Can anybody with a stock y pipe and stock b pipe be able to tell me what size the holes are for the bolts for the flanges that mate to the cat. I'm installing a test pipe but the whole size on the test pipe are half inch and I know this stock b pipe and y pipe are a tad smaller.

I just want to be able to buy new hardware before I cut the old stuff out

 

Your test pipe didn't come with new hardware?

 

I bought it used from a fellow org'er. No H/W came with.

Scroll down to post # 40 (last post on page 1). Maybe this will help.
