Can cats be repaired?

[RB_Stu]

Hi all,

I bought a cat of ebay as mine was de-cat'd before i bought it and it turns out its cracked all around the flange

Obviously, ive contacted the seller, and i hope we can come to an amicable agreement regarding a return/refund etc but in the meantime the MOT is looming so im wondering if it turns out matey doesn't want to play ball then could it be repaired?

Problem is thus:

Are they stainless or mild? Wondering if worse case i could MIG up the flange on the inside and dress the outside...

Yeah that could be welded

Its the heat im worried about, will it kill it?

This is mine below and im getting mine fixed for around £30.
Its getting a new flange put on it.

No it'll be fine, welding an exhaust is bread and butter stuff for a lot of places.

you will never weld repair that and get it to seal properly

it can be modded, but it's no good for standard fitment

Iirc cats can't be welded..
.. apparently its cruel and burns the fur.

But on a serious note, should be able to weld a new flange onto it. Then exhaust bandage/paste to make sure its fully sealed?
