Taking off cats doesn't make it 'unbearable' persay...for a few people the smell may get to you...you can always just have your cats deleted with an edit prog...

No its really not...its your PCM thats saying that there is a restriction in flow...you can cheat your computer to think that there are no cats and itll run as if you had no cats...the existent restriction doesn't have anything to do with it...its all about your PCM...

my car had no cats, and it doesn't sound really loud. Even i had an electric cut out installed. the only thing is the smell, u could smell like the car is running rich. its kinda like a strong gasoline smell. Just my .02

With the 383 and longtubes, it will be very loud. It is even louder if you remove the sound insulation from under the carpet like I did.

Hope you have an extremely friendly inspection station.
