How much better are headers than jacketed logs?
Are logs better flowing than a manifold on a car?
Is there a performance difference between thru hull and OT headers?
The reason for the q's is that I am tossing around the idea of going with headers instead of the losg I have now, but I have a nice hood over my engine and would prefer to keep it. If thru transom headers do not make a big difference over the logs, then why waste my money.
Thanks for any info, Dan
