The Cornerstone Double Helix 3 inch stainless steel X-Pipe for the C7 is just the part you were looking for. This X pipe help make that exhaust sound like you always wanted it to. By moving it in the "X" pipe shape we were able to eliminate most of the exhaust drone and that resonating sound you get with these loud cars. All of this is combined with additional power and stainless steel construction to keep it on the road as long as you could ever want! 
Overall if you own a 2014-2019 Chevrolet Corvette also known as a C7 and are looking to make some exhaust changes this is something you don't want to miss out on, this is the exhaust part you have been looking for!
  • Bolts on to the factory exhaust with zero modifications
  • Eliminates resonance and exhaust drones
  • Mandrel bend design
  • Easy bolt-on installation

    This a great X pipe. Fit my needs as far as sound. I wanted something a bit louder without having to remove cats. Material was good.
