3" downpipe for FM turbo systems

Lower downpipe section, designed to mate up to our turbine outlet casting. Made of CNC bent stainless steel with a lifetime warranty. 3" diameter after the initial flange. Includes a sensor bung for a wideband. The slip joint in the middle allows for fine-tuning of fit.

The outlet flange on this downpipe is a triangular 3" style and is not compatible with most exhaust systems. You will either need a Flyin' Miata 3" exhaust system or you're going to have to build a custom setup.

The NA8 version will fit a NA6 that has received a 1.8 conversion, but not cars that still run the 1.6.

The NB unit will fit a MSM that has been fitted with one of our Garrett turbo conversions and runs a complete NB exhaust. It is not compatible with the stock MSM turbo or a MSM-specific exhaust.

This downpipe should not affect the status of emissions certification on its own, but the exhaust you attach it to (specifically the cat) will likely be a factor.
