New from Summit Racing — the full-length Dynatech SuperMAXX headers for street-driven vehicles. These headers feature race car technology for big horsepower and torque gains. See more details below.
Dynatech put race car header technology into its line of SuperMAXX headers for street-driven vehicles. These are not shorty-style headers—SuperMAXX headers are full-length designs that build serious horsepower and torque. Dynatech put a pair of SuperMAXX’es on a C5 Corvette and gained 30 horsepower and 30 lbs.-ft. of torque. The company says adding a good tune will add another 20 to 25 horsepower.
SuperMAXX headers are made from T-304 stainless steel, and most headers feature large 1 3/4 or 1 7/8 inch mandrel bent primary tubes for maximum flow. Oxygen sensor extension cables, triple layer stainless steel gaskets, header bolts, and installation hardware are included. The pipes are available for many 1997-2017 GM, Ford, and Mopar V8 cars and trucks.
Summit Racing also offers these Dynatech SuperMAXX products:
Header Systems for C5 Corvette
These systems combine a pair of SuperMAXX headers with a high-flow, merge-style Y-pipe with a slip-fit union for easy installation without welding. They have provisions for O2 sensors and are fully OBD-II compatible. Summit Racing currently has SuperMAXX systems for 2001-03 C5 Corvette.
Y-Pipes and Intermediate Pipes
These high-flow pipes are designed to work with SuperMAXX headers to provide maximum exhaust flow. They feature a slip-fit union for easy installation without welding, plus a self-aligning, sintered-metal donut gasket for a leak-free connection. Some SuperMAXX Y- and intermediate pipes come with stainless steel, high-flow catalytic converters. The pipes are available for many 1997-2017 GM, Ford, and Mopar V8 cars and trucks.
