I put my dirt track Beyea mufflers back on the car, just to see how loud it is with the new engine.
The phone.. does not do the sound ANY justice, at idle (900rpm ish) sound meter was reading about 90db. In person it sounds pissed, shakes your chest and rattles vehicles next to it. It's beautiful.
I wonder if I add a couple of 16" glasspacks in line with the beyea mufflers if that will soften the sound and keep the federales from bugging me....Might have to give it a try.
