Mazdaspeed 6 Downpipe V2

The CorkSport Advantage

Performance Focused:

The CorkSport V2 Downpipe drastically improves exhaust flow compared to the restrictive OEM downpipe. This results in approximately 26whp & 32twq of power increase on a stock turbo car. Even larger gains could be expected for cars with an upgraded turbo.

Fitment Inspired:

Knowing most Mazdaspeed owners are the DIY type, we aimed to make installation and fitment much easier with the V2 design. The modular design with a separate cast bell mouth and v-band connected pipe section does just that.

With the 2-piece upper and lower sections of the downpipe, all downpipe nuts are now easier to access as you do not have the lower section in the way while tightening. This allowed for easy stud & nut access with cutouts designed to fit sockets & wrenches. Lastly, should you ever need to remove the downpipe or turbo for maintenance, the bellmouth portion can stay attached to the turbo! Disconnect the v-band clamp and remove the lower DP section from the exhaust.

Catted & Catless:

The CorkSport V2 Downpipe is designed to fit an upgraded OEM, 3” or 80mm exhaust that uses the OEM style flange for an easy install with your existing pipes. Offered in catted and non-catted setups; both are for race use only and are not street legal in areas with emission controls. The catted setup uses a high-flow 3-way metallic foil 300cel CAT with a 4-inch outer diameter.

Materials & Manufacturing:

At the turbo side, the CorkSport modular downpipe uses a cast 304 stainless steel bell mouth for strength, reliability & simplicity. The piping uses a CNC machined V-band flange TIG welded to mandrel bent 304 stainless piping. CNC machining ensures a leak-free seal, TIG welds ensure high strength, and mandrel bend ensures smooth exhaust flow.

Included with your modular 3” downpipe is everything needed for installation. This includes a stainless v-band clamp for the bellmouth to DP connection, new downpipe mounting studs & lock nuts, a new flange gasket at the mid-pipe, and even an O2 sensor harness extension. We’re most proud of our custom MLS downpipe gasket included with each kit. We port-matched it to the DP bellmouth & CST6 to ensure no flow restrictions whatsoever!
