Heat exchanger sets, Stainless Steel. Porsche 911 3.2L Conversion SSI ❭ 91133091917SSI
- Porsche 911 1984-1986 3.2L
- Porsche 911 1987-1989 3.2L G50
Are you backdating a 3.2 Carrera or 3.2ltr engine?
Use these SSi heat exchangers to solve the exhaust requirements by deleting the pre-silencer and turning the rear silencer into a "two in, one out" system seen on the early, pre impact bumper cars.
Fits:
Porsche 911 3.2L Conversion SSI
*Oil pipes 91110772910 and 91110773910 are also required also see our exhaust packages
Modification is needed on the engine tinware when installing on 3.2ltr engines.
LONG LIFE
Made using AISI 321/EN4531 titanium stabilized stainless steel the expected life in the severest road conditions (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 MONOXIDE 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. SSI use only one piece primary tubes, eliminating the possibility of hand-made welds cracking, and the resulting carbon monoxide leaks.
