hi, I currently have a waveblaster that is running a 760 waveraider motor with 701 head. I want to install an exhaust on waveblaster as well as an Ada head and v force reeds. Which factory pipe exhaust works best for this setup, mod or limited? I also plan on changing the motor to a 772 cc freestyle ported motor with Ada head, jetnetics flywheel, and v force reeds. Which factory pipe exhaust would work the best with that setup? I am looking for more low end power. I have heard conflicting opinions on which exhaust works best with setup for most low end power. Thank you.
