LoudMouth Modular Exhaust & Blackwing Cold-Air Induction

SLP

SLP builds bolt-on exhaust and intake hardware for American V8 platforms. What we carry covers LoudMouth, LoudMouth II and PowerFlo cat-back and axle-back exhaust systems, bullet-type mufflers and resonators, PowerFlo-X crossover pipes, high-flow catalytic converters, dual exhaust tip assemblies, Blackwing cold-air induction packages, high-flow air-box lids, replacement air filters and a filter cleaning kit. The LoudMouth systems are modular, so the resonators and mufflers can be swapped to change the volume and the character of the exhaust without replacing the system. Tubing is mandrel-bent stainless steel and the tips are hand-polished. Applications include the Chevrolet Camaro, Corvette, Silverado, Tahoe, Suburban and Avalanche, Pontiac Firebird, Dodge Challenger, Charger and Magnum, Chrysler 300, Ford Mustang, GMC Sierra and Yukon and Cadillac Escalade. Match the model year, the engine and the part number to the fitment list on each product page before you order.
