SLP Performance 31560 LoudMouth Stainless 2.5" Cat-Back Exhaust System

Bolt on a Loud Mouth Cat-Back Exhaust System from SLP on your 05-06 GTO for up to 5 extra horsepower and 5 foot-pounds of torque with the aggressive muscle-car rumble. The secret to the system's distinctive sound is a pair of stainless Loud Mouth resonators. 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 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.
