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.

Happy Trails,

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??
