What are folks using for the downpipe to exhaust hardware? My last attempt using some stainless metric hardware failed miserably when one of the two decided to gall and bind the nut to the bolt.

It seems like it's better to use a lower-carbon steel bolt, grade 8 (to stay away from chrome plating) with lots of copper anti-seize as a logical route but I figured I'd check with the gurus here.

 

Any ready go-to part numbers from ARP or a collected list for McMaster-Carr?

 

TIA,

Brandon

Consider a nickel based anti-seize rather than copper. (Much higher temp and won’t react with stainless as copper does)
