No rhyme or reason is required in La La Land.

it's because you move the cats which changes the efficiency

i have used shorties and long tubes. For the money and return if you can do your own work shorties will work well for your situation. I got 16 hp from my set up, pacesetters. Sounded good, dropped some weight. Good torque gains too.

After I went to H/C the shorties were holding me back, so then I switched.

best input is from those who have experienced both set ups.

Good luck
