The Jeep specialist at St. Louis' Axleboy Off-Road know how to get power from your Jeep JK Wrangler and high flow exhaust from MBRP is great way to get it. More efficient, better throttle response, throaty sound, and more ground clearance, all from one easy system.

Why Pick MBRP for Your Wrangler?

Wrangler owners expect a lot from their ride. Yet many exhaust manufacturer's figure they can simply pack the same generic muffler into their Jeep kits that they put on a Civic. At MBRP we designed our Jeep JK/TJ muffler to match the very real demands off-roaders have for their rigs. After many dyno runs with various muffler designs, combined with real world testing, we were able to pull 9 RWHP and 15ft/lbs out of the 3.8L V6. 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 our chambered design can handle getting wet.
