Don't do it, it's not worth it.
the decibel level really depends on what exhaust you have. taking the cats off will merely emphasize the exhaust you have now. as far as the law, the only trouble you would see is if you had to pass smog, but in ohio you don't. i dont think you will see in mpg. you probably know already but you will need mil eliminators.
the biggest difference i noticed was the raw smell of spent gasoline. but that is a plus to me.

I dont know how different it is from each state but I pass inspection every year. Noone gets mad at me down here, in fact everytime I drive into town i get a compliment on my exhaust. Cops never bothered me either.
Exhaust:
SLP O/R X
SLP LM1's
i pass every year, but people hate me because I have L/T with SLP. The best sound!!!! I love it.
not to mention that you would be violating federal law.....
After longtube install, i went with an O/R X-Pipe. My exhaust stinks to holy hell. Cats are going back on.
cats are gay
It all depend on the state as far as the smog check. In my lightning I had no cats and passed emissions because they just plug into your OBD and if your car is tuned right it wont throw any codes and you will pass. If it does throw a code the machine will tell the tech to hook up a sniffer and then you might fail. I never had any issues with cops, people, inspections, or emissions. You could smell the fumes in the garage but the machine passed it so it passed. Also I was 486rwhp before the delete and 510 after the delete and tune. I say do it
Dude, you have a 2003 Mustang GT that is probably pretty damn close to stock. Why do you need to run no cats>???
That kind of stuff makes me laugh, you should do an A/C delete next, then you will have a race car!

ooooo, i change my vote then. i didnt look at the vehicle
some of you guys mention the raw gas smell..... I had an off-road X-pipe on my 87 LX and the inside of the car smelled AWFUL. Had an off-road H-pipe on my 06 GT & now have an off-road mid pipe on my Lightning, and both vehicles never had any kind of exhaust smell inside the cabin. Now that I think about it, the 06 GT & L have good tunes, and the 5.0 wasn't dyno tuned. Maybe that's the key with the smell?
Go and cut your cats and sound like every other mustang
OR ProChamber here,love it.You`ll have to turn the rear o2`s off or your throw a code!
I've never had any issues.
