# MagnaFlow 10805 Stainless Steel Valve Kit for 2018-2022 Ford Mustang

### Performance Overview

Get the Magnaflow Exhaust Cut-outs for that added edge on the racetrack! These Cut-outs will provide you with a solution for that slight edge over the competition by letting you "uncork" your motor! The Magnaflow Exhaust Cut-outs will let you release your motor's power instead of removing your existing exhaust system and replacing it with your racing exhaust system. The power is released by letting the exhaust gasses avoid the remainder of the exhaust system which is after the point where the cut-out is installed. By opening the cut-outs the backpressure will be released and you will get optimum gains in horsepower and torque. Magna Flow Exhaust Cut-outs are crafted from 100 % stainless steel. They are clamp-on and are perfect for customized applications. They let your engine breathe freely, giving you more power and better engine performance. The Exhaust Cut-out is so easy to install with no welding required with its slip-fit design. Control your exhaust flow with exhaust cut-outs from Magna Flow.
