tunertom · DTR Senior Member

are they made of steel? obviously plated?

thanks

Ralzy · Guru

I think they are made of Stainless Steel mate not sure on the welding sides as i never had to weld one

Calum122 · Guru

No. Dep pipes rust. Therefore not steel.

Calum122 · Guru

True. But they're pretty weak and light.

that doesnt make sense, steel rusts like a mother f*cker

Ralzy · Guru

I agree on that with you Calum. You would think DEP would state on their website the metal used wouldn`t you or did i miss it in their discription ?

easy to check if something is steel or stainlessteel use a magnet it will not stick to stainlesteel .

think they are just chrome plated and like most zausts are made from cheap steals that will break down or rust easy

as for welding it will be possible but would not use arc on some parts woul just blow holes mig welding is much better .

Ralzy · Guru

Yeah thats a good idea with the magnet method MDK

I think this may help confirm the metal

Steel is a combination of iron isn't it. Therefore it's magnetic.

ive had one welded up where it rusted thin and got several holes

MDK · DTR Legend

test this at home raid the cuttlery draw .. magnets dont stick to true stainless steel .

that been said there are other types of lower grade stainless steel that maybe magnetic .

but knowing from a scrap man point of view if a magnet sticks it.s not stainless and weighs in as normal steel

EVERY single DEP pipe that ive had, has had a tiny pinhead hole in it from factory, got 2 DT pipes here, both have a small crack/hole in them about 1mm/2mm, will only cost £5 to get both done at a garage but its inconvienient...

always check your dep, by covering one end and blowing into the other, then listen for air leaks, because mine all have tiny holes or cracks in that obviously arent meant to be there

DEP front pipes are utter chav garbage tat, I think they are made from old Chinese bean tins or something. Ive bought one new one years ago but never again. Tailpipes are OK though.

MDK · DTR Legend

1DOWN5UP · DTR Respected Member

Matter of personal opinion Scrim, mines been good for me, you just need to look after them mate, the fact is most people can't be arsed to bang on some ACF-50 or similar now and again, then complain that they're rusted to fook, and flog them on, which is fine by me as I know I can bring them back to how they should be, after an hour with a wire brush drill attachment, some t-cut, and a sheepskin polishing disc.
