My system is stock, just with the resonator removed and an x-pipe put in its place. If I got you right that's what you are considering?
From the inside there's very little difference from stock, just a little more growly at low rpms. From the outside it sounds deep and growly at low rpm / light throttle, and very nice and crackly as the revs rise and throttle % increases. And it's not too loud at all. (As you can probably tell, I love it, and wouldn't change my exhaust any further at all!

).
I'll make a short clip this afternoon of what it sounds like from the outside
Once I've made the clip though, I have no idea how to post it on here.

Last (and only) video I posted I had to email it to Gustav who put it up on my behalf. Anyone know how I can do this without bothering him again?
