What kind of cat-back to use???

I've just installed a Borla header and R/T cat-pipe. Now I definitely need to do something with the rest of it because it now seems that the stock parts can't keep up with the flow on the new parts. What kind of cat-backs do you guys recommend and who has the best prices. I'm leaning torward a Greddy EVO, but I'm not sure yet. Also speaking of that will the Greddy Evo catbacks made for the earlier cars fit the new ones like my 04 RS. I read they will if you tweek the brackets a little, but I wanted to make sure.

what size is the greddy. i think i would go with a stromung mid pipe for sure, and then whatever axle back you want. personally, i wouldnt go with anything bigger than 2.25" as there would be too much torque lost at real low rpms. i have a stromung catback, but i think i will avoid the stromung muffler section when it comes time to replace it(my catback is mild steel).

stromung would be a good choice or the cobb, which is a stromung basically too.

Get a custom catback done for like $200. I'd go with Magnaflow myself, sounds great and flows almost straight through

Kostamojen, I like the way you think, thanks for the advice. BAN SUVS mentioned that too in one of the other threads. I've been toying with that idea. What kind of Magna flow muffler though ( I'm thinking your talking about a chambered muffler) and if I pull out the resonators and put in a 2.25 mid-pipe will it drone at highway speed? I just want it to flow and sound good.

I have the same set up as piker on a MY01 RS. Sounds like stock just a little bit more rumble and slight growl. With my ganzflow it can really scream at WOT. Custom Midpipe+WRX muffler installed was $220.

if youre looking for max flow a straight-through perforated core muffler is the only way to go. magnaflow has one with a 2.25 inlet and nice and small 3" rolled tip(part #14808 or 14809). i plan on getting that when my stromung muffler falls apart.

Thanks for all you advice guys. I decided to go with a custom mandrel cat-back with a Magnaflow muffler. I gonna try and post some pics when it gets done.
