Do I need a new CAT? Options

[ShadowPhantom]

When I first start the car and give it some gas the car sounds like a gurgling terd. Once it warms up it is much less noticeable. Sounds almost like a little marble bouncing around by the exhaust manifold with a bit of a sputtering sound. It only does it when it is in gear not when you rev the motor.

Anyone have any idea what needs to be replaced? CAT or manifold?

If it were sounding more like a rasping/light rattling sound, then I would agree with bindertch on the flezpipe issue. When I first got my gt it was making a sound like that. Replaced the flex-pipe and no more bad sounds.

Maybe it is the flex pipe then. I remember checking it out when I changed the O2 sensor. It looked pretty knarled up. It was so frayed up that it kept poking my hand.

What is the part # and do I need to order it from Toyota? How do you remove and install?

Thanks Again,
Chris

You will probably only be able to order the whole bottom end pipe. It might cost less to just have an exhaust shop put one in. I just looked and it isn't cheap but it is a bolt in part.
