Let’s see who has the oldest exhaust on their boat,I think I might be in the running,I have dry Stainless Marine that are 32 years old. That’s older then some of you guys on here.

Yup,
dry Stainless Marine 4.5”. 24 years old and are still perfect.

Sounds like a contest for who has the ugliest wife

I have dry CMI Big Tubes - maybe 8 or 9 years old. Flushed for 5-10 minutes after every run. I hope mine last half as long as yours!!

Post of the year?

I work on a few mid 80’s boats with original exhaust. One’s a 84 that stays in the water all season. Maybe missed being used (put in) only 4-5 years ? Other is 87. Other is an 81. Same deal. Both oe merc cast iron.

Much maligned CMI headers on their 15th season. Fresh water only though.

I finally replaced my CMI E-tops after 21 years, 10 of that in salt.

My old 2000- 29 Baja Outlaw- 454 Mag MPI's over 1100 hours totally factory- never even been opened. so 22 yrs old.

Lightning Headers original from 98 so I'm at 24 years. Had them pressure tested and inspected a few years ago, still look new.
