Monster® Exhaust
ISB PICKUP: Constant-diameter to slash backpressure and lower exhaust gas temperatures, Banks' Monster exhaust pipes bolt behind the turbocharger. The streamlined 4" turbine outlet pipe, head pipe, intermediate pipe and tailpipe are formed of stainless, heavy-wall tubing with constant-diameter bends to outflow stock and the competition. Banks replaces the factory's restrictive muffler with a polished-stainless Monster muffler, featuring a straight-through 4"-diameter flow-path with a Banks-designed expansion chamber to dissipate the annoying mid-range exhaust drone that plagues most straight-through mufflers. Muffler utilizes spun ceramic, very-high-temperature packing and delivers an authoritative—but never intrusive—exhaust sound. The huge 5" polished-stainless steel tailpipe tip sports a rolled edge. Double-walled design with 1/2" air gap keeps heat from tarnishing exterior mirror finish. Adjustable clamp for positioning on tailpipe. Extension pipe included for extended-cabs.

Tom I got the Exhaust kit and as you said it was a snap to install, fact is it took longer to remove the old one than install the new. You said it would take about two hours, I guess with the right tools it did go faster than that. It took 45 minutes to remove the old and in less than a half hour after that we were on the freeway. The power had a great increase, and I know that the mileage has also increased too. My didn't like the idea of putting the new system on, but after a few hills and me asking her how do you like the sound, much to my surprise she said "I cant tell the differences." However, she did notice how much quicker it was at attaining the speed limit. The system is just what I wanted, thanks for the help.

“We went to the source of diesel-engine performance, Gale Banks Engineering, and struck gold. Not only did it take one stop to buy and have our parts installed, but the parts worked as advertised and the results were awesome.”
