Cut Catylic Converter?
Ok , If i was to cut my Catylic Converters Off What positive Feedback will i get and what negative Feed back will i get
I hear that sometimes you can loose acceleration ? And then some tell me you gain acceleration ?
Ony this i would love to know is how does it sound with JBA Shorty headers - Flowmaster exhaust 40 serie's and NO CATS!!!!!!
Will i get more ROAR ,.. Throaty sound im close to that throughty sound i feel like my car sounded better without HEADERS!
More throatier ? What the solution i want more sound and i want more HP
Overall i want more HP !

its a very interesting sound lemme tell ya, i have the identical setup you have/talking about with the exception of the intake. if you would like i could send you a sound clip. its definately raspy 3-3800 rpm but doesnt sound bad otherwise.

I think you'd see some noticeable gains from replacing the cats with straight pipes, and then throwing in a single high-flow cat and maybe a $30 resonator near the center of the car to keep the *** sound away.
The nearer to the engine the exhaustrestriction is, the worse for performance -- Ford pretty much bolted the cats to the manifolds so they'd heat up faster, which is forlower emissions. It's just about the worst setup for performance, though.
