Straight piped my Mack.

Well this weekend I straight piped my Mack.
Its a 2000 CL 713 with a E7 460hp engine. Well it sounds sweeeeeet while under throttle but thats it, this is the first rig I have had that is plane just obnoxious while using the jakebrake while straight piped. It dose sound good while in the 1600 to 1000 rpm range any thing past 1600 is just crazy loud. Its so bad I have to find something to quiet it down or put some type of muffler back on it, if not I'm going to rattle my truck apart.
Any one out there ever have this problem with a Mack? and what did you put on to quiet it down a bit.
Thanks.

MIKE
