xForce Product Reviews
Sounds absolutely fantastic. With open valves it’s the perfect match between good sound and not annoying. Gargle's at lower revs, quiets down between 2-3k and opens right up after that. Also gives it the best cold starts ever. Nice and subtle when closed valves.
Better than I thought it would be. The X-Force with Varex Smartbox is brilliant. The sound is fantastic and the total control means I don't piss my neighbors off. Easy to install. Keep an eye out, you'll hear me coming!!
Great simple mod to enhance the exhaust. Changes the exhaust note of the i30N hatch to a much deeper pitch and tone which I prefer to the high pitched, tinny sound of the stock exhaust. Also gets more low rev burbles and crackles with only a slight increase in volume with pops and bangs in N Mode. Much prefer this to a res delete which just makes the stock exhaust note louder.

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.
