Re: Removing catalytic converter?

make it louder, probably a little more raspy
SES will still be on you will have to get a Simulator, get a mail-order tune, or tune it yourself.
Power? we've already talked about what it will do for the power and talked about everything else already

much raspier(if thats a word) up top


EDIT:96greenmachine, i have !cat and flowmaster 40, down low it sounds mean and aggressive but like mentioned right above, it is a lil bit more raspier up in the higher rpms, improvements-powerwise:i felt it up at higher rpms

Re: Removing catalytic converter?

I meant 13, but to awnser your question, no he couldn't drive it. He stalled that thing constantly in front of my house. His car wasn't stock, I remember he had shorty headers, a pulley, K&N filter, and he had cutout a plastic piece where the filter sat to suck air from bottom, and he got rid of factory tubing from filter to throttle body and put in a smooth connector. He shoulda had a 12 second car probably, he even said he couldn't get off the line fast enough.
