Title: Cobra exhaust
Post by: smarty72 on October 12, 2018, 07:03
Does anyone know how loud (In Db's - not very or annoyingly!) a Cobra exhaust is?

Looking to book a track day for the 22nd, but wanted to check there wouldn't be an issue with the Cobra...

They're loud IMHO especially with things like de cat manifold and induction kit however I doubt they're loud enough to cause an issue.
Not sure I have ever seen any reference to just how loud they are in dB.

Saw someone with a Cobra get on at Castle Combe which is 100DB limit

I've got an app on my phone that measures decibels, I use it for work, it's probably not 100% accurate but imagine it would be good enough for what you need.

The posted limit for the track is 105db, so hopefully be ok - standard induction too...

I just remembered that I downloaded one of those apps ages ago but never tried it -  no idea whether they're accurate or not...

I use Decibel x as it was free, it tracks near enough the same as the actual testing unit we use to measure the levels in the workplace. Certainly to 110 db, I've never used it above that as there's no need for it.

Ok - will give to a try tomorrow.

Car is tucked away in the garage with the battery off at the moment...
