Overthinking is what I'm good at doing. So... I'm currently going down the rabbit hole of exhaust bolt material. 2008 Tacoma. OEM manifolds w/ cats near the end flange. I believe the oem manifolds are stainless. The flange has a nut permanently affixed to the backside of the flange. Already had to drill out one of the bolts, so that'll receive a totally new nut and bolt. The other 3 are simply getting new bolts since the threads were fine. They're just rusty and 16 years old.
New mid-pipe (y-pipe, whatever you want to call it) is being installed. 304 Stainless.
Obvious exposure to road grime. Not driven heavily in winter, but chance of some salt can never be ruled out.
316 bolts w/ nickel anti-seize my best choice here? And the one that is a full replacement, a 316, but use copper washer on backside?
I'm also not opposed to spending on titanium since it's only 4 bolts if that would be a much better choice when considering corrosion resistance, etc.
What do the experts say here? Any of the above or have a better idea for me?
Thanks!
