaust applies to single-rear wheel applications only (they do not fit appropriately on duallys)

BAD exhaust doesn't last

Got the banks power pack 3 years ago and it has completely rusted and about to fall off and the headers after 2 years had a leak. For most of that time I lived where it didn't snow much and I washed the under the truck after every winter. The exhaust should have lasted longer hell the factory lasted longer then it.

I was note very impressed with the sound quality of the exhaust. Also once shipped to me the muffler had a dent in it and also one of my tips. Very easy to install tho.
