Yea buddy of mine killed a motor with them headers water water sucked in motor...... put cmi on all good....

Buddy of mine has been running Lightnings for over 14 years in freshwater with no problems whatsoever. Going to be running a set on mine too. Pressure testing them just to be sure, but that is something you should do with any exhaust header system every few year, IMO.

Cool yea the water dumps in his where why to high up in the pipe. His CMI are way lower in the pipes.
