Exhaust Question - Custom exhaust soon. What flanges needed to bolt to cat?

[DSMRevolution]

I am posting this in General (not noobie) forum because its a pretty simple question. Anyways, I ordered this muffler from Ebay:

Apexi N1 Muffler
If that link doesn't work, let me know.

I am having the exhaust shop build me a 2.5" press bent catback exhaust and I need to know what flanges I need to order. I am not having them build me a downpipe because I am ordering one that is pre-made. I want to get a flange that will bolt up to the stock converter to the catback that the exhaust shop is making me. I also need this flange to bolt up to a 2.5" aftermarket downpipe (extended downpipe to replace cat).

So basically when I get my stock downpipe out and install my aftermarket downpipe, I want it to be a bolt up simple installation.

RRE has some exhaust flanges that should work, but I am unsure of which one I will need. Any help would be greatly appreciated.


Oh, and the reason that I chose to get the Ebay special is because both mufflers will sound and act the same (except one will say Apexi on it) since they are both straight through design.

Thanks again

Just wondering why you're going with press-bent over mandrel? Or are you saving your money for when you upgrade to a 3" exhaust?

The shop here that I like to take my car to doesn't have a mandrel bending machine. That is, unless they got one since my last visit. I would perfer mandrel bends, but there really are not that many bends as it is. If they can do them now though, then that is what I will get. Thanks

I actually wanted to order these parts tonight so I could get the work done end of this week. So if anybody knows, please let me know ASAP! Thanks
