Thats cool tagalong. Whatever your happy with. However it has been proven in dyno tests and with hours and hours of track testing that particular pipes do work better on certain motors - there is no denying it

In the GO range of engines the pipes that shine have been proven to be:
3 Port - 086 or 0801
5 Port - 086 or 0801
7 Port - 053 or 0801 or 2047 with 0801 header
If you want to get the absolute best out of your motor, you probably should be running one of the pipes above, especially for the economy side of things as well.
You can always tame down the bottom end etc if you need to with clutch / restrictor / exponential settings and so on. It just seems a shame to me to have a screaming top end 7 Port and stifle it with a bottom end pipe
