I had read of someone reversing their Cherry Bomb glasspack, so the exhaust goes out opposite of the recommended flow on the cherry bomb. This was said to make a deeper tone, is this true?
Depends on how it's made. Some are louvered and some are perforated. The perforated ones flow the same either way. Louvered glasspacks will flow a bit better in reverse, but I'm not sure about the tone.
