99 Cali Emissions guys, parts help needed
So I have everything I need to do the entire exhaust past the exhaust manifolds back.
Since it's Winter and refuse to do this on my back on jack stands, I'll have a local guy I trust, swap everything out. I want to supply everything necessary to avoid bend me over markups.
So the front manifold hand off to the pre-cat has 5 holes for studs and/or bolts. From the OEM diagram, they list only two studs (14070-53Y00) and two nuts (20602-41G00), but no bolts or sizes. They might also be brass. Anybody know either the sizes or Nissan part numbers? Same with the rear manifold to "Y-Pipe" gasket/seal. Different searches always bring me back to the same information short sources.
As for the rest of the nuts, bolts and lock washers, all stainless, as all the parts are stainless as well. Hopefully done for a VERY long time.
Any guidance would be greatly appreciated!
Thanks in advance!

Cant really help with any of that sadly, infact i never could get the manifold and precat sections separated as the studs/bolts tend to be horribly rusted where they snap instantly to even the smallest amount of torque. Im curious though, why replace these? Even if the precats are getting clogged, you could just bore them out and slap them back on with no issues, you probably wouldnt even get o2 codes. Even if you did there are extremely cheap and easy ways to remedy that (ie; defoulers)
If you cant find the proper gaskets though, you may wish to consider something like this:
basically its a graphite based sheet of gasket material, you cut it to shape and slap it on. I never used the universal sheet like shown in the link, but the gaskets for my headers are made of the exact same material and they are great, they have some crush to them so even if your surfaces are not perfect they will form to create a proper seal. Just gotta be careful not to drop/bend the gasket because the material is kinda brittle and can crumble easily, not something thats an issue once its installed though.

Ha! You also live on LI. You know what our State Gvt did to our CARB compliant laws. And anybody installing can be fined $10K to start for tampering with any part of not conforming to CARB compliant rules and parts. Inspection is due by the end of the month. Gotta get this done..... FINALLY!

edit; whats stopping you from passing inspection? What codes? If its o2 codes, just save your money and use defoulers. Again, they wont stop you from passing inspection, shops dont care let alone bother to look lol. Save your money!!!!

99 Cali Emissions car with 4 O2 sensors
unless they changed the law in the past year, you can ignore it. None of my cars have ever been compliant and never have i worried about it being an issue. Its a law thats extremely difficult to enforce, basically unless your car is impounded or being inspected by the DMV, it will never come up. A normal shop wont care about this crap. Ive had headers and an aftermarket, non carb compliant cat on all of my cars, as well as extremely blatant nonfoulers - never once did anyone bat an eye. If youre doing all this exhaust work to comply with this dumb law youre pretty much wasting your time and money. At least thats my opinion. No one is gonna go under your car looking for serial numbers on your cats lol

Whats the issue that is preventing it from passing inspection though? Codes? Exhaust leaks? Still not understanding why youre replacing the exhaust in the first place lol. My first max was a cali spec 99', i had headers which replaced/deleted the precats +ypipe, as well as non foulers to prevent any o2 codes. The main cat was a magnaflow i think, whatever warpspeed was selling as a "fast cat" at the time - that cat was also specifically illegal to use in cali and NY but that didnt stop me lol. Basically everything was noncompliant, yet i never had an issue ever involving the carb law.

Now I have everything new and it's getting done as soon as I get the last few little things.

Hey Jack ****,
Thanks for looking and finding that diagram. Been there, done that.
See that bolt pointing upward in the front pre-cat (Sec208) at the bottom? Nowhere is that bolt given a size or part number. I think I need 3.

I was bored last night, i found the part number but unfortunately its discontinued, no size listed either. You do need 5 of the bolts though. I think your best bet is to take the cat/manifold into home depot or wherever and try different bolts until one fits.

I wish! The manifolds have the threaded side of the equation and I'm not messing with them! LOL I got enough problems!

Are you talking about Part # 20802AA? It shows it on the other diagram I posted.
