edwardatherton Posted May 8, 2007 Share Posted May 8, 2007 Is there any reason why I couldn't use a piece of flexi exhaust as a permanent section? It isn't for the S1, it is actually for my wife's Fiat 500 - those tiny engine practically shake themselves to bits, so I thought using flexi exhaust may reduce some of the vibrations carried through the system...

Tonk Posted May 8, 2007 Share Posted May 8, 2007 IIRC the exhaust on those are only mounted to the engine and not to the body or the car anyway, so i cant see much point Quote Link to comment Share on other sites More sharing options...
edwardatherton Posted May 8, 2007 Author Share Posted May 8, 2007 IIRC the exhaust on those are only mounted to the engine and not to the body or the car anyway, so i cant see much point Yes they are, but some of the exhausts are really badly made and when you do up the bolts it puts a lot of strain on the exhaust elbows - this has led to a few stripped threads in the alloy head before. I've tried 'persuading' it to fit better without much success! Talking to a friend earlier, he said that his wartime Jeep has a flexi section below the manifold, so why not do that on the Fiat...?

Tonk Posted May 8, 2007 Share Posted May 8, 2007 there used to ba an autoitalia place in ringwood that done performance parts for 500's 126's etc, bout 70 quid for the system, fitted very well, that was a long time ago though. to answer your question, i guess if the box part is properly mounted to take its weight then flexi could be used, i dont know about balancing the back pressure on the pots though. i guess it wouldn't make much difference. usual disclaimer applies Quote Link to comment Share on other sites More sharing options...

Mo Murphy Posted May 8, 2007 Share Posted May 8, 2007 Flexible exhaust tends to break up in my experience. better to have the exhaust modded to put less strain on the manifold if you can. Mo Quote Link to comment Share on other sites More sharing options...
Steve King Posted May 8, 2007 Share Posted May 8, 2007 Flexible exhaust tends to break up in my experience. better to have the exhaust modded to put less strain on the manifold if you can.Mo I agree and furthermore it gets less flexible the older it gets. In some cases it just seems to sieze solid. Steve Quote Link to comment Share on other sites More sharing options...
Les Henson Posted May 8, 2007 Share Posted May 8, 2007 A flexible exhaust section in the wrong place can cause more vibration where it's not good. It sometimes puts extra strain on the exhaust mountings either side of it and they crack through metal fatique. Les. Quote Link to comment Share on other sites More sharing options...

landmannnn Posted May 9, 2007 Share Posted May 9, 2007 British leyland used to use flexi sections on such design classics as the princess and maxi. I suppose they couldn't be bothered to engineer the vehicles properly to stop the engines moving too much. A bit of a bodge really and not very reliable.

edwardatherton Posted May 16, 2007 Author Share Posted May 16, 2007 We ended up using spacers to mount the exhaust so that it fitted properly. After an engine change, new carpet, new exhaust, recon alternator and new fuel pump it passed the MOT today! I get an extra half an hour in bed now that I don't have to take her to the bus stop every morning!!! Quote Link to comment Share on other sites More sharing options...
