Has anyone ever heard or had a RT Cat start rattling? I think the core material has disbonded from the casing.....i check all the bolts......its not the flex section on my budget after all.

Yeah search. I had a post about this problem.

 

my rt cat makes that bees in a can type of rattling only during start up. after the car warms up, i don't hear it anymore.

 

Sounds like you may have a loose heat shield.....

 

yes, the honeycomb lookin stuff in the rt cat came aa.."unglued" and started to rattle


i took it back to the place i got it from and got a refund

 

My RT Cat problem

I since sold it and replaced it with a test pipe.

 

straight pipe all the way!!!

 

This is what im going to do....funk that thing. Ill get a old from a junk yard for inspection....or pay a "Special" place to do it

EDIT: of course...it doesnt even have 1000 miles on it....

What a POS

 

Of course my main exhaust hanger (0the one the supports the Cat) is half broken.....this might be the problem. Even tho the bolts are tight if i support the cat just a bit more or old the flanges the noise seems to go away.....

Regardless....ill replaces the hanger....being that this section of exhaust is under alot of stress when under hard acceleration...45$....no big deal I suppose.

Still going to get a test pipe tho!

Only like $25 from Warpspeed.

 

Cool.....wonder how long it will take to get it.......

 

Not long at all.

 

Test pipes are evil .

 

hehe seems to be about 50/50 who has problems with them.

Well I just picked up a new cat support bracket.... 48$...nice and shiny zinc coating.....might as well fix it right. If this doesnt fix the rattle and the cat is indeed self destructing ill send it back to opt auto or rt.....and go with a straight pipe.

Man I hate messing with exhaust systems.....

Though with out the rattle...it sound so mean
