XForce 6”x10”x15” Varex Polished Stainless Steel Universal Oval Exhaust Muffler with a 3-1/2” Center Inlet and Tip.
If you can’t pick between an aggressively loud or mellow, street-friendly exhaust note, get them both with XForce’s 6”x10”x15” Varex Polished Stainless Steel Universal Oval Exhaust Muffler with a 3-1/2” Center Inlet and Tip (VMK11-350)! This muffler uses a complex internal butterfly valve controlled by remote key fobs to switch between a straight-through and chambered sound management system. In the open position, the valve lets the exhaust fumes flow unobstructed for a rich, throaty, race-inspired note. When the valve is closed, the exhaust flow is rerouted through chambered paths for a classic, pleasant sound.
Features and Benefits:
- Adjustable exhaust note
- Universal fitment
- 304 Stainless Steel Construction
- Polished to a sleek mirror-like finish
- Internal electronic butterfly valve
This flexibility is perfect for daily drivers that double as racecars, giving your neighbors some peace and quiet when you leave for work while letting the competition know you’re closing in on the strip. To top it all off, this muffler is constructed of durable 304 stainless steel and polished to a sleek mirror finish for excellent style.
Tech Tip: XForce recommends allowing 2” of clearance for the Varex Actuator.
Please Note: Professional installation is highly recommended.
