Default What combination of downpipe and midpipe for prodrive axleback?

I'm searching for a catless bellmouth downpipe and would like to keep what I have now but I dont know what mid I could get. From what I've seen I'd need to cut something in.

I have the COBB catted and stock mid pipe. It's bell mouth, but it's catted so not sure if that's something you're into. Any particular reason you're going catless?

Here is the thing, the prodrive axleback is the same length and fitment as the stock axleback, and 2.5 inch diameter.....so you will need to find a setup that fits stock, ending at the axleback.

one option is the turboxs catless stealthback. that will bolt up good, I have this setup with the prodrive and its great.

another option is to use (most) downpipes, and hook it up to a prodrive or maddad mid pipe, to hook it up to the oem length axleback.

Cosworth USA is clearing some old Prodrive stock on ebay.
I've seen a Prodrive downpipe for an amazing price there.

Prodrive has catted and catless, with catted flowing as well or better.

Then alll you need is Prodrive center pipe that is cat-delete and resolves the rear oxygen sensor as well and you've got a Prodrive system, like me. I've got the prodrive uppipe as well.

Going with catless simply for added power, and nothing to go wrong (element failing down the road)

Seen one maddad midpipe, looks like a rare piece...

That looked great until I noticed it appears to be part of a two-piece downpipe and I while I dont mind mixing and matching It'd be a pain to mate the other downpipe piece and midpipe plus I dont think I want 2.5 all the way.

Take a look at this, this is an Sti Prodrive downpipe. It's a shorty downpipe, similar with stocker.

I bought my downpipe from ebay.co.uk.
