About this product

Part #: 817550

Flowmaster's Force II Cat-Back system for the 05-13 Corvette (C6) is perfect for the person looking for mild to moderate sound levels with all of the performance benefits that you would expect from Flowmaster. The stainless steel system features a 2.50" Scavenger X-pipe assembly that bolts to the flanged connections behind the catalytic converters. The mufflers are the same 60 series units as used in our current Axle-back system, which provide a very pleasant tone inside the car that most Corvette owners will enjoy. The mufflers are painted black, and include polished, split 4.00" tips for a "Quad" exit style. The exhaust system is manufactured in the USA and is covered by Flowmaster's Lifetime Limited Warranty. Designed for an easy fit, this system includes all necessary parts and hardware for installation. The system is not intended or listed for Grand Sport models. It will fit and perform well, but the "Active Exhaust" function will be disabled.

What made you choose this particular product?
LIKE: Aggressive sound, Black muffler, qp Cold starts, Chrome tips DISLIKE: Not much to dislike LABOR: Did it myself INSTALLATION: Step by step instructions, NOTE: make sure you measure and mark before you cut off old exhaust, Took around 3 to 5 hours (took my time) PERFORMANCE: Deep aggressive sound, allows more air to flow. RECOMMEND: I would RECOMMEND for those who are comfortable cutting exhaust, but professional installation also encouraged if you arent up for the challenge.
