Mazdaspeed downpipe/catalytic converter upgrade

Replace the restrictive and heavy downpipe on your Mazdaspeed with this 2.5" stainless steel version. When combined with our Mazdaspeed exhaust, it offers noticeably faster spoolup and a good increase in power. We measured a 23 hp and 26 lb-ft increase on our dyno. If Mazda had delivered the car like this from the factory there would be a lot less interest in aftermarket upgrades! An extremely popular upgrade for Mazdaspeeds.

Beautifully made out of stainless steel with polished flanges, this is a long-lived upgrade. So long that we offer it with a lifetime warranty. It`s also 7.2 lbs lighter than stock as an extra bonus.

This downpipe is available with a catalytic converter that meets federal emissons standards. Unfortunately, it is not legal for use in California and cannot be shipped there.

5 year/50,000 mile warranty on the catalytic converter body, the internals (and ability to pass an emissions test) are covered for 25,000 miles, everything else is covered for life. Fits the Mazdaspeed with stock turbo only.
