PostPosted: Mon Nov 20, 2017 3:03 pm    Post subject: You wanna replace all the old exhaust fittings on your car? Reply with quote

Really, do ya?

Bumper stays were shot on my 993. Basically the only thing holding the bumper on was four screws. :Surprised: So whilst in there, may as well change rusted and knackered other bits of the exhaust system whilst the bumpers off.

Oh what fun it is, browsing the PET catalogue coffee in hand, pencil and paper jotting down part numbers.

Then there's the call to your local OPC and scouring Eurocarparts etc etc.

I ended up replacing the following:

Bumper Stays, CAT headshield, small heatshield in front of CAT,Silencer straps, every single clamp from the heat exchangers back, also the CAT straps plus every nut, bolt and washer to go with the lot of it.

Total cost of parts £1K. what

Plus around 30 hours of labour.

Thankfully the main heat shield that's hidden behind the bumper had only a tiny amount of rust and that was only around the lower btm edge fixing points where it was bolted to the car. So in this instance larger washers were used as it was 99% complete and in good order.

The nearside heat shield above and in front of the silencer was repairable as it was only its leading front edge that was rotton. (Repaired by cutting up the good metal left off the original CAT shield, the offside one was fine.

There was no rust in the chassis legs at all, (we removed the the silencer heatshield to have a poke about), other than surface rust on the outer seams as seen in the pictures. Behind the removalable bumper impact stops, the chassis legs were like new inside, but we waxyoiled them anyway and sealed back up.

Sorry I seem not able to add more photos, and the ones that have uploaded arn't in sequence. nooo

WTF. MODS Help. What's it doing here? It's supposed to be in the 993 section.

Did you take the right angled plates off and the bumper supports? The chassis leg corrosion is hidden behind those plates.

Great work and costs sound about right and you've managed to get away with some big ticket items like the rear PU heat shiel, there's also heat shields either side that insert into the rear PU which can be rotten, or they were on mine.

Labour of 30hrs would give a cost of £1500 at £50hr rate, ouch, I assume you got some mates rates in that respect.

Your 4th photo down is not a good view of the chassis leg, in fact the very rear edge of the leg does look rusty. As Endoman suggests you need to remove the angled heat shield held on by a couple of 10mm nuts and all will be revealed.

Good work Wozy Thumb

When I had my rear end off Very Happy I too found a 4 digit number on the metal work. Also you can see the areas that I checked for the deadly chassis leg issue. You can see the heatshield, bumper support cavity and the plate are all in good shape as is my big heatshiild. My car having spent the first 15 years of its life in the ME and then the last 7 in Spain has made a big difference to the degree of rusting even my bumper supports only needed sanding down and repainting.

It gives a great deal of satisfaction doing this sort of work thumbsup

Yes, we moved the lot .... just can't add extra pics to show it. There was rust on the leading seams, but looks worse in the pic than actually was, no rot just surface rust. Considering the state of the bumper brackets I'd expected the worse, but all was ok. We treated this area with sand back, primer and paint and waxyoil.
I've always been a believer that chassis leg rot affects some cars but not all. Why not I'm not sure. Mine is a very early car, and there is signs of paint behind brackets, there was lots of crud, but minimal light rust. No idea why, maybe the initial batch were built a little different as they came off the line.

Yes, I wasn't expected that to be done. They do look better for it though, they were minging and I wouldn't have bothered to have them cleaned up .... if they could have been.

It must be remembered this is a car to me, a lovely one but not to be a pristine 911. I'm not a Jackal type (though nothing wrong with that) that feels the need to make the underside of a car pristine . I like driving them in all weathers too much Smile

Did you replace the nuts & bolts with the OEM steel items, or go stainless?

Very handy post because, as you know, I am about to do the same. I had budgeted circa 3-4K for the works so we’ll see! I’ll also be whacking on some new mufflers. Nurse!

Excellent, I'm glad the chassis legs were good to go, I've seen examples where new metal sheet fabrication was required.

I've also gone OEM nuts and bolts, I guess they lasted 20 years, new one's can last another 20 or more given the car's future use.

I've got a new pair of Gert's RSR's to go on too, looking forward to that stage of the rebuild.

RSRs? They are worth every penny imo. Perfect mix of louder v too loud, and no boomyness. First time I started mine up after they'd been converted, it set the wife's Alfas alarm off. I put it down to pure jealousy on her cars part. Very Happy
