Iperformance Outperforms RK Sport Header!
Stan's Header Made 5.1 MORE HP AND 5.4 MORE FT-LBS OF TORQUE than RK Sport at 4,600 RPM!!!!!! Click the link to read about Mike Raque's dyno testing of this product. Constructed of heavy 14 gauge aluminized steel pipe, mandrel bent, with heavy flanges and quality welds for long life.

Tri-Y header design for these applications is exclusive to Stan's, ensuring the widest power band and more usable horsepower and torque for the best acceleration at the track or on the street.

1 1/2 inch primary pipes, 2 inch secondary pipes, and 2 1/2 inch collector, for 26% more flow than any other exhaust system for these cars on the market. Three piece construction for easiest installation.

Woven steel flexible joint ensures that the twisting of the engine will not loosen the bolts or crack the pipes, far superior to competitor's designs without this feature which are susceptible to these problems. Fitting for primary O2 sensor is fitted behind the final collector for most accurate reading from all cylinders offering smoother running and better fuel economy than competitor's designs. Secondary O2 sensor fitting after the catalytic converter as per GM design.

Large, high flow, 2 1/2 inch inside diameter Carsound (Magnaflow brand) catalytic converter included, making this the only complete header available for these cars which complies with emissions laws. Header not available without the catalytic converter.

We use only Carsound/Magnaflow brand catalytic converters with our headers because lesser quality catalytic converters are not compatible with the ODB II emissions systems of these vehicles and will trigger error codes that will flash the check engine light.

2 1/2 inch mandrel bent, aluminized exhaust pipe for 26% more flow than any other exhaust header for these cars and long service life. High exhaust flow capacity make this header ideal for supercharged and nitrous applications as well as all naturally aspirated engines from mild to wild.

Header offered only as complete unit, not available as individual parts. Offered only as complete unit, not available as individual parts. All hardware required for installation included: nuts, bolts, washers, lock washers, and clamp needed to assemble the three pieces of the header assembly.

Upper copper header gasket, and lower steel and fiber composite catalytic converter gasket also included. Available with optional ceramic coating.

Our ceramic coating is done by Reliable Metal Finishing using Tech Line brand ceramic coatings. Tech Line is the industry leader in ceramic coatings supplying materials to the majority of companies offering ceramic coating service for automotive applications. For headers, we use a Tri-Coat system consisting of MCS Insulating Coating inside the pipe and MCS Insulating Coating under MCX Cermakrome on the outside of the pipe. The MCS Insulating Coating withstands over 2,400 degrees and drastically reduces under hood temperatures. The MCX Cermakrome combines high heat tolerance and maximum heat insulation with the most durable finish available for superior weather and abrasion resistance. The multiple coatings combine for a finish unmatched by the offerings of any other header manufacturer anywhere.

Please note that the use of header wraps, on any header, accelerates the deterioration of the steel by causing heat fatigue, and will in all cases result in rapid, premature failure of a header.

Plain steel header shown, bluish discoloration of the steel is due to the heat of welding the header together.

An excellent upgrade replacement for owners headers by RK Sport, RSM Motorsports, Mantapart, or Pacesetter. Please be sure to specify year of car on order form.
