Muffler delete on A7

[bmre90]

So just did a Muffler delete on A7 (C7) it sounds good at cold start and normal drive around the town. However the drone is bad at 2k-2800 Rpm.
Is this usual? Wondering if Resonator delete will have the same impact?

center muffler?
stiraght or X-pipe?

just the Muffler next to exhaust tips.
No X pipe.

I dont how loud it will get if i go with X pipe now that i have deleted the Mufflers itself.

To be more clear, all i did is straight pipe AFTER the resonator and single exhaust tip.
Coming from BMW, this is a pretty famous mod on M series, so i decided to just delete the mufflers rather than resonator.

well you should have done the opposite !! delete the res not the mufflers ! that has to be loud

i guess i learned that hard way.
does anyone know if active noise cancellation is also based on the rear mufflers. i feel there is more noise in cabin after this :=(

God this sounds like a bad day! Just order the AWE setup and call it a day, or put the old stuff back on.
