A Modular Exhaust System to Wake Up Your 2005 GTO!
Bolt on a Loud Mouth 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. The secret to the systems distinctive sound is a pair of stainless Loud Mouth 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 GTOs rear valence. 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 valence. The modular design gives you flexibility to change to a quieter Loud Mouth II system in minutes by purchasing a pair of bolt-in Loud Mouth II bullet-style mufflers (#31063). The exhaust system is hand-crafted from 2.5 stainless steel, and is covered with our Limited Lifetime Warranty.
