Any power loss?

over gils I highly doubt there would be. From a long tube sweeper style yes. It’s pure runner length.

Never ran them In comparison with the gils. They were an upgrade when I built my 565's. I knew i wasn't keeping my 35, so I didn't want to spend a ton on complete new exhaust. We made good power with them over 750. I would use them again if I didn't want to do completely new.

how long have you had them? I’m really thinking this is the route I will go. Don’t wanna drop a fortune on all new stuff. My tails are already fairly new.

I have been eyeing these also. What do you think will be the most reliable in the long run cyclone, cmi fusion or eddie marine manifolds?

if you already have gils these seem like the best bet. You don’t need new risers/tails.

I bought them in 2009 for use in the 2010 boating season
