Varsas Posted February 4, 2013 Share Posted February 4, 2013 Hi all. Long story short I need to fit a new exhaust to my 2.25 petrol 1972 SWB land rover and am struggling. I have removed the old one, which was subsequently removed from my garden, so I don't have it anymore. I ordered a complete new exhaust from a respected specialist (not sure I can name names here?) but I cannot get the downpipe to fit. I tried everything, but it would not clear the gearbox sump. After giving up I took it to a friends, he manages an exhaust/tyre/MOT place. Up on ramps the exhaust still would not go on, so we unbolted the gearbox, jacked it clear of it's mountings and tried again. This time the exhaust would slot under the first crossmember and above the gearbox mount like I believe it should however you cannot bolt up the downpipe to the manifold as the downpipe hits the bottom of the gearbox (this is with the gerabox jacked up) and even if you could the downpipe ends somewhere near the middle of the car, a good foot or more away from where it needs to be to line up with the centre pipe. So another down-pipe was ordered form a different supplier however it looks exactly the same as the one I had (despite being from a different manufacturer) actually, that's not true there are subtle differences but when compared side-by-side they look very similar indeed. My friend believes it will not fit. Before I waste any more of his time is there any reason I am struggling? My landie does appear to have a military chassis (ammo box welded underneath, heavy duty springs, extra fuel tank under the passenger seat) could that cause me problems? What if I have a petrol engine on a diesel chassis, something like that? Does anyone know where I can get a quality downpipe from, just in case it's just poor manufacture? Anyone got a good picture of what the down-pipe should look like and/or it's routing through the car? It might be that it turns out the new downpipie fits fine but thought someone else might have been through this. I fitted a new exhaust to my diesel land rover and had no problems at all. Thanks for any help. Quote Link to comment Share on other sites More sharing options...
secondjeremy Posted February 4, 2013 Share Posted February 4, 2013 Petrol and diesel use the same chassis. Britpart exhausts are excellent (and very good value from some suppliers) I'm not aware of any poor fitting exhausts out there. Diesel front pipe is slightly longer than petrol on bit nearest manifold. Its 2 or 3 inches - as the petrol manifold stretches further down. Apart from that S3 exhausts are the same for petrol and diesel. S2 and 2a diesel are different and come out sideways through the wing - and fit S1's as well. Front and intermediate pipes are different - silencer is the same. Front pipe can be a problem - needs vehicle raising to get it in Quote Link to comment Share on other sites More sharing options...
Varsas Posted February 5, 2013 Author Share Posted February 5, 2013 Thanks for the reply. The car has a new manifold on it, which fitted the old exhaust so I assume that it's correct. Sadly the downpipe which definitely doesn't fit is a britpart one. Just wanted to check it wasn't something silly. Hopefully my friend will call me later with good news...

Varsas Posted February 5, 2013 Author Share Posted February 5, 2013 All sorted now, he managed to get the britpart one to work and, as above, it fits very well indeed. Just down to technique I guess... Quote Link to comment Share on other sites More sharing options...
