Another V10 FSI carbon clean

Just having the work done to gut the manifold has certainly improved the intake sound. Much deeper and throatier from in the car with the windows open or closed under any level of acceleration.

Next job is imminent, which is a decoke of the engine and a dyno/remap to tell the car how it should now be running, as well as tweaking to turn off the engine light which has come on due to the flaps being removed from the manifold, but that was expected.

I agree, the induction sound is slightly richer after the flap delete. I have also wired the exhaust flaps open on my stock exhaust which really add to the overall sound package.

Pleased you found a source for the decoke, not long now until she’ll be back to tip-top performance!

I was crawling underneath the rear bumper to tie the flaps open the next morning after I bought the car

if there's one mod that S8 owners should be doing, it's this one. Had one pair of the centre silencers removed and replaced with straight pipe as well, which opens things up a bit more.

I can vouch for this mod, I had it done after seeing your report, what a difference it makes! Everyone says it's quite loud now, but I don't hear it in that luxurious cabin. It's great fun driving with the window down in places where I can hear it roar as it accelerates or that glorious cacophony of noise as blips and changes down under engine braking
