Default What to use to keep exhaust bolts tight?
What do you all use to keep your bolts from loosening? Im sick of having to tighten my exhaust all the time. What is best?

What bolts are you using, what headers are you using, and what tightening method are you using?

I use a standard 1" ARP stainless 5/16" 12-point bolt and have never had any header leaks.

Split locks have served me pretty well, so has safety wire.

Not for the headers for the exhaust joints. They are stainless slip joint clamps

A band clamp or u-bolt clamp? Neither should be comming loose all the time.. or are you tightening them like a 12 y/o girl?

Drill small holes in each fastener head (nut and bolt head) and use some safety wire.

Wierd I've never had those come loose before. If you think you've got them tight enough and they still keep comming loose, use some stover nuts and that should do the trick.
