Looks like the DNJ seals on rock auto are a good choice as long as they are Viton. It doesnt say anywhere on the website that they are but it looks like they are. Does DNJ list the specs anywhere on these seals? If they are they the same as the OEM exaust selas then i'll be getting them. Thanks for the link above to Engine Builder good info for sure.

On another note has anybody used the below spring compressor
with success? I found one person saying it works but have not been able to confirm it with him yet. Looks pretty slick and is only $74
