Well my 1/2" drilling job didn't do that, I think I need to get craftsman tools for a better job next time. Wow that is huge man lol. Im gonna keep my stock exhaust with the small 1/2" drill in there just in case the epa goes crazy or something, you never know. Until that time Muzzy will be on mine.

That is why it is important to do a controlled test, record the reference (stock), then the modified, everything done the same between the recordings as much as possible - same microphone, microphone in the same position and distance away, even do the same duration and same variety of RPM settings - like a script. Only then can you use the recording as a comparison. A single recording without a comparison for reference is not very useful other than getting the overall character of the sound. While that's nice, it doesn't tell a lot about the loudness. We all know what our bikes sound like, of course, but a recording is a totally different experience - you really need a before and after recording to allow a third party to make a comparison between the two.

That is a pretty interesting sound coming from your pipe. I kinda like it.

I hope Gravy Train comes through with the before and after with the Muzzy setup. I'm very much looking forward to hearing the difference.

Not at all! What you posted was very good, it was an excellent recording - thanks for sharing that. Like I said, it does sound pretty cool.
