Unlock serious horsepower from your Mustang GT 5.0L Coyote V8. Ramjet’s equal-length, double-stepped long-tube headers and high-flow cats are engineered to perfectly time exhaust pulses — for a broader powerband, sharper throttle response and a crisp, exotic V8 note unequal headers simply can’t match. Manufactured from premium 304 stainless steel and built to bolt straight onto your factory cat-back.
