If you're happy with noise dB..then dry would be better. Otherwise, right at the joint for the stainless downturns would work. Assuming the risers go through the transom? Not sure how much benefit you would have using a megaphone collector. You basically only have a collector after the new 'header', so not a lot of restriction before it sees atmosphere. The amount of time you would be at full throttle is less than 10%. |
