| Ask Wally about running 8" stacks with a muffler under the bed to tone down the drown. Wally will probably have the answer.

| I don't have stacks, but I will say I know a couple people who do. And I can tell you they hate the noise. Plus there were a couple occasions where they needed that extra bed space....and didn't have it.
