AUTOEXE Premium Cat-Back Exhaust Muffler for Mazda RX8 (Series 1 & 2, 2003-2012) AUTOEXE Premium Cat-Back Exhaust Muffler for Mazda RX8 (Series 1 & 2, 2003-2012)

Just installed my spanking new Autoexe Stainless Muffler, and here's a short take of my initial impressions: The Autoexe catback is lovely - very unique 2 box design and the tips are the tapered kind (ie cut at an angle) each lasercut with the Autoexe logo. Very nicely polished midpipe which connects beautifully (and easily) with the exhaust outlet. Most importantly, the exhaust tips have a perfect visual alignment, unlike other exhausts i've seen where one tip protrudes out more than the other. The Autoexe definitely doesn't have this problem. Also, the 2 box design has a lower profile than stock. Previously, i used to scrape and even dent the exhaust box when clearing humps or even parking - not so with the Autoexe. The Autoexe performs really well, at least on my AT. There is a noticable increase in low end torque, and the car just feels substantially lighter. Revs are much more responsive, and the slight lag felt when launching the car seems to have melted away. Linear acceleration is also much faster (at least across 1st 3 gears), and i'm reaching 120-130kmh much faster on 2nd gear alone (NB mine is the 4spd AT). I'm very pleased with the low-torque gains on the Autoexe - finally i have that slight 'lurch' from start which the manuals seem to have, but the ATs don't. The Autoexe starts off idle with a really low, bassy growl. When first installed, it was barely audible, but sounds louder now. In time, the db will increase to an extent. On higher RPM revs, exhaust sounds deep and wet, and def not those shrilly Remus' we hear on the expressways from time to time. Installation was a breeze, and took under an hour at Monster Garage at Ubi, who's the only authorized dealer in Singapore, so these guys know their stuff. The torque/hp improvement was a shocker esp on low end, esp when mine's an AT. I've heard of bros installing Fujitsubos and HKSs that have either no or negative benefit. In this respect, I'm mighty pleased with the Autoexe. Sound is not loud, but a soft low bassy growl when idle, which develops into a mature wet sound at higher revs.

Project Mu brake pads for the RX8 are Japanese motorsport compounds engineered for consistent bite, heat resistance and progressive feel. Developed on the track circuits of Japan, that same engineering discipline carries through to their road and performance street grades, covering a range of compounds suited to the rotary’s lightweight chassis and high-revving character.

As a result, RX8 brake pads from Project Mu are a genuine upgrade over worn or budget replacements. For a lightweight, high-revving platform like the RX8, the quality of the friction material under your foot is not a detail to overlook.

Pads, Rotors and Discs, Choosing the Right Component

The Project Mu range for the RX8 covers more than just pad compounds. Owners researching Project Mu RX8 brake rotors will find that matching a quality rotor to a quality pad delivers more consistent bite, and a matched pairing extends service life. Mixing premium pads against a worn or mismatched disc undermines both.

Brake discs and rotors are the same component by two common names. Whether you are searching for RX8 brake discs or rotors, check each listing for the part number, compound grade and application.

Why Project Mu Compounds Deliver

  • Motorsport-derived compounds: Project Mu compounds are developed under real racing conditions in Japan. They are then refined into street grades that deliver predictable, progressive braking. As a result, you get real-world performance without the cold-bite harshness of a pure track pad.
  • Consistent feel to the redline: The RX8’s rotary engine encourages use of the full rev range. Because of that, late-braking confidence into corners is part of what makes the car rewarding. Quality friction compounds also keep pedal feel consistent when the brakes are working hard.
  • Matched rotor and pad combinations: Running Project Mu pads against a Project Mu rotor means the friction pairing is engineered together. Therefore, bedding-in guesswork is reduced and both components reach their full service life.
  • Available in Australia: Australian stock means you are not waiting on international freight for a core safety component. However, check each listing for current availability.

Building Your RX8 Brake Upgrade

A brake upgrade on the RX8 is most effective when the whole system is considered together. For example, if your rotors are due for replacement, sourcing pads and rotors from the same quality manufacturer is the straightforward approach.

For owners fitting new RX8 brake pads as the first step, confirm rotor condition before installation. That ensures you get the full benefit of the upgrade from the first drive. Review individual product listings for compound recommendations, application notes and fitment details before ordering.

Frequently Asked Questions

What Project Mu brake products are available for the RX8?

Project Mu produces brake pads, rotors and brake discs suited to the Mazda RX8. Each product is listed separately, so check the individual listing for the exact component type, compound or specification before adding anything to your shortlist.

Do Project Mu brake pads suit both Series 1 and Series 2 RX8 models?

Fitment can vary between Series 1 and Series 2 RX8 models, and between front and rear axles. Always confirm the vehicle application details on the individual product listing before ordering to make sure you are selecting the correct pad for your car.

What is the difference between Project Mu brake pads and brake rotors?

Brake pads are the friction material that clamps against the rotor to generate stopping force, while rotors (also called brake discs) are the spinning metal surfaces the pads contact. They are separate components sold individually, so confirm which part of your braking system you are replacing before ordering.

Are Project Mu brake pads a direct replacement for OEM RX8 brake pads?

Project Mu pads are designed as direct-fit replacements that slot into the factory caliper without modification. Compound choice will vary by intended use, so review the individual product details to match the pad specification to your driving style and requirements.

Should I replace brake pads and rotors at the same time on my RX8?

Fitting new pads to a heavily worn or scored rotor can reduce braking consistency and shorten pad life. If your rotors are near minimum thickness or show uneven wear, replacing both together gives the new pads a clean, flat surface to bed in against and helps restore predictable braking feel.

How do I choose the right Project Mu brake pad compound for my RX8?

Compound choice depends primarily on how and where you drive. Street-focused compounds prioritise low dust, quiet operation and cold-bite for daily use, while track or motorsport compounds need heat to reach their operating range and can feel inconsistent on a cold commute. Check the operating temperature range and intended use on each individual product listing.

Is Project Mu a reputable brand for RX8 brake upgrades?

Project Mu is a well-regarded Japanese brake specialist with a long history in both motorsport and road applications. Their products are a recognised choice among rotary owners seeking a step up from standard brake components in terms of feel, consistency and fade resistance.
