Exhaust down pipe

[Riley26]

Is it an expensive job to replace what I believe is called the exhaust downpipe. That runs from the small engine manifold to the cat convertor?

[Clarkedontgo]

Depends what car it is in

[Riley26]

Is that a black exhaust bandage around that?

[Riley26]

There is no sensors on this section of the exhaust. It's an old suzuki swift 51 plate. The rest of the exhaust was replaced 5 years ago and is all good. The car has been totally bulletproof had for 6 years. So keen to keep it going.

It looks effective

I've used it previously on downpipes and it lasted about 3 years. So probably a waste of time and money.

It will be buttons then

Does the fact its nearly 20 years old make a difference. Getting it off etc?

Supposed to be "insulation wrap", keeping heat in the exhaust and out of the engine.

Probably snake oil

It does help keep heat in the exhaust, but a side effect of these wraps is they tend to accelerate corrosion of the exhaust pipe.

If stuff is rusted and seized....very much so. And then it depends on how difficult access is too.

[Riley26]

I think access is easy. Will just be the seized and rusted part that could be the problem. Because of this would a garage struggle giving a price?

I wouldn't use any wrap on a 'precious', difficult to replace, manifold.

I've found that wrapping in ordinary glassfibre wrap causes accelerated erosion of the pipes, great flakes of corroded metal come off when you remove the wrap. I've assumed that it's caused by anoxic corrosion, as the flakes are black, iron (II) oxide, Fe203, not the red/brown rust of Fe(II) oxide, whihc fits with the pipes being enclosed.

I really don't understand why some post on other people's posts with totally irrelevant pictures of a shiny rear section and tailpipe that no-one will ever see and words like "because v6" I mean really? maybe they are proud of it

OP the garage should have no difficulty fitting the front pipe and it will probably cost you £150 all in, the part is around £40-50 plus new bolts and gaskets and an hours labour.

Why ?

The wrap absorbs water in wet conditions and the pipe runs hotter, speeding up oxidation. The higher temperatures can also encourage cracking on stainless pipes.
