Tried searching but couldnt find anything on the site.. Went to Autozone and kragen and even the dealer and no body knows what size the nut is. If I had one to compare I would and I dont feel like stuffing my exhaust in the car to take it to an autoparts store.

Any help would be appreciated.

Thanks!

 

Note entirely sure what ones you're referring to down there, find most of the studs are 10x1.5 in the exhaust area. Know the standard inconel ones are expensive, good reasons to use them though.

 

The ones that go to the studs in the cat are M12x1.50, which is a slightly weird thread pitch.

The nuts that go on the studs connecting the downpipe to the turbo manifold are M10x1.5.

If you need parts just give Ray Crowe a call at Malloy Mazda, he knows his stuff. I sent in a general description of about $900 worth of stuff I needed and I had an itemized (and nicely priced compared to the normal price) detailed list the next day. He really is the go-to guy on OEM parts
