Banks Power - Monster Exhaust - 07-10 Chevy/GMC 6.6L LMM, ECSB-CCLB, Single, Chrome Tip - 47784

4" stainless constant-diameter DPF-back system with unique CoolCuff design cools tailpipe temps as much or more than stock and way more than others; improves flow and cuts backpressure by nearly 57%; huge polished tip. 4" heavy-Duty stainless DPF-back Monster Exhaust system with constant-diameter intermediate pipe and tailpipe. Exclusive CoolCuff design lowers tailpipe temperatures as much or more than stock while simultaneously improving flow and cutting backpressure. The CoolCuff design is tested and refined by Banks engineers using Computational Fluid Dynamics software, then validated through extensive temperature testing in all areas: before and after the DPF, 6" out from the tip, by the spare tire, shocks, wiring, hoses, and more. First we tested our own exhaust then we tested the others. Result: Monster Exhaust measured well over a hundred degrees cooler than the competition, and cooler than stock, too! The system includes a huge 6X5" polished-stainless rolled-edge tailpipe tip, and comes with a 5-Year Limited Warranty.
