Trying to figure out which flange to order to bolt up to an Apexi b-pipe from the cat on a 2000 civic. Looking at the vibrant website, it seems that the bolt circle on the 2.5" is a little large and the 2.25" is a little small. Just want to make sure I get the right one on the first try. Bolt centers are 2 7/8".

Anyone have any experience, or know what size flange I should be ordering? Common sense tells me to get the 2.25" since the pipe matches, but it doesn't really matter if it won't bolt up. The exhaust shop told me it's metric and that I need to find my own flange. I don't remember having this problem last time I did this...

 

The shop didn't have one? Pics?

 

No. They told me to bring my own lol. It's the standard size flange, I'm just tying to bolt up to an Apexi ws2. I think I'm just going to buy one of the telescoping test pipes off of eBay, cut the rear section to length, and weld it on myself. It'll end up being cheaper than sourcing a flange and paying the exhaust shop for 6" of tubing and it will be all stainless that way.

 

Problem solved. Vibrant 1482 2.5" is dead on. Figured I'd post the solution for posterity, since no one seemed to know anywhere (including Vibrant, who didn't see it necessary to return my emails)
