Important Notice relating to US Domestic Market Trucks & Pickups

Many US-market trucks and pickups are available in multiple cab and bed-length configurations (e.g., Single Cab, Extended Cab, Double/Crew Cab, CrewMax, 5.5ft/6.5ft/8ft beds, etc.). Exhaust system fitment can vary between these chassis versions.

Where available, we list all compatible vehicles, cab types, and bed lengths in the product description. However, depending on your exact configuration, some systems may require optional extension/mid-pipes or minor modification for correct fitment.

Because of these variations, please carefully check your cab configuration and bed length before purchasing. If you are unsure, or if your vehicle has been modified, please reach out to a StreetFX agent.

Exhaust, Loud Mouth II, Cat-Back, Stainless Steel, Natural, Polished, Tips, 5.7L, 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.
