3" Cat-Back Exhaust w/SS Tips 2010-2015 Camaro SS Connects to OEM

Kooks 3-Inch Stainless Steel Cat-Back Exhaust with Polished Tips for 2010 and 2015 Chevrolet Camaro SS 6.2L LS3/L99

The Kooks 3-inch cat-back exhaust system delivers the ultimate bolt-on performance upgrade for 2010 and 2015 Camaro SS models with the 6.2L LS3 (manual) or L99 (automatic) V8, replacing the factory system from the catalytic converters back with mandrel-bent T304 stainless steel tubing and high-flow straight-through mufflers for dyno-proven gains of 20 and 30 rear-wheel horsepower and 25 and 35 lb-ft of torque while producing an aggressive V8 roar without interior drone.

Featuring polished 4-inch double-wall slash-cut tips and full TIG-welded construction, this system maintains factory ground clearance and uses OEM hangers for direct bolt-on installation with no cutting or welding required. The 3-inch diameter flows significantly better than stock 2.5-inch piping, supporting over 600 HP modifications while retaining factory Active Exhaust valve function (where equipped) for seamless Quiet, Normal, Sport, and Track modes.

For 5th-gen Camaro SS owners demanding deeper tone and real power gains with daily-driver refinement, the Kooks 22504200 cat-back is the complete solution for street, track, or show.

Frequently Asked Questions

• Q: Does it keep Active Exhaust valves?
  A: Yes, full compatibility with factory valves
• Q: How loud in Track mode?
  A: Deep aggressive roar louder than factory Track
• Q: Drone at cruise?
  A: Zero drone in Normal/Touring modes
• Do Kooks headers require a tune after installation?
  Yes. A professional tune is strongly recommended after installing long tube headers. The significant improvement in exhaust flow changes air fuel ratios and requires ECM recalibration to achieve optimal power output and safe operation.
• Will these headers void my factory powertrain warranty?
  Under the Magnuson-Moss Warranty Act, a manufacturer cannot void your vehicle warranty simply because you installed an aftermarket part unless they prove the component directly caused the failure. Consult your dealer for specifics on your situation.
