Our Civic Type-R Decat Downpipe replaces the standard restrictive downpipe and catalytic converter with a stainless steel, 2.5″ 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 and improving throttle response.
Manufactured from T304 stainless steel
TIG welded, CNC machined flanges
Please note: sold for off-road/track use only, will not pass an MOT test while fitted.
