Kevin, your pipes sound great and the workmanship looks exceptional. But please do me a favor and never do a burnout in a crowded parking lot with a kid on someone's lap ever again. It doesn't take much (a drip of
oil) to make a fun moment a horrific one. I would recommend you pull down that one and replace it with something else that better markets your craftsmanship.
Good luck with selling these...I'm sure there is a market for the right price.
