Replacing exhaust flexis
Both my exhaust flexis between the cats are damaged right through and now leaking. With MOT time coming up I will need to replace them.
Anyone know where is best to buy the replacement flexis?
What grade of steel is the exhaust so I know what filler wire to get for my mig?
Ta much

Re: Replacing exhaust flexis
Instead of putting new flexis back on why not weld in stainless steel pipes hence no corrosion ever again and better air flow!!!

Re: Replacing exhaust flexis
Id prefer to stick flexis in again so I dont have any potential vibration related cracks forming

Ye your right!! I need to locate flexis too I've found a place in Liverpool that I've spoken too but they need dimensions and OD have you got the dimensions and spec etc??

Re: Replacing exhaust flexis
i had mine checked at a local (ish) exhaust specialist, he was going to charge £150 all in to replace both but he was good enough to be honest and said although slightly scuffed/damaged they weren't leaking so he said not to bother

Re: Replacing exhaust flexis
Not sure on the dimensions of them, 2.5" diameter is all I know at the moment. Im offshore at the moment so will have to have a look when I get home.
Mine are definitely holed right through so will fail an MOT.
Anyone know what grade of stainless welding wire is all right to use to a varied range of stainless grades?
