I'll say that the 30whp I gained with the PPE's and exhaust untuned is a good indicator of it's performance. There was no break in or learning period, it was installed and dyno'd immediately after. Every Momentum header dyno I've seen has been tuned. I think the whole argument is nonsense though. We are fighting over peak numbers and haven't even looked at the rest. Both the PPE and Momentum collector are very similar. The other differences are the stepped design and physical length of the pipes before merging. PPE's are matched to the RPM of the engine. Momentum headers are amazing though, I'm just have a difficult time believing that it would outperform the PPE's given the same conditions.
