A flex piece in the exhaust reduces harshness, i found that when i added a very heavy home made muffler on my home built exhaust an engine harshness at close to 100km/h (whatever revs that is in 5th) was reduced significantly too, I'm guessing it acted as a mass damper as well ?
Aside from the steering draglink there are no sub assemblies on a series LR that can't be or aren't already resiliently mounted to the chassis.It's the little detail items I mentioned earlier that appear to be the area where Rover didn't apply any effort. I found a Disco Mass Damper on the road in town a while back! That'd be a nasty lump of metal to hit some pedestrian in the shins when it fell off.They are little more than a shotput disc bolted to a V8 engine mount. The secret is to work out the best location to mount it.
Wagoo.
