Well here soon I'm getting BBK 1 5/8in. longtubes to put on my car. I have afr 165's and was wondering what is the best method to match the gaskets. Fel-1415 is what I would use.
Should I match the gasket to the header opening or to the exhaust port opening on the AFR's? What would be best and why?
Thanks!
