Annoying Noise Coming from bottom of Car
Hey guys. I have a 98' Lexus GS300 and its starting to make a weird noise that comes from under the car. I cant quite put my finger on it. I
t makes a lil bit of noise while idling but not always. However during acceleration from stop to about 35 mph, or while traveling at slow speeds, it makes this annoying rattling noise. Any clue?? I'd appreciate anything you guys can give me. I'm thinking Muffler maybe, but not sure.

LOL - the heatshield is the metal cover that goes over your cats and probably some other parts of your exhaust system. It is there due to the heat - thus a heatshield. It really isn't necessary to keep it on there.
Look at your cats and look at the piece of metal surrounding it. That's it.

Okay, so i'm gonna piggy back a bit off of this thread but i think it's relevant.. .if he does have bad cats and has over 80k miles and does not want to pay thousands thru lexus to replace his cats, what are his options? (I'm relating this a bit to me too ). Has anyone used aftermarket cats, if so, from where? How much?
