I really want my mustang to sound deeper with its Borla Cat back. I really want to remove the cats, but then the whole emissions deal is a factor for me. If i remove the cats, would i definitly fail emissions, and what companys make a high flow cat that will make the car sound good?

Without cats you won't even be close to passing.</P>


Yes, there are companies that make high-flow cats, but I doubt that'll do anyhting for sound. If you want sound, get an off-road X or H-pipe (w/o cats) and come emissions, swap your factory H pipe w/ cats. After that, swap it back off. WALA!</P>

Yea you'll never pass without the cats. BUt the nice thing about he mustang is. If you install a off-road X-pipe. It will take you all of 20 minutes to put the stock H-pipe back on. It's deffently worth it.

If you have a car newer than a 94 or 10 years old then to pass emissions your computer will tell the story. They dont hook up smog suckers to your pipe if it is newer. So if you throw on MIL's, your computer wont know that you are running bad emissions so the OBDII reader at the emissions place wont know either. (Unless they look which is not likely)

Check the Conneticut state emission regs! In Pennsylvania they just rolled this out county by county and once a year you have to pass a computerized tail pipe and visualanalysis that checks everthing and you cant pass without your cats. Thats only in cars 1996 and newer. I heard that if you declare you drive your car less than 5k miles a year you are exempt however, so you could lie for 1 year but when they check the mileage the next you would have to pass if you drove more. This is hearsay from a garage mechanic so I am not positive its true in Pa.</P>


For what its worth.</P>

the more you second guess the long ish takes like blkstang said just do it and worry about it later, keep your old h and if you just so happen to fail you have couple of days to fix it so swtich them up and go back!
