The X-Pipe section evens the exhaust pulses with a synchronized crossover in the center section resulting in a deeper, smoother tone. Hand-crafted from the finest T304 stainless steel materials and mandrel bent for a perfect fit. The Billy Boat Corvette X-Pipe provides a smoother transition for the exhaust pulses to blend together for better balancing and scavenging. No emission components are altered with this X pipe and it is emissions legal in all 50 states.
