they make different lengths of cherry bombs. shorter ones are louder longer ones are quiter. remember there are cherry bombs with jus holes in the inner pipe and some with baffles, the with baffles you can turn either way for louder or quiter. and after a few months if its to quiet for ya run it up to speed get it really realy hot the douse it with a puddle or hose youll destroy the glass inside it and itll get louder.
Getting into some technical stuff with a free flow muffler like this you will lose a lil torgue from loss of back pressure but the hugher revs will pick up a lil power. yes it will be louder but as stated you can tailor the noise with lenght and baffling
another thing you can do is install a turn down. i know in washington state legal loudness is 95 db on the a weighteed scale measured at 10 feet pointing to the tip. 95 is legal 96 is illegal. a turn down redirects the sound energy downwards instead out outwards. pay attention to all the nice new cars with turned down tips like the turbo volkwagens, the old dodge turbos mercedes, bmw's
above all remember its a jeep its your jeep so what you want to it and if you dont like it sell the parts on here and try again im sure someone would buy a slightly used cherry bomb for 10 bucks
