Pretty lame video, but I thought I would put up something since the pipes are on now. This is not a cold start.
Very nice rumble at idle. Just slightly deeper, but more aggressive and louder. I wondered about the smell, but really don't think it's strong or bad. It's mid 30s and raining, so I can't really see what she sounds like or get a good butt dyno. Initial impression is she sounds more open, throaty and feels more responsive. Noticeable sound increase in the cabin. No rattle, high pitch, vibration sounding tin can issues. Just deeper, louder and smooth.
