I mean the baseline at 284RWHP was in similar conditions to the 294RWHP and may only account for a 1-2RWHP difference.

Yeah there are a few things to consider. First, the baseline was performed with high flow cats which free up a lot of the bottleneck in the exhaust already. If this exhaust were tested with the stock cats, the overall numbers would be lower but the gains would most likely be bigger (law of diminishing returns). Also consider that this is just one design we are testing. Berk is almost sure the X-Pipe will make more power than the H-Pipe. We will test the X-Pipe hopefully tomorrow afternoon.
