Can't Reliably Pass 105dB Static - Options?

Paul, I have some 3" track cans that I don't really need any more, mine now normally reads about 98db.
As you live about 15 miles from me if they fit your car I am happy to share them.
Thanks Martin, that's very generous, unfortunately I've just measured the tailpipes and found that they are 3 1/2" OD.As you live about 15 miles from me if they fit your car I am happy to share them.
How about a couple of these shoved up my tailpipes?

For anyone else in a similar position, another option is Silverstone. I didn't realise that there was no static noise test until going a couple of weeks ago. Sadly didn't get to drive as I was on the reserve list, but plenty of PAX laps, and several cars were significantly loader than mine.

Cheers, I'm seriously considering getting a track-day in at Silverstone this year, so will hopefully get by with inserts rather than the power-sapping ACT cans.
Those track day cans strangle the engine above about 5k.Interestingly when I was at Snetterton last month the MSV guys asked me what the red line was, I said it's the V8 so about 6k, expecting the usual 4.5k noise test. They decided to look it up on their list and then asked me to hold 5.4k!! By some miracle it passed at precisely 105dB without the inserts.

Spa is also 103dB drive by and 107dB static. drive by is measured from the F1 pit complex.
Thank you.My experience of the Spa static test has been quite varied: sometimes there has simply a visual inspection and your car and it passed if it wasn't radically modified, on other occasions there was a physical static test at the declared 3/4 rev limit.

I ran the ACT track cans for many years, sap a little power from the very top end but only at the sort of revs that are just not worth using as you are way past peak torque by then, they also improved mid range torque quite a bit so net neutral I would say.gruffalo said:
