I am going to install cat-back exhaust tomorrow. Can I re-use the OEM bolts? If not, will a 1/2 inch bolt fit into the cat- holes? I have a hard time finding SS bolts in metric size but avail in 1/2".
Thanks for the help.

 

yes they are fine to re use. Just make sure you use a copper paste on the threads to make sure they seal and wont come loose.

 

You should be fine...

My Quebec's winters rusted bolts were still fine after 5 years when I got an aftermarket catback exhaust a few months ago.

Just make sure you get the gaskets replaced... New ones should be included with your new exhaust system.

Enjoy your new exhaust!

 

when I reuse any bolts i just check to make sure the threads look good and that the bolt head isnt damaged. I always (especially on exhaust) use never seize.

 

theyre reusable unless theyre like mine and impossible to get off in one piece...wow that was a pain, and they didnt survive.

 

mine sliped out just fine. its subjective however. If you use your man powers like snypr its gonna need new bolts.

 

That was my case, it does not come off and before damaging it, the guy in the shop just gave me new ones with locking washers & gasket for free.
