The Xlerator 3" Stainless Steel Muffler gives off-road builders a compact exhaust solution with a controlled sound at idle and a stronger performance tone when the engine is under load. Its 14" body and 3" inlet/outlet configuration make it well suited for custom exhaust systems where chassis space is limited and excessive exhaust noise can make a long day on the trail miserable. This is the style of muffler we use at Wide Open Design when we want an off-road vehicle to sound good without being unnecessarily loud all the time. Stainless steel construction provides durability for trail and off-road environments, while the compact package works well with LS-powered rock crawlers, trail rigs, tube chassis buggies, and other custom performance builds.

Common Applications: Rock Crawlers Rock Bouncers Trail Rigs Tube Chassis Buggies Custom Jeeps and 4x4s LS-Powered Off-Road Builds Custom 3" Exhaust Systems Fitment Notes: Designed for custom 3" exhaust systems. Requires fabrication and welding for installation. Verify available chassis space before installation. Plan exhaust routing around suspension travel, driveshafts, skid plates, floor panels, and other chassis components. Allow adequate clearance around the muffler and exhaust tubing for heat management. FAQ Why does muffler choice matter on an off-road vehicle? An off-road exhaust has to do more than control sound. Rock crawlers and trail rigs can spend hours operating at low vehicle speeds with the engine under load, so excessive exhaust noise quickly becomes tiring for the driver and passengers. A properly selected muffler keeps the vehicle more comfortable at idle and lower RPM while still allowing the engine to develop a strong exhaust note under throttle. Why does Wide Open Design use this style of muffler? We like this muffler for builds where we want a performance exhaust without making the vehicle unnecessarily loud during normal trail use. The compact body also makes it easier to package into custom chassis and tight exhaust layouts where a larger conventional muffler may be difficult to fit. Is this muffler a good choice for an LS-powered rock crawler? Yes. The 3" configuration works well in many custom LS exhaust systems and is a practical option for rock crawlers, trail rigs, and tube chassis vehicles where packaging, durability, and manageable sound are priorities. Exhaust size should still be matched to engine output and the overall exhaust system. What should I consider when mounting a muffler in a tube chassis? Check driveshaft movement, suspension travel, skid plates, floor panels, fuel and brake lines, wiring, and service access before finalizing the muffler location. Leave enough clearance for exhaust heat and make sure the system is properly supported so vibration and chassis movement are not transferred directly into the muffler. Does this Xlerator muffler require fabrication? Yes. This is a universal performance muffler intended for custom exhaust systems. Welding and fabrication are typically required to position the muffler correctly and connect it to the rest of the exhaust system.
