ACT exhaust ok for 101db on trackday?
Discussion
Hi All,
It's been a while since I did a trackday but have just booked myself on Opentrack's Thursday evening session at Bedford this week. Can't remember what I hit on the noise meter last time.
101dB is the static test limit - do you reckon I should be ok? T350 3.6 stock speed6 with ACT carbon airbox and ACT big bore exhaust (cats still in place).

Well quick update after a fantastic evening despite the rain...
Sailed through the noise test. They asked me to do 4k revs and gave a reading of 96dB. For reference that was a nicely warmed up 3.6 engine with ACT big bore, ACT carbon airbox and cats still in place.
Had no problems with the on track noise meters either. I can confirm that they do operate a strict policy of ending your day early if you breach the on track meters. I think there may have been a Scooby black flagged, not sure if that was for noise.
Well organised day all in all and good mix of people. Free insttuction and pictures too all for £80! Opentrack would definitely use again.

Sadly I've sold the T350 now but I'd highly rate the ACT system. With cats in it's a much nicer sound and less "boomy" at motorway speeds. Provides a few pops and bangs on the overrun but still understated. If you take the cats out or had more free flowing I suspect you'd have a lot more pops and bangs. Not an expert but I'm sure Jason (STR8SIX) once warn me away from some of the sport cats on the grounds that they don't last very long. Worth doing your research before shelling out £££
