Which is more effective at reducing the rasp, resonators or HFCs? The smell doesn't really bother so I'm open to either.
I think also a better rear section would help, but I don't want to invest too much into it. I would have bought a Megan exhaust if it fit the E93, but I'm not willing to remove the lower supper brace. Does anyone know of any similar options? I saw a M2 Performance exhaust on ebay that advertises fitment on the E93, but it looks to be very similar to the shape of the Megan exhaust and I have my doubts about it fitting. I'm considering the custom Magnaflow mufflers, but most of the youtube videos sound a bit "buzzy" if that makes any sense.
