Maybe fit a pvc pipe plug in one of them. Also there was some thing called hisholm resinators in a post a long time ago. That looked like a much better way to fix droning. You mount these in a L shaped 90 degree dogleg off the main exhaust pipe, I think in the rear section of exhaust system. They change the tuned length of the pipe so that you don't get droning in that place in rpm band. It moves place where it drones to some place in rpm band you'll never see. Hope this helps Tim

No need to throw a lot of money at this issue. A lot of those charts you see are produced to sell exhaust systems not cure drone. GM had already cured drone you just reintroduced it with those B&B mufflers.
