New at Summit Racing: XForce Mufflers

Some new musclecars—Camaros and Hellcat Challengers come to mind—have adjustable mufflers or exhaust systems so you can alter the sound level to suit driving parameters. For example, the sound can be toned down for in-town driving, have a little more bark on the highway, or turned up past 11 when you’re feeling your oats on the track.

Now you can have that kind of sound control for your own car with XForce Varex Mufflers.  The mufflers feature a butterfly valve mechanism driven by an electric motor. The valve redirects the exhaust gas flow based on the driver-selected sound level. For a mellow sound, exhaust gas goes through the muffler’s chambered system (similar to a factory high performance muffler). When you want to go nuclear, the exhaust gas goes through the center tube, much like a straight-through muffler. Since the angle of the butterfly valve is infinitely adjustable, you can set the sound at any level between the two points.

XForce Varex Mufflers are universal-fit and made from polished 304 stainless steel. They require no hard wiring to the vehicle—the control module plugs into a 12V power socket inside the car. The mufflers come with the control module, wiring harness, and a remote to adjust the sound level. A dual-plug wiring kit is available for cars with a dual exhaust system.

Summit Racing also offers XForce Varex Cat-Back Exhaust Systems. The fully stainless steel systems feature a pair of Varex mufflers, tubing, exhaust tips, and muffler control module and remote. Current applications include 2010-15 Camaro, 2016 Camaro SS, 2015-16 Mustang 2.3L Ecoboost, and 2008-09 Pontiac G8.
