How Loud..?

Hey guys, how much louder do you think my exhaust will be once i make it "true dual"...instead of the current 2-1-2 stock setup. I got a 95 4.6L Thunderbird with cai and 3.27 gears.

Basically, i'm gonna cut the exhaust just after the tranny..this is after the 2 cats/o2 sensors so some back pressure will remain..and i wont have a check engine light come on.

How loud will this be, it's basically "open headers" with just a cat on each pipe.... My buddy said it should be LOUD, even louder then his 5.0 fox with mac header/full exhaust..

PS, the main thing here is to "open up" the stock piping alittle, cause right now i got 2 cats (which i'm gonna keep) going into a third cat and a resonater....coming out 1 pipe then splitting into 2 (2-1-2).. I am gonna leave the exhaust exiting under the car (midway)..

so you are going to take off the mufflers? that'll be loud. i wouldn't be too sure that the check engine light will stay off though, that little guy is a fickle bitch.

Hey man, well i already DON'T have mufflers...i'm gonna be removing the third cat, and a resonater....and cutting the exhaust before it goes 2-to-1...so it will open the exhaust to true dual, and i'll have only the 2 front cats on for emisions..along with the o2 sensors..

I already checked, the engine light wont come on.
