I just got off the horn from Flyin Miata, order the stainless steel downpipe/catalytic. Should be good for another 15hp! Woo-Hoo!! This will be one of the biggest mods I have ever made to my Miatas. So far I have only done a couple little things to the Mazdaspeed to make it my own.
Baco, any plans for engine mods to your MSM??
