I'm looking at 2 used sets of CMI headers - I think they are considered the E-top (2 piece design).
How do you go about testing or checking for leaks?
Are there "do it yourself" kits or do you need to take them to an engine shop or CMI to find out if they are ok?
Do the welded SS headers (regardless of make) typically rot out at the collector flange or on the head side? What happens if a tube is dented and the inside wall contacts the outside - is this destined to be a failure point? Any first hand knowledge? I don't know if they have been used in salt, but would assume thay have been.
thanks for the help.
