Damn noisy cats!
 

I have been having this wierd noise coming from the exhaust, I thought it was just a clamp or something, turns out it is one of the cat converters. Anyone have a set of used cats they want to get rid of?

What kind of noise?
 

Kind of a ringing noise if you tach it up when it's parked? That's what I got. I've been under the car and the best I could come up with is it's the cat. But I've never been sure enough....

I have a pair, Rob...

Awesome!
 

Send me an email and let me know what you need for them!

Kind of a vibrating sound...like baseball cards in your bike spokes...
 

It is always there, at idle and when driving. It gets quiter when the car is warm and I am driving, or at least you don't notice it as much.
