They make the stingers too big on those things, 22mm OD. Probably 19mm is as big as you want to go, or 16mm ID. You can change the torque curve by slipping the stringer inside the convergent cone to the half way point.Picked up a second hand exhaust for 30$. Way too late and way to loud to give it a proper test, but just from the quick pull I did down the street, seemed to get a bit more bottom and mid response. Tomorrow I rejet and hopefully start looking at a cheap slip on muffler.

This is one I remanufactured to be useful.
