Exhaust System, Loud Mouth II, Rear Axle-back, Dual, Stainless Steel, Natural, Split Rear Exit, Ford, 5.0L, Kit
If you're looking for the best-flowing, meanest-sounding exhaust systems in the business, then SLP's Loud Mouth II systems are for you. Not quite as loud as the original Loudmouths, the systems' great sound comes from a pair of stainless bullet mufflers with embossed SLP logos. The engineers at SLP developed a great sound for the street without objectionable in-cabin resonance. The additional performance comes from their free-flow design and their built-in PowerFlow-X crossover system that borrows a power-building technique widely used in stock car racing. These systems feature a pair of distinctive 3.5 in., dual-wall, stainless steel tips that look great peeking out of the rear of your ride. The tips can angle downward in a traditional style, or rotate at a 90 degree angle so that they match the curving shape of your rear valance. Their modular design gives you the flexibility to change to a louder system in minutes by using a pair of bolt-in Loud Mouth resonators, if you choose.
