    just talked to a guy that said they just look for cats. Most people are to lazy so they don't bother.

    would it be worth getting long tubes if I put the CATs back on? I just don't want any trouble.

    Big gains with stock cats, or with aftermarket i.e: Random cats?

    9t8z28, how do you pass with LT's in Pa? I live about 30-45 min. from Doylestown and maybe you could give me the name of the shop where you get yours inspected..?

    I was going to use the stock CATs. Is that bad?

    Should I still get a Y pipe or is that not a good idea if the CATs are going back on?

    What gains do you get from just long tubes. Is it at low or high power band?

    I just want to thank you guys for answering all of my questions.

    You will have to replace the Y if you get LT's, and your stock cats will not work either. Best bet is a pre-catted Y matched to your headers.

    I will probably get the Texas speed Pacesetter combo, but there are others to choose from

    I just looked at that on Texas Speed and it is $730.00. It isn't that clear on what you get either. Do you get the headers, Y pipe and the CATs? Also do any O2 extensions come with it?
    Once again, Thanks.

    Yes, Pacesetter (I believe Ceramic coated) headers and Tsp catted Y-pipe for like $730 You need to buy o2 extenders, I think they're $25 or somethin like that. Give em a call on Monday, I'm sure they'll lead you in the right direction.

    Nah, normally $390 for headers and $350 for TSP catted Y...save $10 bucks haha. But a lot of other catted Y's are in the $500 range!!!

    Hell, if it wasn't for having to buy new CATs this project wouldn't cost all the much. You are right, those other Ypipe CAT combos ore way more expensive.
    Well, I guess I can sell my old cats to that guy from this site.

    Think I'm gonna order my Corsa CAT back and install that one on my own. Then buy the header Ypipe combo later on and pay some one to install it for me. I know a guy that will do it for around $300.
    Will I need a tune after all of this or will I be OK?

    No dyno tune but you'll at least need a mail order tune to delete rear 02's and emissions so that it doesn't kick codes. Or go with o2 sims, but either way it'll kick codes as soon as you remove the stock exhaust.
