xForce's Revolutionary Varex Muffler

What is the VAREX muffler you say? Well, let us shed some light on the situation. xForce has invented and patented their own exhaust system technology which combines both a stock muffler and a performance muffler into the one compact unit. Using a butterfly valve mechanism, an xForce exhaust can redirect the flow of exhaust gasses between the two mufflers.

Why is this a benefit for customers? Because it means YOU get to control how your exhaust sounds in different situations and locations. If your parents or neighbours frequently complain about how loud your car is, with the press of a button, you can transform your exhaust back to its stock sound level. When the butterfly valve is closed, exhaust flow is redirected through the chambered path of the muffler (similar to a “stock muffler”), enabling lower sound levels and maximum discretion.

Similarly when you want greater power output and sound level, you can open up the butterfly valve completely, allowing exhaust gasses to flow straight through the muffler system.

But what if you want something in between? xForce have got you covered here as well. You see, the angle of the valve is completely controllable and can be adjusted at any angle between fully open and closed to achieve the perfect sound level.
