Moving Forward

If you hate the factory rear-mounted muffler on your Jeep Wrangler JK, you need to take a look at MBRP’s Off-Road Exhaust System. This bolt-on, after-cat system mounts a much smaller muffler under the center of the vehicle where it’s less likely to be damaged. The system is available in three versions; black powdercoat, aluminized steel, and T409 stainless steel, for two- and four-door JKs. (FYI, if you install the two-door version, you have to use MBRP’s Heat Shield/Charcoal Canister Relocation Kit.) An added bonus is that MBRP says this kit can improve fuel economy by 1-2 mpg and offers an increase of 9 rear-wheel horsepower and 15 lb-ft of torque.

We recently had the opportunity to watch a T409 system being installed on a JK four-door at Moab Offroad in Louisville, Kentucky. Here are the highlights of this easy install.
