Loved mine. Great sound and good performance. Mine were one of the first out the door from V&H. Got lots of compliments and lots of yucks. Sort of a love it or hate thing. My bike was lowered 2 in and the only time I ever had an issue was a hard right turn going up a driveway curb. Tiny little nick.
As I mentioned in another thread, unless you're seriously lowered, no way to hit that pipe just turning hard. There are a lot of Harley guys that hate 2-1 pipes. I love mine. The sound and power are awesome.
My NT is lowered and I ride... I have dragged the tip of the pipe enough times that it's scrapped up.
I think other people ride like ladies or don't know how to corner
