Hey people! I have a 2004 with an exhaust leak in front on that flexy looking piece of pipe that has the mesh wrap, know what I'm talking about? The mesh is off and there are holes in it. Exhaust smell is really bad inside vehicle. I've fixed many exhaust leaks either by "Mickey mouse" or welding or whatever. I have never had to fix this part before. Right now replacing it isn't an option. Has anyone patched or taped this thing up with any success? If so what did you use? TIA.

No. It's not a flat surface. It's flex so it's an "accordion" looking pipe. It will have to be wrapped. I'm just wondering what others may have used. I guess I'll just buy some exhaust repair crap and give it a go! LoL

Obviously your entire exhaust system needs to be inspected by a professional and repaired properly. If your going to keep driving it without a proper repair job, there is some stuff called Exhaust Wrap. This is not a long term solution. This may improve your situation and save you a few brain cells. Carbon Monoxide inside your car can kill. I recommend that you don't use the vehicle until it's fixed properly.

I know this. I have replaced whole exhaust systems so I'm not new to this, but I have never repaired this type of pipe. I'm just looking for a quick fix until I can cut and weld. I was hoping someone had some luck and could recommend a certain product.

That is called a flex section. You can get a new stainless section welded in, but it cannot be soldered or wrapped.

The best way to repair this flex pipe problem is to replace it with a new front pipe. Front pipe is available from Walker but OEM is somewhat more expense. The biggest obstacle is loosening the bolts which are rusty and likely to crumble or snap. Temporarily I have covered the broken mesh part of the flex with some metal flashing and clamps.
One thing I don't recommend is visiting a nation-wide chain muffler shop who will cut off the old flex and unsuccessfully weld in a new one. In the attached picture I used an inspection mirror to look down upon this half-assed weld job that was subsequently covered with exhaust putty that blew off.

Thanks. I realize it needs to be replaced. The new pipe is on order. As I said, I was looking for something temporary to just keep the smell down. I wrapped it in metal tape and that did a good job. I plan on replacing the whole pipe. It's an easy job and I'm not too worried about it. The nuts on the flange at the cat are the only ones in tough shape, but I'll just cut those. Thanks

Your not supposed to look that close! Lol but ya, going back with new is always better. These shops want to get you in and out quick. There are some videos on YouTube that can help in getting those rusty deteriated bolts out. Heat up with a torch then a rapid cool down with water and hit with an impact looks like a good method. If your not in a hurry and you don't have a torch, I've had success with brake fluid as a penetrating lubricant, but sometimes the bolts are just to far gone.

I was told that Walker now uses aluminized steel flanges on their SS Y-pipes. Magnaflow uses full-SS.
