A local shop was able to cut a piece of pipe and weld it in place for around $100 as others suggested.

It's a fine solution to get rid of the noise imo.

* In unrelated news on the way home yesterday I noticed the telltale signs of ANOTHER wheel bearing failing which will be number 5 on this car. In the words of comic book guy from the Simpsons "WORST. CAR. EVER."

I am having the same issue that the left runner behind the driver side header has craked and broken right near the drirvers door. Its annoying as ****, but the pipe is pretty rusted and I dont know if a patch weld will hold. I may look into an aftermarket stainless steel midpipe.

I have a Gs350 awd, and having the same issue right now, and found a tone of cracks and rust.. Sounds like a v8 atm.. Im looking to replace this with an Invidia Midpipe due to stock midpipe costing 2k+ smh. Supposedly this is a common issue... Correct me if im wrong

Common problem best thing to do is what I did and remove the heat shield clamps and the matting all around it. If you dont your other side will rust further. See what the exhaust shop will tell you, no need in wasting money on a mid pipe. imo

You can also use a wire brush and spray it with high temp spray to stop rusting especially for you guys that are up north.

Gs3500

Where are the heat shields that should be removed? Is this something easy to remove?

Same issue on my car...2006 GS300 AWD with 110k miles. Removing the heat shields just got me through the winter though now the pipes are leaking again.

Its seems from what I read here, its either OEM or after market mid-pipe (invidia?) with a custom install.

Gs3500

Does the invidia pipe fit an awd gs?

How about just JB weld to plug up the weld? Assuming it only has a hole or 2

Before the cats on both sides, they like to collect water inside, which is why the pipes rust and leak. Easy to remove i think its a 10mm nut. On mine they were so rusted i had to cut them off. Very easy to remove

Thanks...Are the heat shields that should be removed before or after the O2 sensors? I see shields in both places??
