    that cat back isnt going to help emmissions really.. i'm sure you've installed the o2 simulators .. so just put on any catback, (i used a flowmaster) but a lot of people use loudmouth... might be too loud though.. then have someone weld it together and your good

    Get some high flow cats put in and then you will pass just fine

    The catback itself wont make you pass an emissions test if they put a sniffer to your car.

    What kind of pipes do you have that come off your headers? Do you have an off-road y-pipe? The high flow cats would be installed into your y-pipe area right after the long tubes. They aren't real cheap either btw.

    theres some really cheap high flow cats on ebay for like 60 bucks each.. but i dont know anything about them.. they may have problems.. i think (correct me if i'm wrong) most decent high flow cats go for about 140-150 each.. and the installation is gonna be like $150-$200.. but guys have gotten better deals then i have.... If i were you, I'd get your o2 sensor deleted (or o2 simulators) and run one cat at the foot of the y pipe

    I don't know about labor for install though, that would vary by shop. Random tech makes real good high flow cats as well.

    XXXXXXX sells their high flow cats for $70 a piece. How good are they, well I have installed them on a ton of cars and never had a problem with one of them yet. Dyno tests have shown around 3 to 5 horse loss. I had them on my Camaro and they are nice. Made of "409" Stainless and their really small to fit in tight spaces.

    No, they don't have to be welded on. You can use a c-clamp or band-clamp.

    I had a single hi-flow cat installed after the off-road y-pipe. A custom muffler shop supplied the cat and it cost me about $160.

    90% of exhaust system need to be customized. They are not just straight bolt-ons. Alot of times they fit great on 1 car and shitty on another. Alot of times, bent steel (especially stainless) wants to go back to its original shape. This cause difference which need to be modified.

    You are gonna have to hack that pipe up. Even if you buy a catted Y-pipe it may not fit perfect.
