RX-8 Race Exhaust System The Racing Beat RX-8 Race Exhaust System is a lightweight exhaust system that is intended for street or race applications. Originally designed to meet the demands of RX-8 autocross racers, this system is significantly lighter than the stock system and has been designed to meet a race track imposed 92db sound limit*. System Weight The Racing Beat Race Exhaust System has been designed to offer a significant weight reduction over the stock RX-8 system, compare the following: Stock system + connecting-pipe = 39 lbs Racing Beat Race Muffler (17.5 lbs) + Connecting-pipe (8 lbs) = 25.5 lbs This is a 34% reduction in weight over the stock system! All components are handcrafted using 304-stainless steel materials for excellent durability and strength. As a weight saving measure, we decided to eliminate the decorative tip outlet, and instead provided a downward-angled outlet pipe. This pipe reflects exhaust noise downward in an attempt to further dissipate the sound. To view a larger photo of the complete exhaust system, click here. Power Output Performance gains are comparable with our REV 8 Street Exhaust: Stock production engine - with muffler removed +5 HP Stock production engine - with RB street or race exhaust + 3.5 HP Sound Quality While louder than the stock system, particularly under full throttle, this exhaust system can be used for those looking for a very aggressive exhaust tone for their daily-driven RX-8. A modest driving technique will produce a moderate and tolerable exhaust tone, but jump on the throttle and this exhaust really comes to life. Full throttle does not produce a buzzy or harsh, but a more exotic sound like that of a tuned V-6 engine. During a long-distance trip to the race track during prototype testing for this system, Racing Beat's independent test driver (that's us here at Good-Win Racing) found that highway cruising was very tolerable, without any droning sounds or harmonics. This exhaust system is equipped with a stainless steel connecting pipe and all required mounting hardware. *Measured approximately 50 away from the side of an otherwise stock 2004 RX-8 MT under full throttle. Your actual decibel reading may vary. Other factors, including atmospheric conditions, additional performance accessories, tires, etc.. may cause variations in your actual sound measurement.
