The core of a good turbo system. Now with standard Inconel studs!

Made in the USA

Exclusive to Flyin' Miata



Want to build your own turbo system? Here's the start you need: the solid and proven FM turbo manifold, outlet casting and downpipe. Shop around, and you'll find this is the best deal going.

The downpipe is CNC-bent stainless steel with bungs for both the stock O2 sensor and a wideband. Like all our other downpipes, it has a lifetime warranty. The 2.5" downpipe will bolt to a standard Miata midpipe flange, the 3" one uses a different flange and will either require a custom exhaust or our Flyin' Miata 3" unit. The 3" exhaust upgrade includes a full exhaust system right to the tailpipe.

The manifold and outlet are the same ones we've used on 450 rwhp turbo Miatas. They're cast and machined in the US for the highest quality and consistency, and are designed to fit turbos with a T2/T25 flange. Older sleeve bearing turbos will require a couple of holes in the outlet to be enlarged.

Inconel studs are standard to give the best reliability under hard track use.

No EGR pipe is included on 1.8 manifolds although the manifolds are machined for a fitting. Factory 1999-00 EGR pipes can be used on any 1999-05 cars and we offer a custom EGR pipe for 1994-97 cars. If you're not going to use it, we carry a plug for the EGR.

  • The downpipe may or may not fit with your automatic transmission. We've seen mixed results. We cannot guarantee fitment with an automatic.
  • Of course, it's compatible with any of our other turbo parts. Hard water and oil lines? An intake setup? A complete intercooler system? Heck, we can even supply the turbo if you'd like.

    Quality pieces and FM does not dissapoint.
    Overall a quality product. Although there were a couple minor concerns. On the upper turbine outlet pipe one of the holes are misaligned and require to be drilled out or widend. Maybe I just got a slightly defective batch. No big deal. I also I feel like im missing a couple gaskets. Such as the manifold outlet to turbo and upper turbine pipe to lower downpipe. In the end im happy with FM's product and would not hesitate to purchase again.

    Note from FM: The holes match the Garrett pattern for ball bearing turbos. Non-Garrett turbos may have slight variation in the bolt placement, and sleeve bearing turbos will require some modification to the holes. We do not recommend a gasket between the manifold outlet and turbo or between the two halves of the downpipe, which is why these are not included.
