Seaward (Hardin Marine) exhaust-gctid823945

[No_Quarter]

Hi, forgive me, this is not for my Bayliner actually, it's for my twin 6.2 MX Baja Outlaw, but I get such good answers here!

The Baja is 15 years old, mine for the last 12 years, always in salt water all season, doesn't get flushed. I think it's time for new exhausts, and would like to take the opportunity to add a few mph. So I'm considering this, with the 1000 hour coating.

Does anybody have any experience with these? With regards to:

-Longevity of alu in salt water

-Better performance

-Simple bolt on

-Weight reduction, how much (two engines), and is there a formula for reduced weight to mph

-Etc

Thanks
