Hi everyone,
I found a similar thread post about someone looking for a down pipe gasket, with no definite answer on what will work well. I would prefer a mazda OEM gasket but really don't want to spend $100.

Just purchased a FEED down pipe, and found this gasket but what do you all recommend. I definitely don't want any exhaust leaks in the near future

The gasket I'm looking at:
Nippon Reinz Exhaust Manifold Gasket in Canada - Canada W0133-1757914 Nippon Reinz Exhaust Manifold Gasket Canada

It's been a while – researched some other options I just don't remember what they were now. But I ended up staying with OEM. I did NOT want to mess with the down pipe a second time. Not only is it a PITA to access on the car, but just more opportunity for a stud to twist and break. If that happens the extra paid wouldn't seem all that bad. That was MY logic anyway.

Is there any options (links) that are not going to run me $100+ for an oem gasket? If oem is the only option what retailer should I go though.
The Nippon Rienz looks good but it has an extra hole in the gasket which can't be better for sealing/exhaust leaks.

Other option is i could get the NR gasket and use gasket cement to fill the hole?

I bought all new hardware for a downpipe install. You don't need to buy everything I listed below but maybe it'll help you out.

Just remember that both gas pressure and temperature are significantly higher with this car than most.

Just ordered the OEM one, better safe than sorry!

Don't mean to offend if you already intended to, but be sure to chase the stud threads as best you can and use hi-temp anti-seize. FSM page F-113 says torque to 47-68 ft/lbs.

I purchased all of the recommended hardware, as quoted by SonicFD

OK, but you should still chase the manifold (female) thread and use that copper anti-seize.

what do you mean by "chase", kind of a newbie lol

Sgtblue

No worries. If you have a tap and die set you would use a tap to "chase" or clean the threads. Doing so ensures that you get proper torque. And maybe more importantly with anti seize and clean threads you reduce the risk of breaking the studs when tightening things down. Trust me you really don't want to do that.

ok, ill be sure to do that, i have a mechanic friend that i can borrow a set off so it should not be a problem. Ill make sure im using the correct size tap, dont want to mess it up! Just a DIY guy myself, but learning more every day! Thanks Sgtblue
