Right where the main cat joins to the 'y-pipe' there appears to be a mounting system that consists of a pair
of donuts, a 'y' shaped hanger, and frame brackets.

At some point they were removed and with the new exhaust system going in I would like to have them
back to support the weight of the heavier pipes.

Does anybody know the part numbers of the brackets that bolt to the frame (left and right) and the donuts
themselves? Pictures?

Thanks!

 

For the hangers, it looks like N326-40-640A. The rubber donut is N225-40-061. Sorry, no pics, but the parts diagrams can be found at Mazdaformance. What you're looking for is in section 2, the "Chassis" section.

 

The doughnuts can be found at most auto parts stores as well, for around $1.50

 

And that could very well be cheaper than what Mazda wants for them. I bought some washers I couldn't find at the local parts store, set me back over $1 per washer. I wanted to ask if he gave me the 24k gold ones instead of copper.

 

Thanks Jerry/Mark, I'll take a look at the parts diagram.

Normally I might try and make the bracket, but this project has dragged on for so long, I would just like to buy them and get it done

As for the donuts, I'll check the auto parts store...

Jerry is that nuber for the 'y' hanger or the brackets?

 

The number is for the brackets that bolt to the body. The 'y' hanger is part of the Y-pipe itself.

 

Thanks Jerry, I found that part, where are the bolts listed? ie: 9978-60-816

I looked but could not find where they are listed.

 

when i bought my car it came with a butchered exhaust system....after my 5 speed swap i realized that the gaskets and etc..were the butchered part..and it also has some of the 1.50 local auto parts hangers..they dont fit ..at all..if you stand beside my car you can see the crappy 1.50 rubber bands hanging down..so be careful what you try to fit..cuz the cheapies dont always work..

hope you have a better deal that in got!!

 

If that's the number that was next to the bolts, it's the part number. A lot of the generic stuff like bolts and washers isn't listed off to the side, just in the actual picture with the part number.
