Maybe just put a resonator in the bottom of each one they are only about 18 inches long. We have a 95 freightliner with a 12.7 Detroit with one and it's fairly quiet. Also have a 98 9200 with an m11 with a single straight pipe, raised it up a couple of feet and that helped some too.should have asked if you have frame mounted or cab mount exhaust.
