Adjustable Sound. By installing a XForce Varex Turbo-Back System, you can dramatically change the sound of your WRX STi ‘s exhaust from the quiet factory sound to the deep boxer rumble we’ve come to love anywhere between with just a push of a button. This XForce Varex system features a pair of electronically adjustable Varex performance mufflers. Close them when driving through a residential area to stay low key. Then open them up to unleash the deep boxer rumble while speeding down the highway.
How It Works. XForce Varex performance mufflers utilize a sophisticated internal electronic butterfly valve mechanism to direct the exhaust flow within the muffler. In the open position, the valve “uncorks” the exhaust flow allowing it to take the path of least resistance. The muffler now acts more like a straight-through muffler for a rich throaty race style exhaust note. In the closed position, the valve blocks the exhaust flow, forcing it through the chambered paths to produce a classic, mellow street friendly sound. This unique design is perfect for personalizing the power and sound levels of your WRX to suit your own specific needs.
Full Exhaust Kit. The XForce Varex Turbo-Back System Kit is a complete 3″ system from a 3 inch dump pipe, a 3 inch high flow cat, a 3 inch centre section with a resonator, and a 3 inch twin rear section with oval Varex mufflers and quad tips.
Stainless Steel Construction. This XForce Varex Exhaust System is manufactured from high quality stainless steel tubing for superior durability and corrosion resistance.
Direct Bolt-On Installation. Engineered to be a direct upgrade replacement, this XForce Varex Exhaust System will easily bolt on without any modifications required for a straight forward installation. The control module that powers the muffler butterfly valves can be plugged into your Subaru’s 12v accessory outlet for easy plug and play operation or permanently hard-wired to a 12v source – the choice is yours.
Application. This XForce Varex 3″ Turbo-Back System is designed as a direct fit bolt-on upgrade for all SUBARU WRX/STi SEDAN 2011-
