Message	I have noticed in the last month or so a hand full of people wanted to know the difference going from the SZ 2.5 super splits to 3 inch expansions. I picked two random points off the dyno. Before mods: GT600R, 2.5 super split, 2.3 test pipes with punched out cats. After mods: GT600R, 3 inch expansions, 3 inch test pipes. At 3,500 RPM gained 19 whp, 31 torque, 5,000 RPM 28 whp 22 torque. After switching to the 3 inch system, it started to make boost at the same RPM, but it spooled noticeable faster. Just wanted to share my findings
