These just came off my 21' Ultra. One of the primary tubes started leaking so I replaced them. The internal pipe is stainless so they should be good once you repair the damaged tube. I can't promise another wont leak, but I figured someone might want to save a couple grand and try repairing these. No other signs of corrosion anywhere else that I can see.
These come with 2" primary tubes and a 4" collector. Powder coated candy blue. Water rails, elbows, hose and everything else needed to install minus the house clamps(I needed those) and gaskets.
Asking $200 for them. These can be picked up from my home in Costa Mesa or my office in Diamond Bar.
