I've not measured it myself but I know of a car with the same set up that was recorded at 125 dbs. Not sure how they measured it though
With a dB meter. There is a vid of my car with one at the exhausts. I'd have to get it rigged up for drivebys for a laugh!
Car sounds ace Liam. Loving the flames, that does it for me!
I know they would use a db meter Just, I'm not sure actually how it was measured e.g a couple of inches away from the tail pipes, at what revs, drive by? full chat? etc etc
