2007-2013 Mazdaspeed 3 Downpipe

Get maximum turbo performance and dramatically increase torque with the Mazdaspeed 3 Power Series Downpipe. The CorkSport Mazdaspeed3 downpipe was expertly designed to replace the restrictive element in the Mazdaspeed 3 stock downpipe

The CorkSport Advantage

Fitment Choices:

Pick the 65mm flange for stock fitment (it will also work with all aftermarket exhausts), or 80mm flange for the CorkSport Cat Back exhaust and true 3" piping. Either way, mandrel bent piping is used to create smooth exhaust flow for dramatic increases in power.

Improved Power:

With just an intake installed, you can gain up to 50 HP more by adding the long catted downpipe or short downpipe and race pipe.

CorkSport Short Downpipe:

Replaces just the downpipe section but not the racepipe for a cost-effective solution that works with the stock racepipe, or aftermarket. For lasting corrosion resistance and reduced heat transfer to the engine bay, the CorkSport MS3 downpipe uses polished 304 stainless steel and features TIG welds that offer superior arc and weld puddle control for a cleaner appearance and precise weld bead control

CorkSport V2 Long Catted Downpipe

Our long downpipes now use our new “modular” system to improve flow, enhance fitment, and simplify installation in your MS3 engine bay. The design utilizes a cast stainless steel bellmouth with a v-band connection to 3” stainless steel piping. A 300 CEL high-flow cat is included to help keep emissions in check with minimal drawbacks. The long downpipe replaces both the OEM downpipe and racepipe sections.
