i had straight pipes on my LS1 camaro, no exhaust whatsoever, so i kinda know what loud is (and im sure the box wont be louder than that, no way), and that is music to my ear, and my GF loves the sound of engine compared to some music on radio (we barely ever listen to radio while driving so its kool).
i think that the way i can control this is by the size(diameter) of the pipe used / the size of the hole, but of course u can never go back if u make a bigger hole and want to go smaller.
the work will be done by me and my friend, so all the $ aspect of it will be bending the pipe and cost of actual pipe, so im thinking $50 range or so, wouldnt you say?
i gotta actually get ahold of my friends dad, he has his own pipe company, so i may just get this mod virtually free
i hope hehehe
