Should i remove 1 cat and the resonator?

a while ago i put in my car a new muffler but i didn touched the cat and resonator...

im thinking to remove 1 cat and the resonator... it will be insanely loud or mellow??

i really like the sound now but i want the exhaust to flow more freely ....

Youll notice a sound gain for sure when removing the resonator and the 2nd cat. Id say youll be better off waiting for the release of some headers that will eliminate the first CAT. DraXas is working on a set of headers that will only run around $350 so that might be a good option to wait for

(2thumbs) I took out the second cat and the resonator, the first cat is located right at the headers and has the ODBII sensor in it which you can't remove without the CEI light coming on, and installed a magna flow 22 inch magnapak (dance) resonator. Nice sound just loud enough. I didn't want to go crazy since most of my driving is highway. (dance)

The sensor should be easily relocated.
