$225 shipped to the lower 48 states
I'm not positive the brand of DP but close as I can figure it is a Mazda Racing or Turbo Tony. TD04h flange with two O2 sensor bungs and a stainless flex section to make mounting a lot easier.

It was a mess when I got it but another MT member, Gesso, did an amazing job of welding it up and it works perfectly. In fact the surface rust and welds seem make the Smog techs at the local shops think it must be stock and never give me grief.
I'm selling this together with a 1.6L Flyin Miata high flow catalytic converter that Gesso modified it to fit up properly to the 2.5" DP flange and spacing so it will link up to any catback exhaust. This one was CARB legal from FM before the law changed on high flow cats in CA so I'm assuming it still is.

Yes, you are right! If you had a 1.8L with the same turbo then this would bolt right up. With this down pipe and cat the output of the cat would line up with any Cat-back exhaust.

IE, need a custom 1.8L manifold that mounts the turbo is the same place as the 1.6L Greddy.

Seems that a lot of people want to buy these parts separately:
$175 for the down pipe
$50 for the FM high flow cat (note: you may have to have an exhaust shop weld a smaller flange on the input side depending on your setup)
