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 HP

    Racing Beat REN.V2 RX-8 Race Pipe
    Resonated Catalytic Converter Replacement Race Pipe – RX-8 owners have discovered that a installing a non-resonated catalytic converter race pipe on a RX-8 can produce a surprising loud exhaust tone. If your racing application or local track requires a modest, quieter exhaust tone, then the Racing Beat REN.V2 resonated race pipe is the perfect solution.

    Racing Beat offers a 3″ OD fully stainless steel catalytic converter replacement pipe with dual resonators for RX-8 racing applications. Fitted with two (2) rotary-designed resonator units selected specifically for the RX-8 chassis. Each resonator is tightly packed with stainless steel wool for optimum sound supression and tone quality.

    Both our resonated and non-resonated pipe versions are direct bolt-on replacements for the stock catalytic converter section. Racing Beat replacement pipes utilize a genuine Mazda OEM rear mounting flange to ensure a secure fitment to the stock (or an aftermarket) exhaust system. Each replacement pipe is equipped with a sensor fitting for the oxygen sensor. (Note: Placement of the sensor in the pipe will cause the “check engine” light to be illuminated, but performance and engine systems for racing applications will not be affected.)

    Each race pipe comes complete with all required mounting hardware, gaskets, and installation instructions.
