have a look on flea will probably find everything a little cheaper and its all pretty simple to put on just a couple of bolts and the parts will probably come with new gaskets to go inbetween the parts aswell

 

I have Rover, but I never changed exaust system with original 'rover' parts, because they were expensive, delivery time consuming (live in Croatia) and I could pass lower in price with same or better quality.
More to this I usually replace my exaust (cat included) with stainless steel parts. My rear box in stainless steel was replaced in 2004 and still working fine with no signs of wear. Warranty period of back box I put was 3 years, and money I paid was 47 GBP.

 

cheers billyrk....

not quite sure what flea is though....

sounds silly, but would a £60.00 centre section from one parts supplier be better than a £50.00 from another....?

thanks again....

 

its all mild steel. personally id fit a stainless system and never have to worry about it again.

the cat will be expensive so if it doesnt need replacing just leave it til it does. if its coming from under the drivers seat chances are its the centre section

 

exhaust

You need to identify where the leak is coming from. I recently did a Rover 25 exhaust. The back box was leaking where the spring hangar was welded on.

Originally I thought I would remove it and weld a patch on. Then I found the middle box was puffing slightly. I bought a middle box and after finding the back box had further bad rust ordered a rear box. You need to undo some very rusty bolts, I use Plus Gas. some undid the last one I cut off with an angle grinder.

Dont forget new pipe gaskets before replacing the system. Make sure the car is safely jacked up and supported.
A friend of mine lost his Son when a car slipped of the jack.

thanks for all ur help people....

i guess a stainless steel system would be more expensive and considering the car is unlikely to see another 40/50k i may just go with a normal system....

how can i check the cat...???

saw a stupid yank on youtube drilling holes before and after the cat and checking pressure.... dont quite fancy that...

give it a wack...?? listen for any rattle...??

if the cat is ok, how difficult would i expect it to be to fit new parts to it...?

again thanks people, much appreciated...

 

If cat rattles when you give a light push, than it is for changing. Also you could hear rattle when car is running from place where cat is positioned on exaust system.

I am not sure if possible in UK, but in Croatia you can make free HC and O2 check on same place where you are doing MOT. This is the most proper solution to check cat system.

For change, like Kels said it could be tricky to undo rusty bolts. I had to cut mine with grinder too. Other things should not be too difficult.

 

get it on axle stands, have a friend rev it and look for where its coming out from underneath.. thats what I did.. could even spray a non-flamable aerosol down the length of the exhaust till you see where its puffing out. I'd suggest buying a new set of nuts and bolts as you might find you have to destroy them lol, need high tensile m10x40 (or longer) bolts, m10 nuts (obviously doesnt need to be nylock that'd just melt).. oh and some penny washers.

Take the car to a tyre and exhaust centre and get a quote (ask for a written quote - usually printed of) use this to source your parts cheaply as you will have whats needed and most times a part number, also you can have a quick look yourself when its up on the ramp...... all totally free of course....they even tell you its a free quote.

Tell them its the wifes car and she wants to see what it will cost first....

Use it.

 

good idea....

took it to a local exhaust centre and they got it up....
after walking around underneath it became apparent that its the back box blowing, well just before that on the pipe leading to the back box... so new rear box it is then.... also the centre centre looks corroded and in bad condition (but not blowing), and the CAT seems fine....

they quoted £204.00 to supply and fit new centre and rear sections... how does that sound....?

for the sake of £100.00 (parts being about £100.00) roughly to fit it, im tempted to let them do it...
also, the area where the centre section connects to the CAT, seems quite far up the car and thought i may struggle to access it with just axle stands on the back wheels...

how long of a job is it...?? i mean, i hate paying for anything i dont have to, and would quite happily sacrifice a saturday, if it means i can save a ton....

does anyone know of any detailed 'how to's' on the net for this job, would come in very handy...

thanks again for all your help... its very much appreciated....!!

 

if the mid section on the zr is the same one off the 200 ive got one at my parents house that i aquired only for the cat that was attached to it and never used the mid section its in good condition with no holes or splits.

only after £10 for it

 

its all pretty straight forward so long as you have the right part.

Exhaust is just made up of sections either bolted together or sleeved together (think theyre all bolted on a rover).. just a case of unbolting and take out, add new gasket, then bolting new part back in. Theyre on rubber hangers that will easily slide off with a bit of grease to help persuade.

Simple in theory of course but sometimes the old nuts and bolts are a bit of a bugger and may need cutting away which is why i suggest having replacements on hand.
