Banks Power - Monster® Exhaust

Too much potential power is lost when the Jeep engine labors to expel exhaust gases through a backed-up system. The Banks Monster® Exhaust keeps exhaust flowing freely all the way from the catalytic converter to the tailpipe tip. Backpressure is virtually eliminated, resulting in greater effciency, fuel economy and power you can feel. Banks Monster® Exhaust stainless steel, straight through muffler more than doubles stock flow and it's sound tested to deliver that rich, throaty growl you want, with none of that maddening drone you'll find on our competitors generic designs.

The tailpipe is construcyed of T409 grade stainless steel tubing. Hangers are welded in factory stock grommet locations. Mandrel bent for a constant diameter to eliminate backpressure caused by exhaust turbulence. Banks tailpipe tip is available with Chrome over Stainless or High-Durability Black, these tips give your Monster® Exhaust a high quality finished look.

Includes: Monster Muffler, 2.5" Tailpipe, Chrome Tip & Mounting Hardware.
