How do you determine the different curtis sparks pipes? I heard they made a MX and TT. I was told when i bought it that it was a curtis sparks pipe but no identifying marks. Are they good pipes or yesterdays news?
Most of them will have a nameplate that says sparks racing and it will be stamped with TT or mx. They are very good pipes. I saw one on ebay awhile back that was supposed to be a Big Bore mx, but it had no nameplate. I'm not sure if that was standard for those pipes or not.
