Ok, built a nice system for my full size Chevy van, 6.2 N/A diesel. I used Hummer headers, 2.5 inch mandrel bent Y-pipe and 3 inch mandrel to the back. I was using a Super40 as thats what I had kicking around, it droned alot at 100-120 but the Fluid damper shut it down alot more. I bought a Hooker Aerochamber figuring it would be very quiet, I have heard them before and they were, WRONG. Its so f*cking lound at 100-120 I can't hear myself think and it braps something fierce, sounds like crap at certain throttle angles.
What can I use, add a resonator, add a cherry bomb? Magnaflow and resonator, please help???????
