Product Information
DesignTek Porsche 911 header is made of stainless steel. These are a direct replacement for the heat exchangers on 1965-74, but it will also work on 1975-1989 911 by replacing the necessary hardware (e.g. muffler, oil lines). Our header is designed to increase the efficiency of the gas flow and thus to raise the horsepower of the engine. It is also made of stainless steel to improve durability, and the flanges are CNC machined to enhance stability. Our header is designed to be direct bolt-on for easy installation. This header set includes 1 pair of headers, gaskets, and bolts/nuts for installation. **

Product Information
Fits:
Porsche 911 Chassis 1965-89 Fitted With M64 964/993 3.6L Engine
LONG LIFE
Designed 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.

Product Information
Set of 2 stainless steel heat exchangers for Porsche 911 (1965-1989) chassis fitted with the M64 3.6L engine from Porsche 964 and 993 models. This setup eliminates the side and center silencers, converting the rear silencer into a "two in, one out" system, reminiscent of early pre-impact bumper cars.Fits:

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.
