stupid bolt question
So i had to remove the mufflers to replace the spark plugs. Since I live in Ohio I had to cult all the bolts to get the mufflers off. I replaced them with a variety of bolts from home depot including some grade 8 bolts. My place is to replace the bolts when I change the oil so I don't run into that again. So my question is what bolts do you guys use? Regular bolts? Stainless? Can I cut through grade 8 with a dremel if I need to?

When I installed my complete Fabspeed system, I replaced all of my exhaust hardware with stainless steel, including the header to block ones, using some marine grade anti-seize to isolate the stainless from the aluminum. I check them every oil change and no loosening has occurred over the course of 3 years. You can see many of them in this photo. I've pulled the Drivers's Side header about a year and a half ago to do the waterpump and thermostat, and everything came apart without any issues.

Mine were just replaced with overpriced Porsche bolts. I had my headers and cat replaced and the mechanic just ordered all the parts from the diagram.
With that said, I did my plugs and coils with another member on here and we put some anti seize on the bolts. Makes a lot of sense and I have it on my muffler clamps and some other bolts. I'll be applying some on the new bolts. It forms a nice coating on the bolt/nut and hopefully keeps water from reaching it and rusting it.

No idea.

The original bolts will just rust again like they did the first time - I say upgrade while you have the chance.

Haven't had to replace any bolts on my car yet, but when I do they will all be stainless steel (and good, high quality SS). It's always killed me to see what auto supply stores and dealers charge for bolts:

($5.25 per bolt...am I reading that right?)
Versus this equivalent bolt:

($0.43 per bolt)
And don't get me started on Home Depot. All that hardware is rubbish. Get stuff from McMaster - happy to help pick out parts if wanted.

Doing more research I read that stainless bolts don't tolerate the heat and stick together, brass nuts strip, and regular nuts rust. Seems kind of like an oil debate.

When I updated the exhaust system on my old 911, I used SS hardware and copper anti-seize. That was 10+ years ago and they are still easily removed. I got the SS nuts, bolts and washers from McMaster.
