We can now offer this sought after single exit catback system for your Series 1 RX-8 from HKS.
Inspired and designed from endurance and GT racing in Japan, HKS developed its Hi-Power Exhaust system for turbocharged applications. HKS has incorporated this new race inspired offset muffler and piping design into many street applications, which offers a greater flow and higher-PRM power gains due to the less restrictive design. This is achieved by eliminating unnecessary bends for the straightest exhaust path.

• HKS Hi Power Catback Exhaust
• Piping Diameter – 75 mm
• Tip Diameter – 97 mm
•  Single Sided Exhaust for N/A and  Turbo Applications with Adjustable Length Ti Tip
• Lighter then full twin tip backboxes.

The Racing Beat RX-8 Race Exhaust System V2 with 3″ bore and 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 our 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, 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.

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 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.

Nur Touring systems are generally quieter than other systems, please check individual product info for the decibel rating.

This is a genuine Mazda rear O2 sensor (found installed in your catalytic converter) for your RX-8 in many cases installing a pattern sensor will mean that cat monitoring (whitch is primarily what your rear O2 sensor is for) will not work correctly, we have found in the past that customer who have ionstalled a cheaper pattern or universal rear O2 sensor have had a failed cat however the ECU has failed to detect this.
This is the sensor that is installed in the catalytic converter.
Please note that there are 3 different sensors depending on your vehicle. Please select your correct part from the drop down menu.

Exclusive to Essex Rotary in the UK

Essex Rotary are very excited to bring to the UK the most anticipated exhaust header of all time for the RX-8, The Black Halo Racing Long-Tube Manifold.

This header is intended as a “race-only” application as it has no AIR pump fitting, will not fit an exhaust catalyst, will trigger the  410 and 420 CELs, and is not CARB certified.

After years of development and testing for performance, fitment, and durability, Black Halo Racing is excited to announce the Black Halo Racing Long-Tube Header that many have waited for is finally available and production has begun.  Over a period of two-plus years this header was tested on a few different RX-8s with similar performance in all cases.

The attached dyno sheet is from a 6-port/6-speed 2008 RX-8 with about 25K miles on it and using a BHR Ignition System as it’s only modification (installed well before the dyno test was performed), including still using the factory cat-back exhaust system. Typical rear-wheel horsepower gains were 20-25 rear-wheel horsepower, with additional engine torque being demonstrated as low as 2,000 RPMs, but actual total gains in power are dependent on the age/condition of each engine and the presence of other modifications.

Utilizing three 1-7/8″ primary pipes and a 3″ merge collector, this header balances easy installation, interference-free fitment, and the most free exhaust flow possible.  In addition, the CNC-milled engine flange has very smooth transitions from the rectangle exhaust ports to the round primary tubes.

The Black Halo Racing Long-Tube Header includes a 3″ midpipe outlets and all the gaskets and hardware needed for a comprehensive swap from your factory manifold A discounted option is available for those who already have a 3″ midpipe.

Mounts for the factory front and rear oxygen sensors are also installed and positioned in their OEM locations.

Due to the value of this part these headers are special order only and may take 4-6 weeks to be manufactured and shipped to us from BHR in the USA. Please remember you may need to allow up to this amount of time from order placement to arrival.

The Black Halo Racing Midpipe with High Flow Cat is a 3-inch pipe design with a single resonator (the design of which is exclusive to Black Halo Racing) that proves two resonators are not necessary to quiet down the Renesis and provide a great sound. This pipe does both with unmatched build quality and durability. By utilizing a resonator which has no internal packing it will retain its tone practically forever. Our midpipe also provides OEM fitment and will bolt up to the stock exhaust manifold as well as any cat-back exhaust system that uses stock mounting points.

A 3″ ceramic catalyst is in welded in to this version of the resonated midpipe for those concerned with exhaust emissions. This catalyst is not suitable for track use nor does it come with a warranty. If your factory catalyst has failed please be sure that your ignition system and your engine are in proper operating condition before ordering the optional catalyst installed on your midpipe.

All necessary hardware and gaskets are included.

Please allow up to 28 working days for delivery of this part.
