Next issue, my dyno guy calls me AT WORK today, on Sunday cause it's buggin' him too. He asked if I remember which pipes we had running out the wall. He said we might have used some 8 inchers that he was using to dyno some blown alcohol thing earlier in the week. He usually runs a 4 inch pipe from the header through the wall. Said if we did, that may have a LOT to do with the numbers. Especially torque.
I happen to take a couple pics that day and sure as hell those pipes don't look like 4 inchers coming off the header. Can that really make much difference?
