The Racing Beat REV8 "Street Legal", Cat-Back RX-8 Exhaust System (Single Outlet Tips) for the 2009-11 RX-8 is the perfect replacement for your stock exhaust - a durable assembly offering a real horsepower gain over your stock unit. Our system consists of a 304 stainless steel Racing Beat connecting-pipe, muffler canisters, tubing, flanges, and outlet tips. The replacement connecting-pipe is manufactured using 3-inch (OD) tubing and features cast stainless steel flanges for positive exhaust gas sealing. The stainless steel muffler canisters are each finished with 4-inch, polished 304 stainless tips for an aggressive look. (2009+ RX-8 exhaust systems differ with regards to the positioning of the outlet tips and are NOT compatible with earlier RX-8 models.)

Power Output
Utilizing our in-house dyno test facilities, the Racing Beat engineering staff has undertaken exhaust system extensive testing with the RX-8 Renesis engine. Our research has found that simply adding a large-diameter, "straight-through" muffler is very loud, and power gains are only modest. We focused our 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.

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

Sound Quality
Takayuki Oku, Racing Beat's co-founder and chief exhaust designer, has spent considerable time and effort in an attempt to fine-tune the internal canister design of our muffler canister to provide what he believes is the ultimate rotary exhaust note!!! As he notes, "A little bit of my blood, sweat, and soul is in everyone of these RX-8 mufflers!" During development of the exhaust he worked extensively to find the optimum balance between power and sound level. Too much sound dampening would rob power; too little dampening would bring the exhaust note up to unacceptable levels.
