Astra H 2008 petrol manual
Daughter in London rings up concerned about 'new noise'. Quickfit tells her it is blowing exhaust, quotes £440 to replace. That sounds hot to me, is that reasonable?
-
£440 might be ok for a full front to back exhaust, but does she really need that?
-
An Omega exhaust costs about £250 fitted. You do the maths...
Joking aside, National Tyre may be a better bet than Kwikfit, and it could be a good life lesson for her to shop around and get it fixed ;)
-

you think that after 12 years, only one section of the exhaust will have rotted?

I think that Kwik fit are a bunch of cowboys and would replace it whether it was needed or not.

most mechanics prefer to fit an entire system in one go, rather than 3 separate visits from an increasingly irrate customer over the next seven months.

National tyres quoted me over £200 for a complete exhaust for my daughter's Siecento .... which was about all the car was worth .... even Fiat themselves quoted less.
I bought one from a motorfactors for about £35 .... though it did take 3 attempts to get the right one ;)
-
Complete cat back setup is circa £100 delivered from the usual suspects (e.g. as per the Omega V6 suppliers)
Not hard to change usually either (front pipe to cat nuts being the worst bit)
-
Thanks to all for advice. Cheapest cat is about £100, cheapest exhaust system again about £100.I will let daughter enquire if quote is complete system or cat back, and price from National Tyes. Have members any experience of detaching cat section from cylinder head? I have had bad experiences detaching exhaust manifolds from 2.0 Omega cylinder heads.
-
I have changed one Astra H exhaust system, cat back. I changed all 3 sections, could not easily separate the sections, so cut it up with an angle grinder. I imagine that is what Quickfit were quoting, the cat should be all right, and looks quite difficult to remove from the head. As said above, trickiest bit was undoing the 3 bolts holding flexi section to catalyst.
I see no harm in letting daughter carry on using the car as it is until Easter, then bringing it home for the fitting of 3 new rear sections.
Has anyone removed the catalyst from an Astra? I see from e-bay pictures that the cat bolts direct to the head. Do the bolts unscrew easily from the head? I ask because I have a donor car in my drive. Is the cat worth saving?

I thought you were cutting the apron strings Terry ..... :-\ :-\ ::)

:-X
On several points.
-
the cat is a manicat ,exhaust outlet manifold and cat combined
your best to keep the original cat ,unless it's damaged ,not working
the flexi joint on the front pipe is a common fail point
about £30 -£35
rear box is stainless IIRC
I've only ever had to replace the front pipe ,which has a post cat lambda
a local garage would probably replace the front pipe (if that is the only issue) for circa £120
example clicky £31.71 (https://www.ebay.co.uk/itm/1x-KLARIUS-OE-Quality-Replacement-Exhaust-Pipe-Exhaust-For-OPEL-VAUXHALL-Petrol/191589224951?fits=Model%3AAstra+H%7CCars+Type%3A1.6&epid=1837507152&hash=item2c9b9b91f7:g:He4AAOSwstxVZawF)

Thanks Dave. That's not how I remember it. I don't recall the post cat lambda in the front pipe. What year did that come in? Son Ben's 2006 Astra H should be here tomorrow, I will have a look. On the one I changed, the pipe went over the rear axle, and as I could not separate the 2 rear sections I had to cut it in two to remove it. Cath's car is a 2008, Jonny's is a 2010, the donor is 2004. I forget which one I changed the exhaust on. I fear it was the 2008 estate wrecked in London, insurer paid me £2000.
-
Checking my records, I did not record which car I fitted the new exhaust to - very careless. I did note that at its MOT in April 2019 Cath's 2008 Astra had a blowing exhaust flexi joint, so no surprise that now it's noisy - I bought it in July 2019. I must check whether the new exhaust is on the donor car.

The Cat I expect will be fine, there is a post cat Lambda sensor, disconnect it and remove with the whole exhaust section, then heat the boss where it screws in and it will wind out with no major challenges. :y

Daylight robbery from Kwik fit, definitely tell her to shop around .

Thanks. I have found a U-tube video describing changing just the front exhaust section, cost £22.50. The lad doing the demonstration broke off a stud ataching the section to the manucat, but otherwise made light work of the job. I could replace the flexi section for £10, but the lambda sensor might inhibit this route.
-
even if you get the front section replaced at a garage ,it's still a lot cheaper than quick s**t doing it for £400
warming up the cat may help with bolt removal

I planned to use heat to facilitate removal of the pipe to manicat bolts, and to remove the lambda sensor. My worry is removing the front pipe from the central pipe. In the video the lad removed the pipe clamp, then grasped the front pipe with a huge pipe wrench and rotate it. I am sure that either that way, or heat, or hacksaw, will achieve it. As you say, I could pay a mechanic to do it. I have three sons, they can do the heavy work.

so spend a bit of time with your lads , drink tea and be the gaffer ,while they do the spannering with your supervision :y
family time and a joint sense of achievement would be far more satisfying than paying a big bill from quicks**t ;D

now you know why ANYONE who expects to fit exhausts for money has oxy-acetylene. This means they can heat up the nuts to the manifold before trying to undo them. Those are the only nuts to undo, as the rest of the system is removed complete, or burnt into sections as necessary. Replacing just a part of an exhaust system rarely works for long. An experienced exhaust fitter would have the entire new system on your Astra in minutes.
