AUTOEXE Rear Side Cowl Set for Mazda RX8 (Series 2, 2009-2012)
Autoexe is a reputable aftermarket brand for Mazda. I actually swapped my crackced accordion one for this same one. GOod stuff.
The entire process was seamless and the wheel itself is phenomenal. I really don't know how I'd improve it, other than the stitching color if my car was other than SRC. They don't seem to offer anything but red stitching. I might not have chosen the red centerline marker, but it's growing on me. I'm very pleased overall.
GENUINE MAZDA OEM Intake Solenoid for Mazda RX8 (Series 1 & 2, 2003-2012)
Happy 8's day people! For you series 2 owners, here's the easiest way I found to change these little suckers. RX8 Upgrades providing the genuine goods as always. Remove the air box/ CAI, remove throttle body and remove the top part of the UIM only, this will get you easy access to the solenoids. Now you could remove them from this point, but removing the oil filler neck along with the vacuum chamber the solenoids mount to makes it FAR easier to change them. This whole job can be done in an afternoon for a mechanically minded person. On reassemble, don't forget to place the vacuum reference back onto the bottom of the manifold (has a green check valve) otherwise no valve will work. Reassemble and enjoy. PN is KL01-18-741 for those chasing the part
Huge shout out to RX8 Upgrades for all the bling bits he's supplied so far for my series 1 Steering wheel , GReddy Radiator , Odula intake , Extractors , OMP sheild , Brass gear stick bush , Alternator , GReddy pulley set , New gear stick boot , Magnetic sump plug with a lot more to come ! One of the nicest guys to deal with as well for parts and knowledge on Mazdas is next level !
More cool parts from https://rx8upgrades.com.au/ for the project car number two 🙌🏻 KTS coilovers front and rear AutoEXE two piece rotors front and rear with AutoExe pads Project PMU braided lines in charcoal Raypower 20mm bolt on spacers Fully rebuilt calipers with new pistons One corner done three more to go 🤙🏻 Thanks RX8 Upgrades nothing but the best forget the rest 🏁
An RX8 cat back exhaust covers everything behind the catalytic converter: mid-pipe, resonator, rear silencer and tip. This range extends further, covering manifolds and high-flow cats for owners sharpening the sound, flow and configuration of their rotary build at every stage of the system.
The 13B-MSP’s combustion cycle produces exhaust pulses at a different rhythm to a piston engine. Because of this, the system’s design, diameter and flow characteristics genuinely influence how the car breathes and sounds across the rev range. Choosing the right rear section changes the character of the car without touching the front of the system. It is, therefore, one of the most accessible upgrades in a performance exhaust build.
A rear section is rarely the whole story. For a more complete setup, an RX8 exhaust manifold upgrade addresses the primary collection point directly off the rotor housings. That is where the gains from improved flow begin. In addition, pairing it with an RX8 high flow catalytic converter and a well-matched cat-back section gives you a system working together from engine-out to tailpipe. This approach is especially worthwhile if the stock exhaust is original and ageing. For example, worn sections rob flow and degrade sound before the obvious signs of failure appear.
Pipe diameter is also worth considering at every stage. A 3 inch RX8 exhaust mid-section or cat-back suits builds chasing a freer-revving character and a more assertive note at higher revs. Meanwhile, a slightly smaller diameter may preserve mid-range response on a lightly modified road car. The right choice depends on what else is fitted and how the car is used. Always read the individual product descriptions for the manufacturer’s stated intent.
Exhaust fitment across the RX8 range is not always interchangeable. For example, connection diameters, mid-pipe routing and rear bumper clearances can differ between early and later models. Some products are specifically engineered for the RX8 Series 2 facelift; others suit the Series 1 body.
Every listing on this page states its intended fitment. Therefore, confirm your car’s series and production year match the product’s application before ordering. If you’re unsure which series you own, the easiest reference is Mazda’s RX8 information page.
Browse the listings below and read the fitment notes carefully. Build your shortlist around the exhaust sections your car actually needs. Finally, whether you’re starting with a single rear section or speccing a full RX8 cat back exhaust alongside a manifold and high-flow cat, focus on the stated diameter, connection style and intended application. The right fit for your specific build and budget matters more than a label.
Cat-back refers to the section of exhaust system that runs from the catalytic converter rearward to the tailpipe. On an RX8, replacing this section changes the exhaust note and rear-section flow without disturbing the front pipe, manifold or catalytic converter. It is one of the most accessible ways to refine the sound and character of the car.
Not all cat-back systems are interchangeable between Series 1 and Series 2 RX8s. Connection styles and system layouts can differ between the two generations, so it is important to confirm the stated model application on each individual product listing before ordering.
A cat-back system can be fitted independently of the manifold and catalytic converter, provided the connection at the cat outlet is compatible. Many owners start with the cat-back section and plan manifold or high-flow catalytic converter upgrades as a separate stage. Checking connection details across components before purchasing keeps later upgrades straightforward.
A high-flow catalytic converter reduces restriction ahead of the cat-back section while retaining the emissions equipment. On a rotary engine that relies on exhaust scavenging, reducing backpressure through the full system rather than just the rear section gives a more consistent result than a cat-back upgrade alone.
A 3-inch system suits builds where the full exhaust path has been opened up to match, but on a standard or mildly modified street RX8 it can produce excessive drone and may not suit daily use. Consider your intended driving environment and the other components already fitted before committing to larger-diameter pipework.
Either order can work depending on budget and priorities, but many builders fit the cat-back first for the immediate change in sound, then address the manifold as part of a broader front-to-rear system plan. Choosing components with compatible connection points from the start avoids the need to revisit fitment when adding the next stage.
A cat-back replacement on an otherwise standard RX8 does not typically require a retune, as it sits downstream of the oxygen sensors. More comprehensive changes involving the manifold or catalytic converter may warrant a review of the fuelling map, particularly on modified engines.
