800 is fine m8 my evo 7 engine ticks over @ that

But the sound coming from the exhaust was a bit intermittent,unlike before the exhaust was continuously sounding good all trough out but now even when full stop or when your on traffic lights on cue the sound was a bit just jumpy (inconsistent)

this is what mine sounds like on tick over, some times she does sound abit lumpy if that's what u mean?

That's exactly what happened..so how you manage
To sort it out

Potentially due to temperature change causing different afr or you have the start of an exhaust leak
