4AGE Zorst rattle?
Hullo.
We've been trying to track down a rattle/buzz coming from our exhaust system. We have a 4AGE and the raw manifold, along with an MK stainless
silencer.
We did find a nut rattling around between the side panel and the interior trim, so this was extractified. Also, one of the downpipes going into the
collector was loose so a small blob of weld has been put on... but it still buzzes (at around 3000-4000 rpm).
Anyone else have similar? We are wondering if it is just a characteristic of the engine that at a certain rpm, pulses of exhaust gas cause a resonance
in the system. Its odd, because we used to have a home made silencer and exactly the same happened then!

The only time I get a rattle/buzz from the 4A-GE in my MR2 is when the exhaust hanger is touching the bodywork, apart from that, never. Is it a
metallic noise more than a blowing manifold gasket noise?

My 4AGE has always had a budgie chirping at about 3000rpm. I think it eminates from the alternator belt? The engine never really gets to rev that
low so I have yet to do anything about it.

My "Wunoff" silencer has a slight rattle at about 3000rpm, but apparently they all do. Something about the perforated tube working
slightly loose ?
The sound of the carbs soon drown it out so I don't worry about it
