Looks good Chris. I like it both ways, (now don't get the wrong idea) old school flapper is always a hit. I have one on my little 1110 with a Briggs, and at idle it's cool
Just flops up and down, but it is one loud moe foe.
I've got the stack on my 100 running off the muffler which is much easier on the ears, and I just cut it at 45 and it looked as sweet. Actually it's a little more than a 45, looked slicker.
