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.
Rear brake upgrade all done ✅ in time for Rotary Revival 🤙🏻 RX8 Upgrades supplied Auto EXE rear rotors , pads and lines Overhauled calipers , new wheel bearings now matches the front 🙌🏻
Trip from Sunshine Coast to Gold Coast was a blast ! Car feels so much better, so much more throttle response, so much cooler. Highly recommend changing Autoexe Type F radiator+KTS Suction Tube+ODULA Ram air 🫶🫶🫶🫶 ARD High speed starter motor makes cold start+hot start lightning fast. Supplied by RX8 Upgrades 🔥🔥
OHLINS MAS-MI00S1 Road & Track Coilover Suspension for Mazda RX8 (Series 1 & 2, 2003-2012)
I use the Ohlins coilovers on my RX8, which is mainly used for street use and I found the standard spring rates to be too soft in the rear but the fronts to be fine. I changed my rear springs to about 350lbs/in and it feels pretty good to me now.
Cooling hoses on an older RX8 deserve honest scrutiny. Original rubber degrades with heat cycling over time. On a car where coolant system health is non-negotiable, unknown-condition hoses are a real risk. SAMCO’s reinforced silicone hoses are manufactured from high-grade material. As a result, they hold shape, flexibility and sealing integrity across a far wider temperature range than OEM rubber. Because of that, they are a genuine upgrade for any RX8 cooling system refresh.
That makes them a sensible choice whether you are refreshing a single failed hose or working through the cooling system while everything is already apart.
The 13B rotary runs hot and demands consistent coolant flow. Silicone resists the swelling, cracking and hardening that eventually compromise aged rubber hoses. Moreover, it does not deteriorate at the rates rubber does under extended high-temperature cycling. Fitting Mazda RX8 silicone hoses therefore removes one variable from the cooling equation. That reliability margin matters on a rotary engine.
In addition, SAMCO hoses carry a distinctive appearance under the bonnet. They show a considered, well-maintained build rather than a patchwork of old rubber.
The SAMCO range covers both individual hoses for targeted replacement and full hose sets for multiple cooling connections in a single job. For example, if access is already open for a thermostat, water pump or radiator service, a full set makes practical sense. It eliminates the need to revisit the same area when a second hose deteriorates shortly after. Also, each product listing details the specific connections and components included. Check those carefully before ordering to confirm the right hose or set for your application.
Whether you are refreshing cooling hoses as part of a scheduled service or responding to a specific failure, these reinforced silicone hoses will still be in sound condition long after a like-for-like rubber replacement would need revisiting.
Samco produces hoses designed to fit the RX8 cooling system, but fitment can vary between individual products and series. Always check the specific product listing to confirm the hose or set matches your RX8 before ordering.
Silicone hoses are more resistant to heat cycling and age-related degradation than standard rubber, which matters on a rotary engine that runs warm. On an older RX8 with hoses of unknown service history, replacing them with silicone gives you a known-condition part that holds up reliably under repeated heat cycles.
Both options are available. Individual hoses suit a targeted replacement where only one section needs attention, while a Samco RX8 hose set makes sense when you are refreshing multiple hoses in one job. Check each product listing to see exactly what is included.
Cooling hoses on any older RX8 deserve inspection if the service history is unclear or the car has covered significant kilometres. Rubber hoses harden, crack and can collapse internally over time, and a cooling system failure on a rotary can quickly become a serious engine problem. A planned hose refresh during other cooling-system work is sensible preventative maintenance.
Yes, Samco RX8 silicone hoses are stocked and available for Australian owners through RX8 Upgrades. Browse the individual product listings to find the specific hose or set that suits your cooling-system work.
If one hose has deteriorated, the others are likely a similar age and condition, so replacing the full set while the cooling system is already opened up is the more practical approach. A Samco hose set can make this straightforward and avoids having to revisit the job shortly after.
Coolant hose replacement on the RX8 is within reach of a competent home mechanic with basic tools, though the process requires draining the cooling system and careful reassembly to avoid air pockets. If you are not confident working on cooling systems, having a workshop complete the fitment is a reasonable choice.
