It is louder then stock, but it's not as loud as most "straight through" exhausts. I believe the Banks Monster Exhaust is actually the "quietest" straight through exhaust on the market.
It did sound very good on my 10' 2dr. I got quite a number of compliments, even just when starting up my Wrangler.
As far as improvements go... I installed this exhaust and a cold air intake the day after I received my Wrangler. In a way I wish that I had driven it for a week or so to see how they improved the performance.. But then again, I didn't want to wait at all.
I will say that I had 4:10's in my 2010 Rubicon, so all in all I didn't get the best mpg, but I do think there was a little improvement. I enjoyed having it on while I had it.
Now on my JKU I spent a bunch a $ on the sound system, so I've been torn between my jeep sounding best from the outside, or the inside... Either way it doesn't make much difference, but I really don't want to go through the headache of trying to make this exhaust fit on my current jeep. It's made to easily go on a 2door 07-11 model.
Hope that answers your question without going waaaay to much info
