Help! Anyone know Borla X-pipe bolt size?
Acquired used Borla x-pipe 60547 without front flange bolts. Anyone happen to know size and length required?

The factory bolts are studs that thread into the x-pipe flange. The Borla x-pipe is not threaded to receive the factory studs which are 10MM. The Borla instructions say to use the bolts provided. None were provided . If they were, they would have to be 8mm to pass thru the Borla flange holes. This seems way to weak. I am trying to drill Borla's flange holes larger to allow use of 10mm bolts. The flanges are work hardened from welding. I've used up 5 drill bits so far and I off to try to find solid carbide bits ( on Saturday?). Good luck to me. By the way, the bolt length required is 3 inches.
Correction: 3" too long. Could not tighten. Ran in threads and had to add washers. 2.5" will work better.
