Keep up the good work MrRyan. The throaty growl of your muffler MOD is right-on. The exhaust note you have achieved with such a simple change is better than the majority I have heard (from newly purchased $600 to $800 dollar systems to other homebrews). Consider covering the holes with mesh to keep debris out. Also you may want to consider tack welding a small cup shape (with outlet facing rearward) to cover your new screened opening (covers and protects the opening, but still allows your growl to escape.


S.T.E.M is a wonderful thing.
