C63 muffler installation
Watsup guys so I am purchasing some shorty headers for my e55k and I also have some c63 mufflers coming my way. I was wondering what way should I have me installed so I have the great sound but no drone. I know a smog shop so that's not a problem, also I have ready that sometimes a CEL or some type of odor occurs, I also do not want any of these to happen. Should I go headers, mufflers and straight pipe, or headers, mufflers X pipe for resomator and primaries etc thanks

Headers, X-pipe, mufflers would be where I'd start. If it's too loud you can always add a resonator, or put your stock mufflers back on (you are going to get a lot more noise/power by removing the primary cats via header addition so perhaps add the headers and X pipe first and see if you need the C63 megaphones).
You'll need a tune to avoid CEL and get the most power.
