These titanium components are resistant to rust and corrosion, which can be a common issue with traditional steel studs and nuts. This corrosion resistance ensures that the studs and nuts maintain their integrity, allowing for easy removal and installation when necessary. They are the perfect upgrade for Porsche enthusiasts who demand the ease of access to vehicle's exhaust system.

Heat exchanger sets, Stainless Steel.

Improve exhaust gas flow using these "big bore" SSi heat exchangers.
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.

Price is for a SET OF 2

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.
