I've got an '01 Z71 with race bullets on there now, but its just not the sound I want. Dumped before the axle. Its louder than stock thats for sure, but I want more rumble. I had flows on my old Mustang and they sounded gooooooood. Wish I could get that sound back..impossible I know, but I can wish. I'm thinking of going with 1 chamber flows or 2 chamber original flows. Which offset would I need? true duals unless a dual I/O 40 series would be louder than 2 40 series.


help me out..i'm not too up on this. Thanks!
