SLP 05 GTO "Loud Mouth II" Exhaust w/PowerFlo-X Crossover Pipes

A Modular Exhaust System to Wake Up Your 2005 GTO!

Bolt on a Loud Mouth® II modular catalyst-back exhaust system from SLP on your new 2005 GTO for up to 5 extra horsepower and 5 foot-pounds of torque with the aggressive musclecar rumble your LS2 deserves. Not quite as loud as our original Loud Mouth, 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 valence. 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 valence. The modular design gives you flexibility to change to a louder system in minutes by purchasing a pair of bolt-in Loud Mouth resonators (#31062). The exhaust system is hand-crafted from 2.5” 304 stainless steel, and is covered with our Limited Lifetime Warranty.
