Then you will find myths about better heaters in them, but there is little real evidence to support that claim.
At any rate, the extensions aren't rubbing on the exhaust and getting melted or anything right? Also I suppose there is the somewhat unlikely possibility that the heater circuit is damaged on the wire harness.
If you are going to go out and get new ones might as well get the Vette ones and cutout the extensions. If it works then good. If it is an extension problem or a O2 problem that should take care of it.
