Best cat-less downpipe?

Hey guys! My cat recently got all messed up. I need to either replace it or remove it, so I've decided to look for a cat-less downpipe to replace my current dp.

If anyone could give me a few pointers on what I should buy, I would really appreciate it! Also, would I need to do any PCM reprogramming with just a CAI and Downpipe replacement?

Sorry for the amateur questions, but hopefully someone can help me out.

Thanks!
 


ZZP sells pretty nice units. hogan performance is also an option.

you will need a PCM to delete/turn off the SES light that will be set from having no cat on the car.
 
Well I've had my "check-engine" light on every since my cat messed up, so I'm kind of used to it now lol
 


[FONT=Tahoma, Calibri, Verdana, Geneva, sans-serif]Headers are nice, but wouldn't I need to get a reprogrammed PCM with headers to get the full performance from them? Or does that become more important when doing things like smaller pulley?

I figured a downpipe would be an easier, less-hassle way to fix my cat problem. Since I wanted to get rid of it anyway.[/FONT]
 


there is a place downtown here that will ceramic coat whatever, would I get any gains from ceramic coating the downpipe?
