Flyin' Miata 2.5" resonated turbo midpipe and catalytic converter (NB chassis)

100% stainless steel tubing replacement for the midpipe. Our pipe includes a three-way catalytic converter and has a resonator to give the perfect exhaust note. It also includes a slip joint to make it easy to get the perfect fit. 5 yr/50,000 mile warranty on the 300 cell ceramic catalytic converter housing and 25,000 miles on the internals, lifetime warranty on everything else. Warranty details. Fits with all factory bracing.

Not compatible with the stock muffler on automatic Miatas, although you can use both this pipe and our turbo muffler on one.

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 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. There have been a few reports of leaks when used with the Roadstersport exhaust. 

Not compatible with the 2004/05 Mazdaspeed MX-5.

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 (currently) California, Colorado, New York, and Maine for 2001+ cars.
