I have previously owned a set of Remus Hexacones which were lovely but were too loud for some UK tracks even with baffles in (and when they flew out the back onto the track after shearing off ) had to get the round akras instead, I know different factors change the reading (age of exhausts, time of day, need a new exhaust seal etc) but it would be nice to get an average of readings of exhausts you own get at trackdays.

I would certainly be interested in FMF's as I would love a set of them but expensive purchase if they dont meet noise requirement.

Do you guys outside UK get noise tested?

So I will start

Remus Carbon Hexacones 105-107db with out baffles 104 with baffles

Akra Round 98 with baffles

SO Mivvs? Full akra system? HP corse? Terminogis? FMF's?

Leovince are well below 101dBA at 6000rpm in neutral with baffles in at 1 meter distance.

My Akra Evo's come in at between 98 and 102 without baffles. 98db last week at Oulton

Static sound (neutral) isn't the biggest problem here, it's the dynamic measurements from meters on poles around the track that are a bitch, they get you black flagged...

My Mivv's I had were 104 DB in and I think 115? With them out at cadwell then 108 DB in at Snetterton. I've now got akro's EVO'S but not had them tested.
