Our '11 Suburbans average around 12.5 mpg. We do let ours idle a bit longer than the average Joe does.

My Duramax gets 16 in the city and on a nice stretch of flat highway I've gotten 23mpg, but normally on the trips up to ShowLow I get 21 mpg........ As for the suburban, it looks like it's going to be in the 13 mpg range for the city, but I'm thinking that a cold air kit and a programmer and I might get that up a little.........

Crawled under the car today to figure out exactly what type of exhaust system was installed.

From what I can tell there is 2 cats, X pipe and twin 2.5" Pypes M80 mufflers (Pypes mid muffler system)....from there it goes straight out the back to the 3" tips.

I really dig the sound of glass packs and that is exactly what the M80 is...and old school glass pack in a polished tube. It is pretty quiet at idle but when you get on it...well the sound is really unique...hard to describe. It also had the little bit of gurgle and pop on deceleration..which I know many of you are not fond of...but I love it...takes me back to when I was a kid.

I will try to get some video of it...but for now this guy has the same set up...
