Enjoy your Hellcat sound with the factory tip finish

Give your supported 2015-2020 Challenger Hellcat a Kooks rear exhaust upgrade while keeping its OEM tips. The system combines a 3" stainless X-pipe arrangement with 14" and 10" round race mufflers, joining the 2-3/4" factory-style front interface.

Keep the look, change the rear system

The OEM tips and their OEM clamps are reused. Underneath, 16-gauge mandrel-bent 304 stainless tubing joins the X-pipe and Kooks race mufflers. You get a changed rear exhaust specification while retaining the factory tip appearance.

Works with the factory-style front connection

The 2-3/4" inlet joins the OEM front system, or Kooks headers with matching OEM-outlet connection pipes. Clamps and installation hardware are supplied, with the original tip clamps retained for the reused tips.
