at www.jegs.com part number 389-17233 says that it is duel outlet and i was wondering what the mid pipe is a 3" and was wondering how loud this is?? its going on the back of a 330 hp 350 its not extream but will it let it breath enough? and i dont know if i really want something SO loud and was wondering how loud are they really? american thunder=40series? i am eihter goning to get the random tech or the flows

 

if ur making 330 HP then i would not recomend an 80 series flowmaster. the design of it would be to restrictive. get a muffler without power robbing "sound chambers". however i can't tell if that comes with the 40 or 80 series, while the 40 series is better then, any straight through muffler will still outperform, and as far as sound goes, i don't think that its that loud, when u first put it on u will be impressed or want to make it quieter, at least i did, but they're not really LOUD loud,
