Yes, they are +3 Viper long travels. They cost $750. I couldn't tell you how the pipe performs, my sponsors gave me a huge discount on it when I bought the machine, so I already had it installed before I rode it. I've seen dyno charts that show it added 14hp total (full system, GYT-R jet kit, GYT-R air filter, and removed lid.) I wish I had ridden it before I put the pipe on there though.
