Just installed an "S" muffler on a '13 V8V...

Man what a difference. This is an equal comparison as I have had fuse 15/22 pulled on both mufflers: The idle is somewhat louder but above 2000 or so rpm I would say it is 60% louder than the standard muffler. Also there is a nice burble on overruns that was not present before. I bought it used on Ebay and polished it to a mirror finish so it looks a lot better than the standard also (altho I could have polished it as well). I did not want it too loud (My Gallardo with an aftermarket exhaust is LOUD and I wanted this car a little more tame) which I was afraid the aftermarket exhausts would do so this is exactly the level I was looking for. It has really increased my driving pleasure and it was already very good before. I can highly recommend it to anyone that wants more sound but not too much.

did you weigh standard and S muffler to see how much lighter the S muffler is?

Did not weigh either but the S definitely felt lighter and looked a little smaller than the standard one.
