XForce 7-1/2” x 16” Polished Round Universal Varex Muffler with a 3-1/2” Center Inlet and Tip.
If you can’t choose between an aggressive race-style exhaust note and a smooth stock sound, get them both with an XForce 7-1/2” x 16” Polished Round Universal Varex Muffler with a 3-1/2” Center Inlet and Tip (VMK17-350)!
Features and Benefits:
- Remotely-adjustable exhaust path
- Switches from mellow stock sound to aggressive exhaust note
- Durable, corrosion-resistant 304 steel construction
- Polished, mirror-like finish
- Perfect for restomods and custom applications
This aftermarket muffler uses a complex, remote-controlled butterfly valve to switch the fume path between a straight-through design (open) and a classic chambered setup (closed). The 304 stainless steel construction is extremely durable and can easily withstand the abuse and corrosion common to the strip and street. This muffler is complete with a polished, mirror-like finish and 3-1/2” exhaust tip for a touch of custom style!
Tech Tip: XForce recommends allowing 2” of clearance for the Varex Actuator.
Please Note: Professional installation is highly recommended.
