Replacement midpipe for more power on normally aspirated cars. All stainless steel, lifetime warranty and a high-flow cat.

A full stainless replacement for the restrictive factory midpipe and catalytic converter. The 300-cell ceramic catalytic converter has a 5 yr/50,000 mile warranty on the housing and 25,000 miles on the internals, everything else is covered for life. Warranty details. Our midpipe includes a slip joint to make it easy to get the perfect fit and to cut down on your shipping costs. Works with all factory undercar bracing.

Help us recycle and get $20 back if you ship us your old original equipment catalytic converter. It must still have the ceramic core in it, doesn`t have to work. OE cats only. To save on shipping, you can cut the cat out of the midpipe.

Naturally aspirated Miatas should use this 2.25" version which is resonated. Miatas with aftermarket turbos should use our non-resonated 2.5" unit. Not compatible with the stock rear muffler on automatic cars. We do not recommend using this midpipe with a supercharger and aftermarket header due to sound levels.

The FM midpipe flange and the factory muffler flange use a different gasket in order to seal the exhaust system. We are aware the seal is not perfect when used with factory parts and we found the best seal can be obtained by using the factory donut gasket. This imperfect seal will not be an issue with a Flyin' Miata muffler. Please note that these are not CARB legal and we cannot ship them to California.

Not compatible with the 2004-05 Mazdaspeed turbo car.
