Product Details

The most sought-after heat exchangers on the market!  Made entirely of AISI 304/321 stainless steel, these heat exchangers feature high-flow equal-length mandrel-bent 304 stainless steel tubular headers encased in 0.75mm 304 stainless steel heater ducting.  Welding is done by argon shielded TIG, and high-energy spot welding.

Output is increased particularly in the low and middle RPM ranges. The design makes power by minimizing intake charge disturbances at valve overlap, and increasing the exhaust gas extraction effect. The volumetric efficiency, and thereby the power output is increased. The SSI headers are significantly improved versions of the basic header design used by Porsche® on all normally aspirated six cylinder competition engines.  Gas flow rates exceed O.E. by 9.8% and are balanced within 1.7%.

Radiated heat loss is reduced 46% due to the low thermal conductivity of the ducting. Operating temperature is reached 42% faster. Heat loss due to leakage is reduced to near zero. The passenger compartment will warm up faster, and to a higher temperature. The defroster will clear the windshield in slightly more than half the time previously required. Thermocycle will not loosen the ducting and create leakage and ducting rattles.

Normal torque improvement at 3000 RPM is +30 ft. lbs.
