Designed to replace the restrictive catalyst in the stock downpipe and deliver improved exhaust flow for significant power gains, noticeable improvements in turbo response time, and reduced backpressure, CorkSport is pleased to announce a new high-flow catalyst option for their popular CorkSport Mazdaspeed 3 Downpipe.
The CorkSport Mazdaspeed 3 Downpipe is constructed from polished 3 Inch or 2.5-inch 304 stainless steel piping for lasting corrosion resistance and reduced heat transfer to the engine bay. Unlike many downpipes on the market, the CorkSport downpipe uses a unique divorced wastegate design that will reduce boost spikes and exhaust flow disturbances due to waste-gate operation.
The new catted version of the CorkSport Mazdaspeed 3 Downpipe provides gains of up to 21 WHP and includes a high-flow spun metallic 200 cell catalyst and three O2 bungs to allow for the addition of EGT or other sensors.
Our new catted downpipe option incorporates all of the popular features of our current Mazdaspeed 3 downpipe with the addition of the high-flow metallic flexible catalyst for cleaner emissions. We have included our popular CorkSport Mazdaspeed 3 Racepipe in the catted option to provide even more horsepower and torque to your exhaust set-up.
The CorkSport Mazdaspeed 3 Catted Downpipe is a direct bolt-on replacement for the restrictive factory downpipe and attaches seamlessly to the factory or an aftermarket cat-back exhaust set-up using a factory-style donut.
In addition, we’ve added the modular bellmouth to the design. This development provides a vast improvement during installation. The fitment is so much better with a modular v-band-connected bell mouth. You no longer need to fight the downpipe while trying to tighten it to the turbo!
The new optional catted downpipe is available for purchase from CorkSport’s online catalog at https://www.corksport.com/corksport-mazdaspeed-3-downpipe.html
