HKS Hi-Power Cat-Back Exhaust with Titanium Tip for Mazda RX8 (Series 1 & 2, 2003-2012) HKS Hi-Power Cat-Back Exhaust with Titanium Tip for Mazda RX8 (Series 1 & 2, 2003-2012)

I'm running it with the stock cat, and it's relatively loud, but not obnoxious. I haven't heard it compared to the borla though. My wife can hear me from about a quarter mile a way if she's outside and I get on it. At idle and just cruising, it's fairly tame. I haven't had any trouble with it or any unwanted attention. It is not raspy at all and doesn't bellow as much as say a Greddy SP2. It's actually only a tad louder than an SP2, so if you've heard one, you can get an idea for sound.

BEATRUSH is a Japanese manufacturer with a focused approach to underbody engineering. Their Series 1 RX8 undertray components reflect that precision. Each part is designed to suit the specific mounting points and underbody geometry of the Series 1 car. As a result, they fit correctly and stay put. This is not an afterthought, but a purpose-made solution for a model with real rotary heritage worth preserving properly.

Why the undertray matters on a Series 1 RX8

The underside of an RX8 is one of the first areas to suffer from age, impacts and missing hardware. For example, a correct-fitting underbody panel restores factory-level coverage. That matters for aerodynamic consistency, road debris management and overall underbody presentation.

For owners building a clean, well-considered RX8, leaving the underside unaddressed is a visible compromise. Therefore, BEATRUSH parts give that area the same attention you’d give the rest of the build.

Series 1 RX8 undertray ordering checklist

  • First, confirm the component is specifically listed for the Series 1 RX8. Series 1 and Series 2 mounting arrangements can differ.
  • Also, inspect existing undertray mounting points and hardware condition. Worn or broken clips affect fitment of any replacement panel.
  • Next, identify whether you need a full RX8 engine undertray or a smaller underbody cover section. Each listing specifies its exact location and coverage area.
  • Finally, consider how the new piece sits alongside adjacent underbody components to ensure a continuous, neat fit.

Frequently Asked Questions

What does a BEATRUSH undertray actually do for an RX8?

A BEATRUSH undertray covers and protects the underside of the engine bay area, keeping road debris away from components and contributing to a tidier, more cohesive underbody. On a car like the RX8 where underbody condition is easy to overlook, a properly fitted undertray also makes subsequent maintenance and inspection cleaner and more straightforward.

Do BEATRUSH undertrays fit both Series 1 and Series 2 RX8 models?

The undertrays in this BEATRUSH range are specifically suited to Series 1 RX8 models. Confirm fitment on the individual product listing before ordering, as Series 1 and Series 2 vehicles differ in underbody geometry and mounting points.

My original RX8 undertray is missing or damaged. Is a BEATRUSH replacement a direct fit?

A BEATRUSH undertray is designed to suit the Series 1 RX8, making it a relevant option when the factory piece is missing, cracked or worn. Before ordering, inspect the condition of your existing mounting points and hardware, as damaged attachment points will need attention regardless of which undertray you fit.

What should I check before fitting a new undertray to my RX8?

Check that the undertray matches your specific Series 1 RX8 application, review the mounting arrangement described on the product listing, and inspect all factory attachment points for damage or corrosion. Consider how the undertray sits alongside any other underbody components already fitted to your car.

Why choose a BEATRUSH undertray over a generic or second-hand replacement?

BEATRUSH is a Japanese performance brand known for precision-engineered underbody and chassis components. A new BEATRUSH undertray gives you a known-condition part designed specifically for the RX8, rather than a worn used piece of uncertain history or a generic panel that may not align correctly with factory mounting points.

Is the BEATRUSH undertray relevant to cooling on the RX8?

An undertray can influence underbody airflow management, which plays a role in how air moves beneath and around the engine bay. Review the individual product listing carefully to understand the specific function of each BEATRUSH undertray option, and consider it within the context of your car's wider cooling and underbody setup.

Are BEATRUSH RX8 parts available in Australia?

Yes, BEATRUSH parts for the RX8 are available through RX8 Upgrades in Australia. Check individual product listings for current availability and confirm exact fitment details for your vehicle before purchasing.
