Fresh Mazda RX8 exhaust hangers, six pieces, steady the system and cure the rattle-and-shift that worn rubber mounts cause.
$120
Mazda RX8 exhaust hangers wear out quietly. The symptoms show up later: a rattle over bumps, a mid-pipe that has crept out of place, or clunking on cold starts. This APEXi six-piece strengthened rubber set replaces all the critical support points in one pass.
It covers four muffler positions, one mid-pipe position and one catalyser position across Series 1 and Series 2 cars. Strengthened rubber means firmer support than fatigued OEM mounts deliver.
That matters on a rotary, where exhaust heat cycles and vibration work rubber harder than on a conventional piston engine.
For RX8 enthusiasts, the change is felt immediately: the exhaust sits still under hard acceleration and rattles disappear. Alignment holds after an exhaust upgrade or service.
Replacing all six supports together means no tired mount is left to undo the work.
If an aftermarket system is next on the list, pair these Mazda RX8 exhaust hangers with the HKS Hi-Power Cat-Back Exhaust with Titanium Tip for a complete exhaust refresh. Add the GP SPORT Exas High-flow Power Catalyser when the catalyser support point is being renewed. For earth continuity after any exhaust work, the ODULA Racing Exhaust Earth Strap Set is a sensible addition. Learn more about the brand at the APEXi official website.

The APEXi Strengthened Exhaust Hanger Set includes six pieces in total, packaged as three two-piece packs. They cover four muffler positions, one mid-pipe position and one catalyser position, so every critical support point on the RX8 exhaust system is renewed in a single job.
Yes. The APEXi set is designed for direct fitment across the full RX8 production run from 2003 to 2012, covering both Series 1 and Series 2 without modification.
These strengthened rubber hangers suit both standard and upgraded exhaust systems. If you are fitting or have already fitted a performance cat-back or high-flow catalyser, these hangers will carry across and keep the new system properly located.
The rotary engine subjects exhaust mounts to more frequent and intense heat cycles than a conventional piston engine, combined with the vibration characteristics of the 13B. This accelerates the softening and fatigue of the original rubber, which is why symptoms like rattle, mid-pipe creep and cold-start clunk tend to develop over time.
Common signs of worn exhaust hangers on the RX8 include a rattle over bumps, clunking on cold starts, or a mid-pipe that has shifted out of its original position. If any of these are present, inspecting and replacing all six mounts at once is the most effective fix.
Replacing all six together is the recommended approach. If one mount has fatigued, the others have experienced the same heat cycles and are likely in a similar condition. Leaving old mounts in place risks rattles returning quickly and undoing the work of a fresh install.
Exhaust hanger replacement is generally a straightforward job requiring basic hand tools and safe vehicle access underneath. The six-piece set covers all support points, so the entire system can be refreshed in a single session rather than returning to finish the job later.
