dodge ram 1500 needs louder exhaust

i have a 1997 dodge ram 1500 with a 5.2 l. I removed the cat and have straight pipes coming out of the manifolds meeting at a Y with a glass pack and i want to know how i can make this louder but still keep a deep growl.

on my 96 i cut the cat,run it back to about right behind the bed and split it into two pipes and run it put a glass pack on it pipe and then put 4 1/2 in chrome tips on it.and trust me it is very loud,and it still has a very deep tone

thank you. i also was wondering if anyone knows how to replace the vacuum hoses for the 4wheel drive?
