A Modular Exhaust System to Wake Up Your 2005-2006 GTO! Bolt on a LoudMouth II® Modular Cat-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. Not quite as loud as our original LoudMouth®, the system's great sound comes from a pair of stainless bullet mufflers complete with embossed SLP logo. Our engineers developed a great sound for the street without objectionable in-cabin resonance. The additional performance comes from the free-flow design and our built-in PowerFlo-X® Crossover system that borrows a power-building technique widely used in stock car racing. The system features a pair of distinctive 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 at a 90 degree angle so they match the curving shape of your rear valance. The modular design gives you flexibility to change to a louder system in minutes by purchasing a pair of bolt-in resonators (#31062). The exhaust system is hand-crafted from 2.5" stainless steel, and is covered with our Limited Lifetime Warranty.
