The BBK high-flow after-cat X-pipe for 2010–2015 Camaro SS LS3/L99 uses 2.75" CNC mandrel-bent stainless tubing and a merged crossover to reduce backpressure and improve exhaust flow. Positioned after the catalytic converters, it replaces restrictive resonators to increase horsepower and torque while maintaining emissions control. It’s a direct-fit upgrade created for Gen 5 Camaro applications seeking freer flow and a fuller exhaust tone.
