Description
Can an exhaust system deliver enough power to literally knock your socks off? Let's just put it this way: when you equip your mean machine with Dynatech's SuperMAXX Exhaust System, you'd better lace up your driving shoes tight. Each system is custom engineered and dyno proven to unleash massive wallops of real, usable, seat-of-the-pants horsepower and torque across the power band.

Your SuperMAXX Exhaust System doesn't just push the envelope of street performance-it air mails it to Timbuktu. The potent combination of the SuperMAXX's long-tube headers and the high-flow catalytic converters boosts exhaust flow by up to 106%! Select systems even come with a NASCAR style X-pipe. Plus, the whole system is built to last from T-304 stainless steel.

No chop jobs required-just unbolt your old exhaust manifolds and cats, then pop your shiny new SuperMAXX in its place. Your stock mufflers stay put, and you get triple-layer steel gaskets, clamps and mounting hardware.
