Pipes

I have a question (or two). When did plastic coated pipes come in? (my understanding is 1990 with the - confusingly - 1991 model range, which also included smoked rear lights on all hatchbacks and the black chin spoiler on the TZD Turbo and TZi/GTi's).

Is it possible to change the older pipes on, say, a 1989 car with the plastic coated ones or is this a waste of time (and too expensive)?

What ORGA number range differentiates the Phase 1 from Phase 2 Mk II BX?

It was simply a change of material - new coated ones simply fit exactly as the uncoated ones did - and if you buy genuine Citroen the come pre-bent and go straight in (unless they are the rear ones which have to be threaded round the subframe.)

The old ones are fine till they rust! If they're good a coat of waxoil will prevent corrosion if you can get it on them!

Most cars will have had the front-rear pipes changed by now. My 89 car needed them in 2000 at about 170,000 miles.

A lot of pipework is visible from under the bonnet, is that shiny and black? or is it a kind of galvanised grey colour?

By far the easiest solution is to bin the steel pipes (coated or not) and replace them with kunifer using stainless unions. Job done. FOREVER.

I was about to say, just get kunifer ones. The plastic coated ones still rust, just not quite as quickly.
