Which catalytic converter to get?

[hotasianbuns]

I need to put a catalytic converter back on my 05 compg for emissions testing. I took my old one off when I had the SD headers put on. I'd imagine I need a 3" cat now...can anyone show me which cat they have used? Thanks!

Would this work? http://www.ebay.com/itm/Magnaflow-9...nverter-Oval-3-In-Out-w-O2-Port-/301381750797

if its just to pass emissions i would get a stock ish unit and some flanges and weld it up so that you can put it in just to test and remove and replace with a straight pipe after the testing. most hi flow cats arent very good if you have to get sniffed.

I got his one and had it welded into place when i installed my SD headers in August. Works. And just passed inspection here in NC.
Hi-flow is the way to go!

That's wht I'm using.. I have the cat codes disabled though and also don't have to worry about emissions here..
