FEATURES

CONSTRUCTION ENTIRELY OF AISI 321/EN4541 TITANIUM STABILISED 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 currently tested AISI 321/EN4531 titanium stabilised stainless steel. There are no internal weld joints made during fabrication.

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 metal is 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.

„doing it the right way“

Matthias has been building Porsche engines and servicing Porsche race- and sports cars for over 25 years. In the American Porsche scene, Matthias is a well-known name, ever since he has looked after the engines of the race cars for Porsche Motorsport North America in the 2000s and worked closely with well-known collectors, like Magnus Walker and others.

His experience includes building Porsche 993 GT2 race engines, manufacturing prototype components for the Bugatti Veyron, manufacturing engine parts for Arrows F1, and building and testing Porsche 996 and 997 RSR and Cup engines. Matthias is obsessed with the top-level motorsports ethos of „doing it the right way“, and he now focuses primarily on utilizing his expertise and worldwide network in order to find and market exceptional automobiles for his clients.

WHY SSI?

Porsche afficionados know SSI (stainless steel innovations) as one of the premium brands in the aftermarket. SSI, originally from California and its exhaust systems were one of the few American parts for Porsche that were – and still are! – coveted all over the world.
