SLP Loudmouth I Catback Exhaust - 2005-2006 Pontiac GTO (6.0L V8) - 31560

A Modular Exhaust System to Wake Up Your 2005-2006 GTO! Bolt on a LoudMouth® Modular Catalyst-Back Exhaust System on your new 2005-2006 GTO for up to 5 extra horsepower and 5 foot-pounds of torque with the aggressive muscle-car rumble your LS2 deserves. The secret to the system's distinctive sound is a pair of stainless SLP resonators, stamped with our SLP logo. The additional performance comes from the free-flow design and our built-in PowerFlo-X® Crossover system that borrows a power-building method used in stock car racing. The system features a pair of attractive 3.5" dual-wall stainless steel tips that look great peeking out of the GTO's rear valance. The tips have an angle cut and can angle downward in a traditional style, or rotated 90 degrees so they match the curving shape of your rear valance. The modular design gives you flexibility to change to a quieter LoudMouth II® system in minutes by purchasing a pair of bolt-in SLP bullet-style mufflers (#31063). The exhaust system is hand-crafted from 2.5" stainless steel, and is covered with our Limited Lifetime Warranty.
