I know this is a loaded question, but I have a Suzuki M109R that I put a 3" in / 5" out Supertrapp muffler on. So far I like the sound and performance doesn't seem tom have taken much of a hit. My question is for an 1800CC V-twin with an RPM limit of 7200, how many disks should be good for top end performance? I have 12 installed now, but it seems restrictive from about 5500 RPM and up. The # I have heard befor was about 18-20, but I'm looking for more feedback.

I would pick up another 6 pack of discs and tune by adding two at a time.
