    Quieter than stock Exhaust system needed. 08 Denali xl

    I agree that my Denali has a very nice rumbling sound at startup, especially when im standing behind it and i use the remote start feature. However, i take some long trips with it and that constant droning noise it makes at a highway speeds becomes veryyy annoying..

    AFE Dry filter for 08 Denali xl (louder than stock filter?)

    Yes i will be just replacing the stock filter element. I have heard some people claim they hear more of a "sucking" sound by just replacing the stock filter? If I got 1 mpg more, I think it would be worth the extra cost. thanks

    AFE Dry filter for 08 Denali xl (louder than stock filter?)

    For anyone that has the AFE dry syn filter. Is it any louder than your stock air filter? Do you notice any MPG gains at all? Thanks!

    Quieter than stock Exhaust system needed. 08 Denali xl

    I actually didn't know that the LTZ had a smaller motor. They seem to get the same gas mileage, mine always reads around 14.6 as does the LTZ. Yes I have driven escalades many times. The escalade is def louder than the LTZ, but I think it's slightly quieter than the denali..

    Quieter than stock Exhaust system needed. 08 Denali xl

    Its def night and day. Also the droning is terrible on the stock denali exhaust. While i was cruising at 60 mph in the LTZ, the exhaust is 100% silent in comparison to the denali. I personally don't even know why gmc made it sound that way, it's an suv not a sportscar. lol

    In need of a quieter exhaust. (08 Denali xl)

    I have a 2008 yukon denali xl, and I find the stock exhaust to be too loud for my liking. Is there anyway I can put an exhaust on it similiar to that which is on a late model Suburban ltz? They are practically silent in comparison to my denali's stock exhaust system. Thanks in advance!

    Quieter than stock Exhaust system needed. 08 Denali xl

    I have an 08 denali XL, and i think the stock exhaust system is a bit too loud for my liking. I recently drove a 09 Suburban LTZ, and I really liked the way it was practically silent compared to my Denali.. Is there anything I can do to make mine as quiet as a stock Suburban? Thanks in advance!
