Lake Okanagan used to be a great place for any high HP boat. Now they're on like donkey kong with anyone with dry exhausts that's reverberate from Peachland to Penticton. Buddy of mine only launches his triple engined boat at the Richmond launch next to the airport,LOL.
I's freaking loud and sounds like an airplane on takeoff. http://www.youtube.com/watch?v=F9VCdKpoh1Q
How's your transom repair going?

Here is a cutaway pic of when I made the headers. They are all 31 to 32 inches in length with a 4 into 2 into 1 collector.
Typically it performed like any good 2 X 32 header with frequently a little extra torque around 3600 to 4400 rpm because the 4-2-1 collectors which typically broaden the torque band. The runners actually have an oval profile with an area equal to a 2" round header. Currently we are using them on 1250 HP motors.

I'm really not sure, you would have to contact Diamond Performace. From everyone I have spoken to that's owned these long term, they all love them and couldn't be happier. They were also used in some race boats and are known for their raw durability.
