Hi all,
I've watched loads of videos of people who have removed secondary cats and or resonators. To me, personally, a lot sound really raspy and un-refined, more like a shouting car rather than a deep rumbling puuurrrrr like the original C63 sound.
I just watched this video, I think, going from description, guy has just removed his primary cats and left the rest, sounds really nice, same noise, just deeper, I've asked him to confirm what he's done exactly but sounds good, see here:

Eurocharged says removing primary cat's give much better gains over removing secondary in comparison when I remap next month as they are pretty hefty, not too bothered about gains mind, just sound really. Who else has just removed primary but left everything else completely stock? If it sounds like the above I am doing it! Would be quite easy to unbolt under manifold, cut cats and install straight pipe as I have good fabricator, or gut the primary cats, bit messy but doable.
I had straight pipes on my SL55 from the primary cats onwards, sounded fun for about 2 days then I hated it, was completely insane
I'm getting older and want to retain the nice sound AMG built, just with a bit more ommpphhhhh
Cheers,
M
