In 1984 Porsche increased the heat exchanger manifold down pipe diameter from 39mm to 41mm to increase exhaust gas flow.
Here that pipe diameter increase has been incorporated into the earlier type heat exchanger for that added benefit to all 3.0Ltr and 3.3Ltr cars from 01/1975-07/1983

LONG LIFE
Made from AISI 321/EN4531 titanium-stabilised stainless steel, these heat exchangers are built for durability, with an expected lifespan of 20-30 years in high-salt environments and even longer in milder conditions.
HIGHER POWER OUTPUTDesigned to optimise exhaust flow, these headers improve power output, particularly in low and mid-RPM ranges, by reducing intake charge disturbances at valve overlap and enhancing exhaust gas extraction. SSI headers are a refined version of Porsche’s competition-proven six-cylinder header design.
CARBON MONOXIDE SAFE
Unlike other aftermarket options, SSI heat exchangers are engineered to prevent internal corrosion from engine acids, reducing the risk of carbon monoxide leaks. Constructed from high-quality AISI 304 stainless steel with seamless primary tubes, they eliminate weak weld points that could lead to cracks and leaks.
