saw an 03 the other day in a parking lot, it sounded pretty good, looked underneaths and what do know, no muffler. looked like it had a pipe something like what genos has that replaced it. has anybody done this to theirs. he claimed more seat of the pants power and better fuel economy without excess noise in the cab. i know most you like it loud , but when your towing all day it can drone your head after a while. next, is it legal. can you get in inspected like this?i liked the sound of it from the outside, as long as it does not make it into the cab while driving. what the best way to go.
