Right then, no matter what is done, this bloody thing still won't quieten down, have taken off the downpipe and cleaned the manifold end, replaced the o-ring. Still no difference. It still blows, not quite as bad as it did before. Only underload. Inspected the rest of the exhaust and that's solid.
I'm guessing the springs could have lost their compression, so won't hold the joint properly.
So, wanna get rid of the joint itself and get one of these fitted...
This is obviously a motorsport product, but my V6 has a similar joint on it's downpipes.
I guess this is possible, anyone done it? Would have to keep that bracket there.
