Downpipe Bolt Size?
 

I am preparing to install my DP, but as I read through the guides, most of them say to install SS bolts instead of reusing the factory studs. I was wondering if anyone knew the size of bolts I would need to buy? As I use a shop that rents bay space by the hour, and this is my only car, I can't drop the precat, and then take the stud to Home Depot or Lowes to get a replacement bolt.

I searched the forums, but none of the guides have the bolts on the list of tools or equipment. Some just say that their DPs came with supplied bolts. Thanks!

no one knows what size bolt they used?

Probably M10 x 1.5.

thanks man, at least I'll have something to try while working on this project..
