I was originally running a catted 3 inch TBE and found it wasn't loud enough.

I've now upgraded to cat-less everything including 3ich TBE, it is a noticeable difference but not a whole heap. Obviously gains on a dyno graph will show you the real difference.

On idle it's not overly loud I was very surprised as it was a very subtle note! But on WOT that's a whole different story.. It's insanely loud even at 3 grand!

As for yellow canarys I haven't been pulled over as of yet with the cat-less system.. Been followed a few times but nothing out of the ordinary.

I would recommend going cat-less IMO as I prefer the little extra gain and a very loud and in your face exhaust
But none the less comes down to personal preference and what your aiming for.

Hope this helped!
