STYLE SLP Performance Parts, the aftermarket’s premier manufacturer of performance exhaust components, is pleased to offer the all-new C5 Power-Flo™ cat-back system for 1997-2004 Corvettes. The centerpiece of the C5 Power-Flo is its industry-exclusive cast aluminum tip, which was styled by a member of GM’s C5 design team and features a unique shape that conforms to the vehicle’s rear-fascia opening.
PERFORMANCE AND SOUND The C5 Power-Flo is equipped with a pair of application-specific mufflers that were specially designed to provide a rich, muscular exhaust tone while minimizing interior resonance. Improvements of up to 10 horsepower are possible, thanks to a drastic reduction in backpressure over the restrictive factory system.
Applications:
1997 - 2004 Chevrolet Corvette
