If they are the Victory branded pipes (not RPW or Bassani), they are one of the most restrictive pipes you can have.
With my pipes (which are better than yours but still suck), we gained 1hp and lost 1lbs tq by pulling the baffles. When we pulled the tips off too, we picked up 5hp EVERYWHERE on the dyno curve. The pipes I have are still choking my bike to death though. My horsepower peaks at 4,500rpm and flatlines all the way to the 6,500rpm over-rev.
2007 Hammer, 260 Metz, Shotgun exhaust, S3 cams, LED hidden turn signals, HID Hi/lo headlights, a few Ness accessories, S&S intake, PC3, and dyno tune.
