No , unless wrap / header see alot of mositure (water) and salt ....which decreases life of all exhausts parts .....Is this true on heat wrapped headers? it significantly decreases the life of a header...
My headers are wrapped from the previous owner and I've had it on my car for a while now....should I be concern? I haven't done anything to them since the install except spray DEI on them.
which is why your headers were not wrapped all the way down to include y pipe.....
