I was thinking I may have to do that. I know a place up here that does water
cutting that may be able to cut it for me.
May not be much more to cut a few of them.......Will look them up in the
next couple weeks.

I've seen that on several of the aftermarket headers and wondered what it
was for......

I am finally getting around to making my custom headers. So not a repair
job.
Couple of design features in the currently available header that I don't
like which could/should be easily resolved.
The biggest one being the collector. (merge collector would not be expensive
to add at the manufacturing stage.....)
Working on a 4-2-1 design, possibly with the ability to bolt or strap to the
original point by the motor mount to help
prevent cracking etc.
Thanks for the note!
