Wow, thanks guys. I just assumed it wasnt stainless due to the finish. Looked closer to aluminized. Sweet, havent played with stainless much, but have plenty of stainless rod and plate to play with.
The over axle pipes are all that you should have to replace. They disconnect at the H. If you have your mufflers off check the thickness on the ends. I don't know what its made out of but my exhaust is covered in surface rust. Made it a pain in the ass to put LT's on, thats for sure! If it were me I would just get a new cat back exhaust set up.
Yah, I am really just looking to repair the over axles for real cheap, I'll probably just weld a wire and use a slide hammer to pull them back out a tad. I plan on leaving pretty much the entire exhaust stock, I am just going to relocate the cats to the H-pipe and then put a set of electric cutouts just before them.
The over axle pipe are compressed in that spot stock so that they dont rub the axle. Are you sure you did it and its not just the stock compression spot? And even if they are compressed more than the stock would be m the opening is still the same size weather its compressed or not.
Yah, I looked into that, and it seems they are compressed a little bit more than stock. What makes me really think that is that each side is compressed a slightly different amount. And actually, the further out of round they are, the less flow area they have. An oval with the same circumfrence as a circle will have less area. And beyond that, a change in the shape of the pipe causes some odd behavior in the fluid dynamics of the system, creating turbulence.
It will weld just fine with a standard steel mig wire. I use L-56 wire.
MIG!! Mig is for hacks! Haha, just kidding. I just happen to love TIG. Hard to produce a perfect stacked dime bead on titanium with a MIG welder.
The entire OEM exhaust (minus the manifolds) is 409 stainless.
What about the manifolds? Like I said, I am looking to relocate the cats, is the tubing the runs to them 409 stainless as well?
