I need some help

I personally am not familliar with the sound, but I am having a hard time believing that it could possibly be louder than my old school glasspaks that I still choose to run (much to my neighborhoods dismay :D ). I find generally that any system is only really loud at hard acceleration or WOT, but not when cruising, so I am not sure why the highway would be any more of a problem for you than it is for me, which is little. :shrug:
 
HAHA.. Just drove in my friends 93 cobra.. yeah not going to go with one chambers My ears are still ringin...Pretty much same motor as whats going in my 66 but has brodix heads and a procharger.. I am seriously deaf....

Dont think my neighbors would like it when I leave for work at 12 am
 
I would also like to add that on a stock engine, they are nice: the more power a given engine makes, the louder it will be using the same exhaust. My 67 with glasspacks isn't noticeable at all at idle or mild throttle but has a nice growl when you get on it. It is completely stock, (until spring!). After my mods, I might reconsider those things.
