The tests at GT thunder are skewed against the big gun it was a Early pipe. Mike has improved port alignment alot and this was their big problem on the early pipes. Also they really stressed hp in these tests and torque is what Big Gun is designed for. The Big Gun Is Probably the best pipe for a stock engine with a K&N and air box modded. I have a DMC and can feel a HP diffrence over my Big Gun on the top end.
