Default Exhaust clamps

My exhaust is about one year old. And I've noticed how the clamps are rusting and obviously do not want that rust to carry over to the pipes. Summit has stainless clamps



But my question is I've seen so many cheap rusted stainless fasteners I wonder with heat and time if they'll do the same? Do you know of any good clamps that will not rust?

clamps are teh suck, they crush the pipes. A proper exhaust is either fully welded, has slip joints secured by tabs or flanges. DIOADIR

This is what I have used in the past. These work great are reusable and don't rust. They also don't crush the pipe.

I have two of these where the exhaust breaks after the crossmember but they used two cheap pipe clamps further down by the mufflers. Thanks I'll go to that.

I suppose that depends what type of environment it's in. I have a 409SS system (for sale if anyone's interested) that has no rust or scale- just a slight shiny purplish discolourization-looks rather attractive. Sections are held together with 304SS clamps I picked up at Carlisle- no crushing or any other problems. No need to tighten the crap out of the clamps-use exhaust pipe putty to seal the joints before slipping the pipe sections together and everything is fine.

those band clamps are the ticket, they don't rust, they look nice and best of all they don't crush the pipes. With the other ones, sure you don't have to tighten the snot out of them but stainless does expand with heat and if you use the clamps to " clock" your mufflers and they keep sagging you do need to tighten them quite a bit which can lead to crushing the pipe.

409 will not form a rust layer if you keep polishing it every now and then but after several years you will see that it starts to form a scale. the original 81,82 and c4 headers are 409 stainless, just check out a 20y/o pair of those.

This is a set of C4 ones (pic off ebay)


The reason this stuff is used is 1st it's cheap and secondly it can withstand very high temps (often you see cat cons made from this also(, they could also use inconel but that stuff is $$$$$ and difficult to work with.
