I was wondering if any of you guys get a slight rattle/vibration when the car is at idle with the AC on. Once I am on the throttle it disappears.

Is this normal?

 

u have comptech headers?

 

I have a creaking noise from my steering wheel that seems to be worse when the A/C is on. I haven't figured out how that could be correlated. It only makes the sound when turning the wheel. Anyone else have this issue?

 

Yes I have Comptech headers. But I just took my RT Cat. off and put the Stock Cat. on did this occur, when I had my RT Cat. on there was no vibrations

If it is a normal thing I don't mind it, its not that strong (the rattle). I just want to make sure its normal.

 

it appears that this rattle with comptech headers is more common than originally thought, call comptech and report it

 

so with a comptech / rt cat combo you had no rattles?

 

Are you completely sure you didn't have a vibration with the RT cat?

Maybe it has something to do with the heat shield that surrounds the cat as opposed to the one between the cat and the body.

Is there a noticable weight difference between the RT cat and OEM cat?

 

Yea with my RT Cat./ Comptech headers combo, I believe there was a very slight rattle when the AC is on, but goes away after a few seconds.

Yes I believe the RT Cat is lighter than the OEM.

 

RT cat does not produce rattle at all. I had RT cat before the Comptech header and it was fine. But after getting the header on, it started to make noise.
