MAZDA RX-8 / R3 "Pettit Racing" Exhaust System (Cat-Back)


  • £82500 (inc. VAT)

Pettit Racing have worked with Milltek Sport, one of the UK's premiere exhaust specialists to create a full and modular exhaust system for the RX8.

Featuring huge 4 inch beautifully crafted tips, sculpted to fit the curves of the RX8s rear valances, and a twin box muffler system for elegant looks, great sound and weight saving, this full 3 inch system has been carefully engineered to give a slightly more aggressive sound than the Racing Beat cat-back system, but with none of the in cabin 'drone' on cruise, from louder systems.

Very civilised in cabin, and when cruising, but the system really opens up under more aggressive driving. 

The modular nature of the system not only allows easy adjustment for fit, but easy customisation. You can simply remove the cat section and replace it with the cat delete pipe, while keeping the entire cat back and resonated sections in place. Not only that, but the straight through slip system allows a totally free flowing system, whereas the OEM flange introduces an unavoidable restriction. Weight savings are 2kg over OEM for the cat-back alone, and with the resonated hi flow cat as well, 7KG is saved over OEM.




The 2009+ R3 model is a slightly different fit.The R3 model Pettit Racing catback is available NOW. Make sure you specify an R3 system when ordering!
