Here ya go... Engine is full of S&S parts, 106". Best sounding and performing pipe out there. I like the look but can understand why others may not, not the traditional HD pipes. That's fine though, they will get used to hearing the hi output when they are riding BEHIND me!
You'd probably do better with a D&D Fatcat. The V&H Hi-output was designed for "big" motors, e.g. 116, 124, 131, etc. Using the V&H with your pipe would cost you torque in the low to mid range.
If you look around and find a ProPipe HS and add 02 bungs to it, you'll do better. This was the best pro pipe V&H ever made. There were changes that affected performance on the later models.
