Too quiet with just the muffler . Had to cut out the resonator. Sounds pretty throaty now probably perfect for a lot of people .

After tons of research on forums, auto aftermarket sites, and even calling the manufacture directly; I finally decided on the mild tone muffler (I couldn't find any reviews on this model). I have to say I am very satisfied with my decision. The sound is noticeable but not overbearing at all. Nice deep tone. Love the straight through design. I feel that it improved performance with a 3" cat back. Highly recommend.
