Upgrading the exhaust system on a rotary engine car has always proven to be the easiest way to increase performance in the past and the same holds true for the 3rd generation RX-7. When upgrading the system, you want to improve flow as much as possible for maximum power. If you drive the car on the street, then you must have a catalytic convertor to remain emissions legal. Otherwise, off-road cars used exclusively on the race track will get the biggest power gains from a racing system. Our Bönez exhaust lineup features mandrel-bent, thick-walled 304 Stainless Steel with 1/2" flanges for maximum durability and longevity. Additionally, each and every exhaust component is test fitted on our jig to ensure perfect fitment.

Bönez 3" DownpipeDownpipes are one of the most popular and important changes you can make for your FD. Everyone knows how hot our cars can get under the hood. A large part of this is from the radiating heat of the factory pre-catalytic converter. This heat rapidly damages underhood parts, lowers performance and shortens engine life. Removing this and installing a downpipe will improve turbo spool, lower heat, increase performance and help mileage. The Bonez downpipe utilizes a 3" mandrel bent design and is fully Stainless Steel. The pipe is a completely bolt up design and connects from the stock turbos back to the stock or a performance main cat. Note: Since this eliminates the pre-converter, it is sold for racing use ONLY!

Bönez 3" Main Converter The exhaust heat produced by a rotary engine is much higher than that of a conventional piston engine. This created quite a problem for us in our quest for an aftermarket catalytic converter that could perform up to our demanding expectations. After trying nearly every aftermarket cat available, we found that they all use a standard type suspension material around the ceramic converter brick. This material is not designed to endure the tremendous heat of the rotary exhaust which causes it to fail prematurely. Once the suspension material has overheated and broken down, the ceramic converter brick is left loose to rattle inside the case. The loose ceramic brick eventually causes its own self destruction, increased backpressure, and excessive noise.

After extensive research and development, we are proud to present the Bönez catalytic converter. Unlike other aftermarket catalytic converters, the Bönez unit uses a stainless steel mesh suspension element that surrounds the large, high flowing converter brick. This suspension element is built to withstand extreme termperature demands, and provide many miles of dependable performance. The case is also constructed of stainless steel for better durability, and incorporates a unique design which causes the inlet exhaust gases to spread evenly over the brick for better flow, improved efficiency, longer life, and reduced noise. This item fits between your stock precat or performance downpipe and will bolt directly to the stock catback system or any other aftermarket catback system. The Bönez kit also is much lighter than the stock unit it replaces and noise levels are only slightly increased. Please also note that the oxygen supply tube from the air pump is still retained, making this system 100% bolt on.

Bönez 3" Performance Converter SystemThe Bönez Performance Converter System is an excellent option for those seeking a street legal system that provides improved performance, better gas mileage, and less stress on the engine and turbos. Our kit replaces both of the stock catalytic converters with a smooth, mandrel bent racing downpipe and a center section which utilizes one of our unique, 3" high flow converters. This combination gives you the most power possible while still remaining emissions legal, as well as lasting much longer than any other converter available on the market. This kit is completely bolt up and replaces everything from the turbos back to the stock or aftermarket cat-back exhaust. The oxygen supply tube is also retained.
