Hey fellas, need some experienced info here...

I got a Tanabe G Power Medallion recently and was trying to install it on my car tonight, well, after taking off the stock exhaust, I realized that I don't have the bolts I need.

My question is, are there any special bolts I'll need for the catback piping flange connections? Or can I just go to Home Depot and get some regular bolts that just fit?
