Active Valve Performance Exhaust

[markleigh]

Looks like good option...
I leave house at 6.15am with Roush axle back.
...Am known as the 'street's alarm clock' (well, that's the polite name they give me)

If we get it or the option to pick it. With resonator delete will be loud and lovely and headers then wow, in theory should remove the need for after market exhaust.

In quiet its 72db, I think current stock exhaust is like 76db and in sport mode the active is 82db so quite a bit louder and from the videos I heard it was louder for sure. Resonator delete should push that to 85db+ and headers louder again which is getting pretty loud.

You're a writer; what are you doing leaving the house, or being up at 06.15?

Writing doesn't pay the bills - so I have a 9-5 too... except in my case it's a "leave at 6.15 for the 9 -5..."

This is madness. If you were waking me up at 6.15 every day I'd auto center punch a window and chuck in firelighters.

Maybe my neighbours will club together and buy me an '18 with the exhaust valve... I'll start the crowdfunding page now.

Outrageous; I shall buy more of your books. Probably.

Does anyone know how this compares to our current stock exhaust and one with a Roush Axle back on?? I.E. will the active in Sport mode be louder or quieter than my 2017 with stock except Roush axle back??

That's odd numbers, my MF competition (ON my eb) registers 109.4db.

That's a lot, but too many variables. Measured with what, at what distance, what angle and how many revs?

Some bloke with one of those measuring devices and a wooden triangle. to make sure the angle was right :lol:. Think it was like 4-6k or something

Wansn't mine TBF, but same same exhaust/engine at BH.
