Springfield Dyno Spec Miata Exhaust

Even after 4 years, this is THE EXHAUST to have. We continue to develop, tweak and dyno test new systems and this one is still the system to beat.

This system continues to produce 2hp and 2lb. of torque more than the expensive motorcycle style systems that are available from other sources.

This system also produced over 4hp and 4lb. of torque more than the Mazda Comp system.

It also weighs 15.5 lbs compared to the 19.5 for the Mazda comp.

The sound level is comparable to the Mazda comp exhaust and much quieter than a "JD style" exhaust.

It has all mandrel bends which are much better than the crush ends you get at a muffler shop.

Developed and Dyno'd by Sam Henry of Springfield Dyno.

Now being run by top runners such as Drago, Foss and others. It's what we're running.

Sorry, free shipping does not apply, so cost is $275 + $20 shipping, it will show up as $295 and no additional shipping costs.
