My goal is to have big torque with the parts I have collected. The Fat Cat has the longer primary for a boost in low and mid range punch. Moving up to the Borzilla with it's 2 in. primary may kill some of the down low torque I want. I would love to spend several days on a dyno testing pipes but it would be cost prohibitive.
Bottom line I guess is to pick your poison and live with it.
I bought a new SE case to work with so I wouldn't have the bike down any longer than necessary. Gotta take advantage of these sunny NW days when ever I can.
