ProFabrication Ultra Lightweight racing mufflers are made of thin gauge 304 stainless steel with TIG-welded construction. Our mufflers produce the highest performance at the lightest weight with outstanding durability. Dyno tests prove the use of freshly packed mufflers show no detriment to horsepower when compared to un-muffled systems. Each muffler is easily disassembled for renewal of cartridge materials. We offer several options for packing material and repack kits. With a “floating core”, our mufflers allow for clamp to and rigid mounting of the outlet pipe without risk of core damage.
Our mufflers are NOT street mufflers adapted for racing use, they are hand-built by our expert racing fabricators.
