1996 Cirrus noise source found

[Jim]

I found a fatigue crack in the metal bellows in the crossover exhaust
pipe going from the front to the rear of the engine. The crack went
about halfway around the bellows and was fairly tight with little
apparent leakage. Auto Zone and Pep Boys do not sell just a bellows
repair kit. I got a price on the entire pipe assembly. After regaining
conciousness, I called a friend who operates an auto repair facility
with on site manufacturing of exhaust systems a specialty. He cut off
the cracked bellows and welded in a replacement. Total cost $100. The
"moan" sound is gone.

I have a "moan" or "howl" that seems to be throttle related. It comes
and goes as the speed of the incoming air changes with different power
outputs. It is sometimes heard even at idle after a cold start. The
engine is a Mitsu 2.5 V6 with Holley fuel injection. Holley says they
have no product support as this unit was built to Chrysler
specifications. The last time we had it back to the dealer for service
we asked for this problem to be eliminated. It wasn't. The dealer
claimed they didn't have an "A" technician available to do it. That
must mean that our other service items were done by underqualified
mechanics. Very Comforting. Does anyone have this problem and/or know
of a fix for it?

I can't imagine the noise. You focus on the air and fuel systems; are
you
sure of that? Could it be exhaust system?

Sounds like you should find a different dealer for service.
