Expected life in the severest conditions (road salt) is 20-30 years. Price is for a SET OF 2
HIGHER POWER OUTPUT
Output is increased particularly in the low and middle RPM ranges. The design makes power by minimising 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 minimise 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.
