I removed the main muffler on my '10 SC and it sounded like a volley of cannon fire on the downshift, even at the lowest revs. It's very different to the effect on the previous model, and frankly is just not an option. It sounds like there's no exhaust at all.
I put that one back on and took out the smaller one and bizarrely the sound became thin and tinny.
I'm really disappointed, i loved the exhaust note on my '06 with the rsonator removed. This time it's looking like I need an aftermarket exhaust.
Fortunately the sound of the stock '10 SC is a touch lower than the stock '06 SC. Quite deep at speed, but much too anaemic at tickover and when accelerating. In fact, it rattles at tickover, and there are all sorts of wheezes, buzzes and twangs as you go up the rev range from rest.
