Very happy.
Fitment was no problem at all with butterfly brace. Very adjustable if necessary but didn't require much fiddling. Sound is great and accurately described. Deeper, a little louder, but tasteful. The only drone I hear is on initial startup for a minute or so but who cares. On the road there's nothing. Car already feels less restricted at minimum boost levels compared to 2.5" DP and otherwise stock system, will be tuning soon and expect good numbers.

Sounds Great. Poor Fitment.
97’ Miata; FM cast turbo manifold; GT2560r (sourced used); FM cast turbine outlet; FM full 3” exhaust. The exhaust doesn’t clear the transmission bell housing and rattles with engine movement.

Note from FM: JMH, please contact us.

Probably the best Miata exhaust there is
fitted with FM2 kit and the butterfly brace. I was skeptical about how well a 3" system would fit along with the butterfly brace. Really pleased with how easily everything lined up. Also! with a turbo, this system is NOT loud and Honda-y at all. Very mild and exactly what I wanted.

Exhaust is good, cat is bad.
Fitment of the kit is great. My catalytic converter failed (The core came loose) after 3000 miles. Was denied warranty on it due to a surface scratch on the cat. FM did give me a partial store credit for it though.

I have also done a T2 transmission swap. The 3" downpipe will clear the T2 transmission with some light trimming of the T2 bell housing. The cat and first flange will not however.
