The Aeroturbine will eliminate that drone. I'm not sure though who makes a system with a 3.5" DP. Someone posted one here not too long ago. It might be tedious, but try running a search on the site for the 3.5" DP.

I think losing low end torque because of a big downpipe is a myth. The turbo already gives a lot of backpressure.
Might be something wrong with the programming of your truck. Mine is torque from idle on up.

There was a memeber here several weeks ago that was switching back and forth to see which DP he liked better, 3.5" or 4" DP. He had a mildly modified truck, and ended up settling on the 3.5" DP. Had more torque and better driveability, if I remember correctly. I'll try to find the thread and post a link.
