Replacing the muffler on your Jeep Wrangler is a lower-cost alternative to changing out the whole exhaust system, or provides a handy repair for damaged exhausts, winning some extra torque and horsepower in the process with wide-open 2007-2018 Jeep Wrangler JK mufflers. These top quality performance mufflers, bearing such noted names as Flowmaster or Gibson, feature many different inlet/outlet configurations to match specific arrangements of exhaust tubing, including offset/offset, offset/center, offset/double, and center/center. Extreme Terrain stocks the cream of the crop when it comes to 1997-2006 Jeep Wrangler TJ mufflers, with all-welded stainless steel models making up the bulk of those available. There are also some aluminized steel examples to choose from. All of them offer an improved richer, deeper exhaust note, drone-free operation, and faster flow.
