SSI Stainless Steel Heat Exchangers

For years, SSI has set the standard for Porsche stainless exhaust heat exchangers. Each unit is a literal work of art, with craftsmanship that rivals the finest German artisans. It’s a shame these beauties are hidden underneath the car when it’s on the road. Rust-proof and durable, they will last the life of your car and are basically indestructible! They are manufactured out of 100% stainless steel so they won’t rust. On older systems, rust can eat through the metal pipes, and leak carbon monoxide into the heater system – something that you want to avoid. Rust also eats away at the thin metal that surrounds the exhaust pipes. This results in lost heat that would normally be funneled to the cockpit. In addition, replacing your 1975 and later exhaust system with these stainless steel beauties is often good for about 15 more horsepower. Why is this? The SSI heat exchangers are based on the 1974 and earlier 911 exhaust design that was highly optimized for the Porsche 911 engine. 1975 brought about changes in the exhaust that severely limited the flow capacities of the engine, in order to make the engines pass stricter smog standards. The SSI 1974-style heat exchangers are a bolt-on replacement for all thermal reactor cars (1975-77). Using the SSI heat exchangers will make these engines run cooler, make 16 more horsepower (10%), and 28 ft-lb more torque at 3,000 RPM (26% improvement). In addition, the reduced heat from the SSIs will help the engines last much longer. 911SC engines can expect to see an addition of 30 ft-lb of additional torque at 3,000 RPM (increase of 24%). Before replacing your 1975 and later exhaust, check with local authorities to make sure that the swap is permitted under local smog laws. SSI only uses .065″” 304 stainless steel for tubes and .028″” for ducting. Other competitors use inferior quality 409 for tubes and 304 for the ducting only, as only the 304 has the elastic properties necessary for forming the ductwork.
