Do you have any issues with a nasty howling sound during WOT? I have this same set up on my M Sport 135i, I had the resonator deleted and my god the sound is SO much better but I have this damn Howl sound, only been installed for about 2 weeks. Aside from that all is well, many people underestimate this exhaust but it has such a nice deep elegant tone. The resonator delete was like 200 bucks and now I have the same sound ALL the way through any RPM. I will try and post a video tomorrow from inside and out. My camera picks up the sound exactly how it sounds in person. Enjoy your exhaust!
