Heat exchanger set, stainless steel, Ø41 mm outer tubes, left / right.

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.
Made using Ø41 mm outside tubing for a better flow and performance these AISI 321/EN4531 titanium stabilized stainless steel heat exchangers offer long life, increased power output and a quality fit.

IMPORTANT: Major modification needed on engine tin ware when installing on 3.2ltr engines.

Price is for a SET OF 2

Fits:
Porsche 911 (Conversion) 3.2ltr 08/1983 - 07/1989

Core Length: 470 mm
Core Width: 760 mm
Core Depth: 380 mm
Outer diameter: 41 mm

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 by products of combustion. SSI use only one piece primary tubes, eliminating the possibility of hand-made welds cracking, and the resulting carbon monoxide leaks.
