Our Mazda RX-8 Decat Downpipe replaces the standard restrictive downpipe and catalytic converter with a stainless steel, 2.75" one-piece item. Increasing the bore of the downpipe and replacing the restrictive catalytic converter allows the exhaust gasses to flow much more freely, increasing the power output of the engine.
Manufactured from T304 stainless steel
TIG welded, CNC machined flanges
Gaskets and bolts included
Please note: sold for off-road/track use only. Will not pass an MOT emissions test.
Fits Mazda RX-8 2003-2009 models.
