County Needs New Exhaust
1987 110's exhaust has about had it. For the past few years I've tried different things (patching, splicing with flex, etc.) but it never seems to last and on a 300km trip today the wife's feet started getting very hot, then of course with the window down I could hear a bit more of the turbo whine than normal, so I knew I'd cracked it again. Seems the old pipe suffers from metal fatigue. Not even rough riding today, 90% on pavement with some gravel hardpack, so it's time I fix it more permanently.
I'm thinking time to replace the exhaust with new. What option(s) has anyone tried short of building some custom exhaust?
Ideally I'd like it to stand up better to the 4bd1 rattle/turbo heat, not crack for at least a few years at a go and perhaps give it a bit more clearance from the tyre on tight radius turn (rerouted it slightly a few years ago when patching to help this with a bit more clearance in the event of a tight turn and jolting maneuver in concert). Am also considering some shielding between the pipe and the pan so SWMBO's toes don't light on fire in summertime on long drives.
Have thought about expanding the diameter by perhaps 30% or so as well (to maybe 3"), as I believe that will help with diesels in general, perhaps with a snorkel with better air intake as well (tbd).
Has anyone done similar work? What have you done, tried, modified? What works and what doesn't/didn't? I've seen some who have suggested getting the military perentie replacement exhaust and fitting/modifying that as a starting point, but not sure. Input and guidance appreciated. Thank you in advance.
Scratching my teenage itch now that I'm in my midlife crisis...
