SLP Exhaust System, 1997-07 Grand Prix PowerFlo w/Dual/Dual Tips.
Bolt on a new Power-Flo™ catalyst-back exhaust system from SLP on your Grand Prix for up to 10 extra horsepower with a low, musclecar rumble. Our engineers specifically developed this system to sound great and build power for the V6 3800 standard or supercharged engine platform. It sounds more aggressive than stock on the street, but with minimized interior cabin resonance. This system features a pair of big 3.5-inch slash-cut stainless polished tips for a muscle car style that will look great on your car. The exhaust system is hand-crafted from stainless steel. The tubing is bent on state-of-the-art CNC bending equipment using mandrel-bend tooling to minimize exhaust gas restrictions that come with factory systems, and is covered with our Limited Lifetime Warranty.
