Resonator delete BMW Z4 M40i

Resonator Delete BMW Z4 M40i w custom y pipe. I'm pretty happy with the results for $250!

It's a very nice mod. I'm so glad I deleted the resonator. It's not too loud, just right. It sounds amazing without being annoyingly loud all the time.

Dang that sound is rly good 👍🏻

Really nice ! I expect to do the same on mine with EU specs. Does the sound becomes a bit louder compare to stock or only the tone is modified ?? Thanks

[@highsiderider]

@thomascalinaud2532 thanks 😊, it does become a bit louder, but not much. It's a nice deep tone and louder burbles

It's resonator delete but with also Downpipe. Original cannot be loud like this with only resonator out.

[@highsiderider]

@Chaletjohan-wo4ke t I appreciate your input. I'm keeping the Downpipe. It would be too loud for my liking. My son has the M240i stage 2 with Downpipe free flow and resonator delete. It sound louder with a much more hollow sound.

[@Chaletjohan-wo4ke]

​@@highsideriderreally suprised tchat the Downpipe is still there. But it's sound perfect i have to say. I have M40I X3 2018 and i try to find something for get nice sound from this amazing 6 cylinder.

​@Chaletjohan-wo4ke Thanks, yes, this b58 sounds amazing.

Have you noticed any drone at freeway speeds or cruising? I want to do this but don’t want it to be annoying in the cabin

[@highsiderider]

@ShattuckEsteban no droning, just sweet deep sound. Plus, you can switch to Eco or Comfort mode if you want quiet. Really, it's not that loud.
