Exhaust Cutouts....
What has anyone do so far?
Are you putting them before or after the secondary cat?
Also are you removing the resonator as well? (I think c63 has them..)
Where did you purchase your cut outs?
Anything else needed?

hey there. a lot of info is available in the FAQ at the top of the topic list and also using the search tool. but I can give you a quick run down:
the consensus seems to be to cut out the secondaries and leave the resonator to get a more aggressive exhaust without changing the overall tone. you can remove the resonator as well if you want a brighter sound, otherwise leave it for more of a rumble. there are a lot of options for pipe replacements depending on what direction you chose to go, its easy enough to just have your shop source some 3'' pipe but you can search on the forum for products as well
good luck and enjoy the car

oh i see. i've never heard of that on a c63 before. but from google I found this video which shows them done behind the resonator, everything else seems intact down there

I have em on mine...it's loud, but not as loud as say a new 'maro/vette with cutouts...I even deleted my resonator (thinking of putting it back and just deleting my 2ndary cats)
