You can check your local exhaust store, they might have one for SUPER DIRT CHEAP.

 

Have you changed the mid-pipe? If not why would you need this gasket. It can be reused unless it's damaged.

 

Yeah, the gasket that goes between the exhuast manifold and midpipe should be the same size as OEM; I reused mine

 

Mazda and there "Butter Bolts". I'm a heavy equipment mechanic. I deal with 700ftlbs of torque on bolts all the time. And I have never put a wrench on a tiny little nut and just turned it and it rounded off. So these had to be cut off.
Thanks Mazda.

 

I have the borla exhaust and a mazda tech reported that I had an exhaust leak at the catback.. will this fix my problem as well? Stock cat btw if that matters.
