A straight piped D-Max will do this because of the VVT Turbo... Its normal, enjoy the sound

i had the same problem when i cut the muffler out of my 4" system...drove around with it for a couple days like that...i know what you mean...its crazy loud if the pipe ends early (like... need ear plugs loud) once i got my straight pipe back in over the axle it sounded muchhh better......far less scream (maybe just because the sound was being routed elsewhere).....i think i may still get the diamond eye downpipe though....just to see if it will help my performance or temps at all.
