Our take on the MagnaFlow MX-5 Midpipe with CARB Catalytic Converter for Miata MX5-NC 2006-2015
A CARB-legal replacement midpipe for the 2006–2015 Mazda MX-5 Miata, built with MagnaFlow around a full-length catalytic converter. The 2.5-inch mandrel-bent stainless pipe flows more than the stock piece, which has smaller diameter and crush bends, and its flanges match RoadsterSport mufflers for a bolt-on swap with no cutting or welding. Owners report stronger low-RPM torque, quicker pull to redline, a deeper idle burble with no drone, and about six pounds less weight than stock. It is the pick for California NC Miata owners who want a legal cat and a freer exhaust in one part; the main knock is that it costs more than a plain replacement midpipe.
- CARB-legal converter (EO D-193-130) for 2006–2015
- Full 2.5-inch mandrel-bent flow, larger than stock
- Flanges bolt directly to all RoadsterSport mufflers
- Stainless steel with no cutting or welding needed
- About six pounds lighter than the stock midpipe

What reviewers say
NC Miata owners describe a clear gain in low-RPM torque and a faster pull to redline, with a deeper idle and deceleration burble and no drone. Most call the sound a proper sports-car note under hard acceleration. The recurring complaint is the higher cost than a plain midpipe.
- Low-end torquePraisedOwners say it pulls out of corners better and no longer waits until 4000 RPM for power.
- Exhaust soundPraisedA deeper idle and burbling on deceleration, loud only under hard acceleration and free of drone.
- WeightPraisedAbout six pounds lighter than the stock midpipe.
Questions and answers
- Is this midpipe legal in California?
- Yes. It carries CARB EO D-193-130 and is compliant for 2006 through 2015 MX-5 models only.
- Will it fit my RoadsterSport muffler?
- Yes. The flanges are made to match all RoadsterSport mufflers, and it bolts on without cutting or welding.
- How does it compare with the stock midpipe?
- It uses a full 2.5-inch mandrel-bent pipe instead of the stock's smaller pipe with crush bends, and it weighs about six pounds less.
- Does it add power?

- Will it drone on the highway?
- Owners say no. The note is deeper at idle and under acceleration but stays quiet at cruise.
