ok so im getting my cat back today and i was wondering the bolt size on the flanges. i have just moved about an hr and a half from my old house and all my tools are there so i was hoping just to go to a place and grab the size(s) that i need. any other tools?

 

sorry I dont know the answer to your question... what catback did you get??

 

Metric or Standard?

 

10mm or 3/8"
