I'm a little surprised no1 responded to this yet. Have you installed it yet? I have been looking for a high flow cat option, but the best I can find is a company in Italy for $1,800 which is insane. I was also considering going catless, but I don't want to be "too" loud. its fairly noisy with the MF corsa exhaust. I don't know how much more a catless downpipe would add as I've never explored this option before
. Let us know how it goes please!
