exhaust pre-resonator removal??

templarklimek · 11-27-2013, 09:53 PM

Not sure if I'm wording this right but my Z4m had after the cats pre-resonator or something like that. I had them cut out and it sounded much better and a tad more power. No affect on emissions as it didn't affect the cats.

Does the M6 also have this type setup? I'm gonna look myself when I get it back next week but any input would be appreciated.

TY!

The M6 has 2 resonators on the center pipes. I removed them and it increased the sound level slightly on the bottom end.

PM me if you need more info
