Peaklander Posted February 2, 2020 Share Posted February 2, 2020 (edited) I’m almost there with my engine rebuild and when it came to refitting the down pipe I reached a familiar point. I have great difficulty in getting the exhaust to line up. I’m fairly sure that at some point the down pipe has been deliberately bent to accommodate an incorrect fitment of the middle pipe. I have sorted this with the correct hanger at the middle, some time ago and I managed to get things lined up some how last time If I allow the down pipe to bolt up to the manifold and find its correct position, it is pointing at an angle into the chassis rail at the other end. I have to really stress it to line it up. Does anyone happen to have a known good down pipe (no cat or flexible connector) off the vehicle and could you take a pic looking along it with the manifold end pointing upwards? Then I can compare with mine, although how I would straighten it I don’t know. Edit: added a pic but it isn't obvious!

Peaklander Posted February 2, 2020 Author Share Posted February 2, 2020 I think I'll cut a fillet out of one side and then bend it straight and weld back up. Hopefully that will work and it won't shorten by too much. Quote Link to comment Share on other sites More sharing options...
Stellaghost Posted February 2, 2020 Share Posted February 2, 2020 Hold it in a vice then heat section to be altered with a butane torch and bend back to shape do it in stages so not to kink pipe regards Stephen Quote Link to comment Share on other sites More sharing options...
Peaklander Posted February 2, 2020 Author Share Posted February 2, 2020 Hi Stephen, I did try that with my MAPP blow lamp but I either didn't heat it for long enough, or it simply won't heat it up enough. Does it work, doing it that way with so much metal? It would be good if it does. Quote Link to comment Share on other sites More sharing options...

Stellaghost Posted February 2, 2020 Share Posted February 2, 2020 Lots of heat maybe set up with a couple of fire bricks to reflect heat should go regards Stephen Quote Link to comment Share on other sites More sharing options...

Peaklander Posted February 3, 2020 Author Share Posted February 3, 2020 I got hold of some broken kiln pieces and managed to do it as you suggested @Stellaghost and just got it red enough to move @Bowie69. It wouldn’t move much but just enough. Thanks for the advice both. 2 Quote Link to comment Share on other sites More sharing options...
