Default Hardin Seaward 525 replacement exhaust
Does anyone have any direct experience with these yet? Looking to swap out some CMI's.

Thank you, I’ve seen the pics, curious how they held up, any power differences noticed? Lost mph?

I know..... but $15k for headers, that will leak in a few years I’m good. I’ll add some lights or something.

You will most certainly lose power. I think with those style exhaust I read it made right around 510-515 on the Dyno in full marine trim Vs the 540ish they usually produce.
