435i have MPE and wants to delete the resonator do you recommend it? What the difference will be? |
It does help the MPE and I'd recommend it overall. It will make cold starts louder and you might not want to do it if you have an aftermarket downpipe. Resonator delete maybe increases volume 15-20%. I ended up selling my MPE and upgrading to AWE.
