Repairable?
aka_shortie - 22/8/11 at 01:30 PM

Guys, im after some suggestions on the best way to repair this exhaust pipe that has snapped off just before the rear box. Normally i would just replace the whole exhaust but it is on Mrs shortie's car which is currently up for sale and in light that the value of the vehicle is pretty low, spending £200 etc on an exhaust that we wont get back on the sale is a bit annoying.

So, is it repairable (temp fix)? And if it is, whats the best way to do it?








Thanks for any suggestions.

Thats shagged you won't make a safe repair that will last more than two minutes.

got a welder?

I cut back the bits that are knakered to good pipe and clean up the box end and weld in a new short straight section.

having done the tin can version, which lasted as long as the rest of the car, I would still recommend a welded section for peace of mind and, easier to sell if the prospective buyer looks underneath,....

I think it is possible to repair with a welder and some patience. MAYBE it will be possible to buy a pipe reducer which will slide into the cat/silencer a cm or 2 and then sleeve over the old pipe section. Weld around the reducer and that will probably last a good couple of years again depending on the abuse it gets....

EDIT: Not in the UK but gives you the idea: linky

fibre glass will sort that...! it will smoke for the first heat cycle, but then it will settle down and be absolutely fine for ages... Just support the backbox, and then wrap the wetted out fibreglass around the joint, and smooth it down to ensure a seal.

I wouldn't have thought there's enough there to use any sort of jubilee clip-on repair thingy. I've welded something exactly like that before by cutting some little bits of strip to 'bridge' the crap edge and welding them on - say little 5-10mm bits cut off some 30mm strip, enough to go all round the pipe.

Gets my vote but use woven tape as it's a lot easier to wrap around the joint as doesn't fall apart like chopped strand will..

How about a tight fitting tube inside to take the strain, and then the above methods to seal it......

Plenty of metal on the box to weld to so you should be able to sleeve it back to the pipe. Get down to the exhaust centre skip and find slightly larger pipe and slot it then use fire gum and a clamp.

Cheers for the advice guys.

Are we serious about using fiber glass or am i being blagged? Will it withstand the heat etc?

£200, is it a ferrari?

Last few times ive bought back boxes/midsections theyve been about £15-35

100% serious.... It will be just fine. How many people have fibreglass bodywork very very close to a red hot exhasut header with no problem? This is much further back, so much cooler, and will be just fine.

Agree with Triton though, that woven tapes are a lot easier to wrap as they dont fall apart like CSM.
