SLP Performance 31561 LoudMouth II Stainless 2.5" Cat-Back Exhaust System

BKSC31561
SLP's Loud Mouth II Cat-Back Exhaust System for the 05-06 GTO adds 5 extra horsepower and 5 foot-pounds of torque with the aggressive muscle-car rumble. Not quite as loud as our original Loud Mouth, the system's great sound comes from a pair of stainless bullet mufflers. 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 Loud Mouth resonators (# 31062). The exhaust system is hand-crafted from 2.5" stainless steel, and has a Limited Lifetime Warranty.
