– 2 hole flanges inner diameter 47mm

 For cars without stub in exhaust port

Fits for:
– Porsche 911 G-model C1 3,2l Carrera – engine conversion to 3,6l

Features:
– Constructed entirely of AISI 304/321 stainless steel
– State of the art header design: All six primary tubes are equal in centerline lenght to 7.9 mm absolute, vs original equipment variances of 95.3 mm. All tubing is three ball mandrel bent to aircraft tolerences on computer controlled tube benders to assure consistent tube inside diameters. Gas flow rates exceed O.E. by 9.8% and are balanced within 1.7%. All turbulence inducing compound bends have been eliminated from the design.
– One piece header primary tubes: Primary header tubes contained in the heat exchanger ducting are made of one piece Eddy current tested AISI 304 stainless steel tubing. There are no internal weld joints made during fabrication.
– Long life: Expected life in the severest conditions (road salt) is 20-30 years
– Higher power output: 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.
– Carbon Monoxid Safe: Unlike all other aftermarket heat exchangers, the SSI heat exchanger headers are made to minimize the possibility that engine produced acids will internally corrode the enclosed primary tubes, thereby allowing carbon monoxide to enter the passenger compartment. The AISI 304 stainless steel tubing is highly resistant to the byproducts of combustion. We use only one piece primary tubes, eliminating the possibility of hand-made welds cracking, and the resulting carbon monoxide leaks.
– Highly functional ducting: Heater ducting is precisely formed of low thermally conductive 0.75 mm AISI 304 stainless steel. It is carefully fitted to the header heat source to minimize leakage. The identical alloy ducting and header materials have like thermal expansion rates which prevent stretching and loosening of the ducting on the headers.
– Absolutely the highest quality heat exchangers made anywhere, by anyone at any price: These parts are beautiful to look at, and a joy to install. Every detail has been attended to. The sheet metalis formed and trimmed on Class A perminate tooling. Welding is argon shielded Tungsten Inert Gas (TIG), and high energy spot welding. Precise fixturing is used in all assembly processes. Materials are only prime quality. SSI has manufactured and sold far more heat exchangers for Porsche® cars than any other after-market manufacturer in the world. Production began in 1976, and our last known defect was in February, 1978.
– More heat, faster and no rattles: 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.

– Reduced installation time, enhanced vehicle value: SSI heat exchangers fit perfectly. Installation time and costs are reduced. They will NEVER need to be replaced, as they will outlive the vehicle on which they are installed. Their unequalled quality, performance, and longevity will enhance the value of a Porsche® throughout its life.
