Porsche 911 (1974-1989) – exhaust – performance exhaust upgrades – cat bypass pipes, scart exhaust systems, ssi stainless steel heat exchangers e85 gas stations in iowa


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 m gasol 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 gas bloating back pain 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 electricity 101 pdf 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 n gas price 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 electricity lessons ks1 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.

Why are SSIs so legendary in the Porsche marketplace? Let’s talk gas 1940 hopper first about technical details. The most important decision a manufacturer of heat exchangers can make is what materials to use in the tube work and the ducting. The ducting must fail first, otherwise carbon monoxide has the potential to leak from the tubes inside the ductwork resulting in a dangerous situation. To this end, SSI uses only time-tested stainless steel #304 (18% Cr, 8%+ NI) for both tubes and ducting. Why? The 304 steel tubing is highly resistant to the H2SO4 (sulfuric gas emoji acid) that is present in exhaust gas condensate. It has a corrosion rate of approximately 1mil/year in 5% H2SO4 at 190F. Road salts eat away at 304 stainless steel about twice as fast as exhaust condensate. Lower-quality 400-series stainless steel (chrome only and magnetic) is eaten away by sulfuric condensate about 5 or 6 times faster than the rate of 304 stainless steel. SSI only uses .065 304 electricity deregulation in california stainless steel for tubes and electricity history timeline .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. On the flow side of equation, the primary and secondary tubes on Porsche normally aspirated race exhaust systems are 62-69% of the primaries (which are sized first to determine at what RPM the engineer wants the peak torque to occur within realm of practicality). SSI heat exchangers incorporate these ratios into their 1.5 pipe diameter heat exchangers, echoing the electricity sound effect experience that the factory learned from racing.

So, which set do you need for your car? SSI has many electricity word search pdf different styles, with each one designed specifically to suit your application. The 1976 cars had a mid-year switch in configuration to the later-style gasket with the ring inside. If you use these gaskets on your 1976 car (check first), order the later style heat exchangers. All USA, Canada, and Japanese 911SCs from 1980-83 have 21mm flanges with appropriately sized exhaust studs. They require SSI models 91-915SSI. SSI heat exchangers are also available for 3.6 engine conversions! Be sure to order the style of heat exchanger that matches your engine, not your electricity and circuits test chassis, if you happen to have upgraded your engine in your car.

SCART Exhaust, with corporate headquarters and manufacturing located in Paris France electricity experiments elementary school, have been making superbly engineered and constructed Porsche exhausts since 2003. SCART offers the most extensive range of any Porsche exhaust company in the world, with over 200 part numbers available. Utilizing the latest in tooling technology, SCART’s highly skilled technicians bend, press, and weld by-hand the exhausts in their own French factory – this provides full oversight of the manufacturing process, RD, and the highest levels of quality control. By controlling k electric bill statement the entire process, SCART can ensure proper fit right out of the box. SCART sport exhausts are manufactured with 304L stainless steel (with a heat resistance double that of the standard 304 steel you’ll find in competitors’ systems).

How do they sound? Fantastic! The sound c gastronomie vitam under acceleration truly releases the full potential of the flat six – a glorious soundtrack! But just as important, while cruising, the sound is subdued. SCART guarantees that all of their exhausts have no droning. You will find sound clips associated with many of the SCART exhausts on these pages. We invite you to have a listen.
