Z4M vs E46 M3 Decat

Well done. Brilliant thread!

I'm not a fan of the "classic" e46 M3 rasp. But great work nonetheless! With aftermarket parts being pretty expensive and not readily available in the used market for the Z it's modifications like these that are so awesome to see!

I knew this was possible, but had no idea they would be different in length, I always assumed it was only the clocking. I am interested in the mufflers you posted, I have OE X-Pipe, Remus, and DKF 300cells cats and my car is too loud, to the point I have been thinking about putting my OE US Secondary cats, primaries are gone as I have EU headers.

So maybe the design of the OE S pipe helps with muffling sound. everyone says Remus is quite, well, that most be deafened people LOL, is VERY loud, at least in my setup.

That sounds quite well balanced in the second vid. The intake is still present but with a nice bit of backup from the exhaust. I appreciate though, that online vids never get it quite true to life.
