Now I've changed to a 3" which was recently tested at Brands in static at 89db.......am I right in saying it should be fine on drive by aswell
Like I said. I was 96db static and hit 95db drive by. But the weather and wind direction plays a massive part.
I also heard from my recent track day that MSV tracks have got more strict on noise in the last few months. At Snetterton their sound meters on track side now take photos of the car when it's triggered and this could be same for many tracks now.
I'd still buy an exhaust baffle for back up. Last thing you want is to get black flagged early on and it's a day wasted.
