    Moderate Rumble

    So far, so good! I was initially concerned about the db level that I would hear in the truck. The rpm range is limited for optimal rumble range for my Titan to be around 1500-2500. That is just what I was hoping for from my research. I really have not noticed any fuel rating increase as of yet. However, that is hard to judge due to the fact that I tend to stay in the rumble range when applicable.

    70 Series Sounds awesome on 5.0L F-150!!

    Love the low rumble my truck makes now!! I did Not install this myself, Took it to a muffler shop had them do it. I also did Not take out the exhaust resonator on my super crew cab truck, And it sounds fine to me. I get alot of comments about tone of my truck! Very happy customer!!

    Very nice

    Really like it. Not too noisy that you cant talk but can really hear more of a deepness to her. It opened her up more on top of the k&n cai i have on it. Really like it and would reccomend it.

    Sounds great!!!!! 40 series

    Muffler sounds great when added with a k&n 77 air intake. Just remember new sierras and silverados, need to have the exhaust adaptive valve locked in full open position for full effect. Spring loaded valve damper inside pipe 6 inches after factory muffler. There to keep down sound when in v4. Does not effect performance of vehicle. Also remove the resonator. Worth the investment!!!!
