My Type 4 mechanic recommend throwing away my stock exhaust (which included a catalytic converter) in favor of a Bugpack header & muffler combo.  Not only in the interest of power, but apparently for lower cylinder head temps.

Since I added the CHT guage after the exhaust upgrade, I can't be too sure of this.

Outside temp during trip ~ 50 degs.
1 hour long trip.
Full loaded w/ family of four and full propane & water tanks.
Downshifting to third under 55mph.

Sounds excellent to me. With a load on my baywindow pulls 375-420 degrees. A vanagon has the same type4 engine as my bus, so 450 is tolerable, sustained driving above 475 is to be avoided.




Happy Trails,

Took my second camping trip in my 82 Westy ever.  This time around I had a CHT guage added.  On the highway it would be between 300 and 400 degs.  Never quite reaching 400 - hovering normally around 350 degs.  375 when climbing hills or driving at 70 mph down the HOV lane.


 Is that normal?  My Bug mechanic says high should be 375 for a Bug.


 Anyone getting similar results??
