cracked side exhaust

[MillerCobra]

Hi everyone, I had to pull my 427 out for repair and discovered this crack in the one side exhaust. Do you think this can be welded ? The exhaust pipe seems to still have integrity, really not sure what is on the inside or if there is a second pipe inside holding it together. Further, went to the FFR parts page and all exhaust pipes are out of stock.

Can't advise on repairs, but with FFR always email or call to ask about parts availability. Even if they don't have them, they may be able to give you an ETA.

I know that there is an about 2" or 2.5" inside-diameter pipe/baffle inside the side pipes. I don't know if the baffle is welded to the four into one collector. I'm not a welder, but have done a little oxy/acetylene brazing and welding. I wouldnt try to fix it with gas, but your pipes don't look to me to be so rusty or damaged that a skilled welder couldn't put a good bead around it in a few minutes. Nobody will ever notice the repair. If it was me, I'd say this is a good excuse to buy a wire feed welder of your own. Good luck.

Maybe its time to put in your order for stainless Gas 'n pipes? How old are those pipes? They look like they might be getting close to retirement.

It should be weldable but you need to find someone who does it regularly. The metal is fairly thin which makes it difficult to weld it. MIG might work but I'd prefer TIG.

I seemed to remember a few of these failures being posted in the past. If I recall correctly, there was batch of side pipes that had a manufacturing defect. They were stretched too thin at that expansion segment and the bend was too sharp.
I would contact FFR with your date of manufacture and see if they can help you out. If that fails, find a good welding shop and get it repaired. They may have to put a patch on it to find thick enough metal.

Good Luck

I have a set that I'm not going to use. The unpolished ones. Going to sell all the stuff I don't use at some point.

That crack is weldable and as CraigS stated TIG is best for temperature control and filler. This project would be routine with clean metal but there is carbon and fuel deposits inside that can contaminate the weld.
The welding process causes hydrogen embrittlement so assuming the support and vibration inputs will not change, this welded area will crack again.

Find a place that does custom turbo installations. Those type of places typically have people that do beautiful TIG work.

Avalanche that is a good idea.

Those look like stainless ? Are they if so they can be tiged! The big problem is the FFR pipes are very thin and cheaply made. I can fix them but I'm in Wisconsin. These are mine

Bob,

Could an easier solution be simply replacing the mufflers similar a pair like is shown in the link below:

If the mufflers are the problem, then maybe replacing them is a viable solution so with that said, What-Cha-Think?

PS: I can't weld and only make Volcanic Bird Poop even with a Mig-Welder.

Tig weld OK

Steve I've already looked into those but the problems are finding the right size and they don't look like normal side pipes !!

Thanks everyone, this helps!
