X3 - Resonator By-pass

alpwhite46 · 04-19-2017, 05:10 PM

Hi Guys,

Has anyone done a resonator by-pass / delete mod on the X3?
I haven't seen any videos but i have seen tons of people do it on the F30, E90's etc.

Have not touched the resonator but done catless downpipe and supersprint muffler. Sounds better but drones at about 1500 rpm. Its noticeable but not unbearable.

Left the two resonators alone, they're straight through anyway and replaced muffler with smaller, straight thru MagnaFlow muffler. Custom work at great custom muffler shop. Sounds great and out the door around $450 with all custom pipe bending and installation. Looks like a factory job.

Got a photo of that?
So if i did the resonators, you don't think there would be a difference (resonator delete that is)?
