Hardin cyclones

Did some reading and not much input either way especially recently. Is anyone using these or has used these? I currently have Gils and want easier plug access. And maybe something shiny. Just looking for feedback.

Salt water or fresh water? Engine application? PM me all the questions you have as I am very familiar with the Cyclone shorty headers.

I have a set I got used. i havent ran them yet but they look very nicely built. One had a pinhole leak and I repaired it. Pressure tested both with 150psi and it held over night so I called them good. I am really looking forward to running them though.

im already running gils. Can’t see these being worse than gils. Quality and longevity are my concerns.

I think a lot of the issues must be we not flushing with a LOT of volume of water and using salt away/ dawn, granted my E-Tops and not full length runners but they are still in good shape with 7 years of salt running at 20 years total.
Not pushing my luck will replace them after the new years run.
