If I Add Borla Midpipes,[no Second Cats ] To An Axle Back Bastuck System, Will It Drone On An Auto E90? Anybody Have The 2nd Cat Deleat Pipes And Bastuck With Any Experiences?thanks

Mine droned a lot with catless dps. Borla are crappy pipes, dont get them. Huge flow restriction at the connection with the dps.

i have stock downpipes, what mids do you recommend?

You are better off getting catless dps or just saw off the cats in the oem midpipes and replace with resonators.

I have cpe midpipes and when I went catless it drone and rasp like a bitch until I welded some resonators into the CPE midpipes and the rasp was totally eliminated and the drone was subsided greatly!

i have RR mid pipes and a bastuck muffler, notice some drone but nothing too intrusive. if you get DPs just get some resonators

+1 but for those that the drone bothers them now even without DPs, get the resonators installed in the midpipes and you will be happy because you will have tuned your exhaust note to the point that it will make you
