MUFFLER RX8 04-08, RACING BEAT
MUFFLER RX8 04-08, RACING BEAT
Power Output
Utilizing in-house dyno test facilities, the Racing Beat engineering staff has undertaken exhaust system extensive testing with the RX-8 Renesis engine. Their research has found that simply adding a large-diameter, “straight-through” muffler is very loud, and power gains are only modest. They focused their development efforts on optimizing the power output, while maintaining a moderate, but aggressive exhaust tone.
Based upon our initial test sessions, it appeared that the Mazda engineers did not leave much “untapped” horsepower behind in the stock exhaust system. Although it appears there might be modest power gains available from a “cat-back” exhaust system, be wary of big horsepower claims from any aftermarket exhaust system.
Racing Beat’s testing has provided the following results:
Stock production engine – with muffler removed +5 HP
Stock production engine – with RB muffler + 3.5 HP
Stock production engine – with aftermarket system “A” muffler + 3.5 HP
Stock production engine – with aftermarket system “B” muffler + -1.5 HPSKU: 16397 -

MUFFLER RX8, RACING BEAT “RACE”
Power Output
Performance gains are comparable with Racing Beat REV 8 Street Exhaust:Stock production engine – with muffler removed +5 HP
Stock production engine – with RB street or race exhaust + 3.5 HP approx.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, our independent test driver commented 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.

MUFFLER UNIVERSAL STAINLESS 3.5″ RACING BEAT
Racing Beat Universal Stainless 3.5″ Muffler
Power Pulse Race Muffler – 3.5″ ID – 304 Stainless Steel – This all new race muffler was developed in mind for the high horsepower engines requiring maximum flow with sound reducing performance. Constructed from 304 stainless and packed with stainless/ceramic wool, this muffler designed to hold up to the extreme temperatures of the rotary engine.
We strongly suggest incorporating the Power Pulse race presilencer unit in your custom exhaust system to further reduce the exhaust tone produced by the rotary engine.

RACE EXHAUST SYSTEM V2 EXTENDED TIP, 04-08 RX8 (RACING BEAT)
Racing Beat Race Exhaust Systim V2 Extended Tip, 04-08 RX8
The Racing Beat RX-8 Race Exhaust System V2 extended tip is a lightweight exhaust system that is intended for race applications. Originally designed to meet the demands of RX-8 autocross/circuit racers, this system is significantly lighter than the stock system and has been designed to meet a race track-imposed sound limit. As compared with the original RX-8 Race exhaust system, the V2 version features an extended tip section which extends rearward through a single bumper opening.
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 (21 lbs) + Connecting-pipe (8 lbs) = 29 lbs
This is a 25% 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, Racing Beat 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.
Power Output
Performance gains are comparable with Racing Beat’s REV 8 Street Exhaust:Stock production engine – with muffler removed +5 HP
Stock production engine – with RB street or race exhaust + 3.5 HP approx.Sound Quality
