Cut off the muffler put in the pipe. Stock quite in the cab. Somewhat loud outside.

My dad's got a couple cats he'd like to get rid of 
Now about not having the other kind of cat. I got my jeep the way it is and so did my dad. I put a mangaflow spun cat on my Christmas list this year and I want my dad to get one to end the trouble codes.
Any feedback on the magnaflow spun cats btw?

Had a quick question for anyone that has ever hard a Thrush muffler from Autozone, I'm in need of an exhaust bad and I'm going to be ordering just about everything from Mudfrog, but I listened to the way the magnaflows sounded and they sounded to quite period throughout the rev range. So I looked at a Thrush and I kind of like how it sounds, was wondering if anyone knew if it was annoying on the highway or anything or had any bad resonation problems?

Been looking at performance curve exhaust kits. I like the sound of the magnaflow but I am not sure what cat to get. I have an 2001 and want a 2.5" cat but it seems like there are a ton of options.
I was thinking this one: http://performance-curve.com/410250-...converter.aspx
but I saw this one recommended somewhere else: http://performance-curve.com/25thund...ter415250.aspx
Any help would be greatly appreciated.
