My 390 gained 80 HP when I switched to the CC, 2 1/2 dia x 28" with 3" dia pipes. Packing and open end of the louvers facing the back. Switched out the original Classic Roadster mufflers which were very restrictive. There was also a new intake manifold. I have since upgraded to a 445 with the same pipes...sounds great many compliments.
