Hi all-

Recently I have been considering replacing the rusty heat exchangers in
my 82 westy with bypass "J" pipes.  My van is primarily a Warm weather
vehicle so heat is not a concern.  Has anyone had experience with these
pipes. The other thing, should I be worried about the engine running
hotter without heat exchangers.  How will it affect windshield
defrosting abilities on the not so hot, rainy days.  Last thing, will I
still be able to use the Gas heater without heat exchangers.
Thanks in advance or any help
