M235i with m performance muffler + straight pipes?

JaF22MPower · 11-14-2014, 12:32 PM

Hi everyone,

I've searched for this but haven't come along with anyone with this particular exhaust configuration. Has anyone heard or have a video of a M235i with MPE (or other axleback muffler) and then everything straight piped up until the downpipe (so resonator and sec cat delete). I know the popular configuration is down pipe plus exhaust, which sounds fantastic, but I don't plan on tuning so downpipe is out of the question. Thanks!

There is no second cat. I don't even think there is another resonator upstream of the muffler but I might be wrong on that.

There is a small resonator from the pictures I've seen.

Ahh ok. With that being said, would there be much sound to gain with removing that resonator (if it is relatively small)?

i did a resonator delete to stock exhaust but i do have a cattless down pipe. I did the resonator delete after i had been carless for a while and i did actually notice a difference even though it is a pretty small resonator

Did you have any sound clips of how your car sounds?
