I need real feedback on Proparts semi- fenderwell headers.

I currently have Hooker supercomp BB fenderwell headers.
One pipe is rotting out do to condensation/coolant/bolt leak over time.

Happy with performance but Dont want to spend $600 every 5 years.

Has to be 2" pipes minimum 40" not to hinder performance.

Thanks well in advance.
