How hard to fit a FM downpipe from a 99 car onto a 93?
 

That guy that has a FM downpipe (without the cast upper part) and a exhaust for sale for a 99 miata. Wouldent I just need a 90 degree bend at the top to get it close? I can do alittle cutting and welding if I have to, but would it be near what I need?

Not shure, but the FM sets are simular except the manifold and DP.
(difference between 1.6 and 1.8)
The Downpipe is larger on the 1.6 (smaller cat)(Keep the cat that belongs to the dp)
But the cast turbo to DP will be the same.

The 99 and up use a diff exhaust system and as a whole they can be fitted to an NA, but will require some welding as the hangers on the exhaust don't match...

Ask FM they would know.

You are smart my friend!
