About the NB 2.25" Flyin' Miata midpipe and catalytic converter
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 (ability to pass an emissions test), everything else is covered for life. 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.
This resonated midpipe (2.25" diameter) work great for both naturally aspirated and Stage 1 turbo Miatas. 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.
Not compatible with the 2004-05 Mazdaspeed turbo car.
As with all of our catalytic converters, this cat is emissions-certified. Specifically, it's EPA-approved for this application. Please note that these are not CARB legal and we cannot ship them to California. They're also not legal in states requiring CARB cats. That's California, Colorado, New York, and Maine for 2001+ cars.
