Had a little free time today so I thought I'd give it a try. Definetly improved standing start response. Also seemed smoother and actually quieter during normal acceleration with a little more exhaust noticeable. Sounds sweet under WOT. By the way, for a relatively quick way to shape the PVC tube, turn a belt sander upside down with a 60 grit belt in it. Worked pretty good and I finished it off with a 120 grit belt.

 

glad it worked out for you
