THE HIGHEST QUALITY AND BEST PERFORMING EXHAUST SYSTEMS ON THE MARKET!
Competition Sidewinder mufflers use A-1's exclusive 'Magna Flo' muffler design built to A-1's specifications, incorporating a full 2 1/2" Hi-Flo straight through core design and constructed in 409 stainless steel with the inlet and outlet on the same end cap for fitment versatility. This design and construction will allow the muffler to flow equally to that of an open stinger upwards of 220hp, yet allows a clean even exhaust note and achieving a noise level under 90 decibels (sound levels may vary due to engine horsepower). Numerous 11 and 12 second quarter mile street/drag cars have achieved excellent performance results with these mufflers.
