Your cat is under warranty for 80K miles mandated by federal EPA
requirements. If I'm not mistaken only dealers are allowed to exchange your
cat under this federal warranty governed by the EPA. Headers cannot cause a
cat to go bad. Sheesh. The wrong kind of fuel or fuel additive will
destroy a cat. Worse case scenario, have your dealer replace the cat using
clamps, then take it to a reputable muffler shop to do the required welding.
I had talked to a muffler shop some time ago and inquired about an HP cat.
They were the same people that installed my Borla cat-back system. They
told me they wouldn't touch that with a ten-foot pole....unless I had at
least 80K miles on the truck.

Subject: DML: rattling cat?
I have developed a rattling sound under my 99 R/T and at first I thought
from the
sound it might have been a heat shield but after crawling under the truck
with it
running, I could tell the sound was coming from the area of the cat and
pushing on
the heat shields did not stop the noise. It sounds just like it is coming
from
inside the cat. Anyone else? If this is true than the cat can be replaced
legally?
The truck is still under warranty unless the dealer says the Mopar headers
which
weld to the cat could have caused the failure. They have been on the truck
for over
20k miles and the noise just started. My dealer can not change the cat
because they
do not do exhaust work and have no welding equipment. I wonder if i can use
a HP
cat of some kind or is there an application for the 99 R/T with the dual
inlet? I
am sure someone on this group knows!
