R55 Resonator AND cat delete anyone ???

Removing the catalyst will only increase that since the honeycomb inside the cat will reduce exhaust notes and tone.
Read up on some of the archived threads in the R56 section about such.

Hey guys! I just got back from the Muffler shop, they did a secondary cat and Resonator delete on mine.
and let me say, it is amazing! Close to NO drone at all! love it. it has a nice deep rumble when it needs to be =]
no burbling or popping noise (although i was hoping to have some)
Will upload a video by either today or within this weekend!

doesnt the midpipe already removed the secondary cat and resonator? if u're talking about the cat that is right next to the turbo, then yes it wud throw a code since there is a O2 Sensor in that cat.

i replaced the stock exhaust on my 2012 cms all4 with a milltek downpipe-back system
it is straight 63.5 mm pipe from the downpipe to a muffler located at the rear of the car where the stock muffler was
no resonator, no second cat, no drone
no CELs
the tone is much lower/deeper
quiet enough at steady speed, but "talks" nicely with the throttle open

I have no 2nd cat, no muffler, no resonators on my Clubbie Justa with Dual exhaust. I put the stock resonators back on and it honestly did not change the sound in the slightest so they came back off. It sounds pretty good for the money. There is a spec of drone while cruising above 50. Nothing close to unbearable. I would definitely recommend it.
