MBRP designs this cat-back exhaust kit to match the harsh demands off-roaders place on their rigs. After many dyno runs with various muffler designs, combined with real-world testing, engineers pulled 9 RWHP and 15 ft. lbs. out of the 3.8L V6 JK. The unique chambered design of the muffler provides a pleasingly rich rumble at idle that builds to a civilized growl at driving speeds and a throaty roar when you push the throttle down. Unlike fiber packed straight through mufflers, this muffler's chambered design can handle getting wet.

For this special off-road system, MBRP pulled the muffler forward to provide maximum clearance. They designed a heat shield and charcoal canister relocate kit to make sure everything remains safe and secure. This system is built out of heavy 16 gauge steel for long lasting durability!

*This exhaust system will ONLY fit 2007-2011 3.8L 4-Door Wrangler Unlimited models.

Performance and sound are generally the two key factors in putting an exhaust on your Jeep Wrangler. While many brands offer one or the other, MBRP offers both in their extensive selection of exhaust systems and exhaust parts.
