what pipe do you think has the biggest header diameter and has the best exhaust flow? Dont care for what it sounds like just want the pipe that will let the most exhaust out.
settled on a 2bros thats shortened to 6 1/2 inches
wanna throw a 4.1 on my pitster. Its got a jialing, with a 146 kit and a TB race head...... not sure what pipe would fit it, anyone know?
