5 of 5 A No Restriction pipe! Don’t cut this pipe up. February 14, 2016
taco eater : Ninja from New York, NY  
In one of the Simonini Circuit pages (I think it’s the chrome pipe) someone made a comment about “closely dark secrets lie within”. Don’t believe the hype! This pipe is a straight through circuit pipe. I was convinced that the rectangular baffle was a restrictor point like some pipes. It’s not! I did some investigating and was going to do major surgery on the baffle, drill out the rivets and cut any/all of the restricting out. There isn’t one. The baffle is a straight through glorified glasspack. So leave this pipe alone no need to do any reconstructive surgery on this one. Mount and blast to the moon.
