Thanks. Not sure about MPGs yet. It may have slightly increased, but I need to go through a few tanks of gas before I am willing to make any claims. I am still on the stock tune for now.

I got mine through Autoanything. Give them a call and they might be able to apply a small discount for you, but Corsa doesn't let them apply their typical 10% off coupons to their products.

I just installed the Volant CAI system with the Donaldson filter. I had this installed for a week before installing the Corsa exhaust, and I will say, it sounded good, but might be a little much without the added exhaust sound. Overall I am pretty pleased. As others have stated with the Volant system, the fit and finish could be a little better (the cover doesn't directly line up with the box). The only thing I was really disappointed with was the cheap rubber hose that comes with the system for the valve cover breather lines. The hose would easily kink, so I went to the local auto parts store and bought 3 feet of corded thick rubber hose that will not kink for $7. I do really like the Donaldson filter and I think the system sounds great when combined with the Corsa exhaust! I don't know if it is providing any "colder" air, but there is definitely more air available vs the stock system, so that can't be a bad thing...

I just installed the Corsa Sport exhaust today. Single side exit, black tips. Really love it so far! Sounds great in V8 mode. You can hear it in V4 mode (helicopter sound...), but it isn't too bad. With the radio up and a/c on, I don't notice a sound difference while cruising on the highway.

Installed the Volant CAI with Donaldson filter and Corsa Sport Performance exhaust today!

I paid $630 to have it done (unsure of the parts/labor breakdown though). Mine was more expensive though because I have the color matched bumper and grill. If you have a chrome grill/bumper it would require much less film and time since they don't put the film on the chrome (I asked just out of curiosity and he said that the film doesn't adhere to chrome very well).

Got the 3M Scotchgard Paint Protection Film installed on the front end today. Very happy with how it turned out.

Installed my Fold-A-Cover G4 Elite cover and weathertechs today! Also touched up some rock chips on the front end with some Dr. ColorChip in preparation for a clear bra to be installed.

Here is my 2014 Sierra AT. Love the truck so far, almost 3000 miles.
