2015 BMW 535i xdrive exhaust questions
I have stock down pipes, stock air intake and filter.
Upgraded charge pipe, next upgrade will likely be intercooler > stage 1 tune MHD.
I’ve replaced the stock mufflers with valvetronics universal valved mufflers.
I’m getting quite a bit drone around 1.5-2.5k rpm’s
Im new to this, so I’m not sure what’s causing the drone sound. I know that the resonator is a huge piece. But I left that alone.
I’m okay with the exhaust being louder if it means less drone.
I’m also curious if it’s possible to keep the same sound now but with less drone/no drone.
Curious to learn more while also about my specific situation is possible and where I’d begin to start.
Picture of stock mufflers to see, replace mufflers either the valved ones.
