Sounds great. Nice rumble at idle and not too loud while driving. Will definitely keep buying auto anything and flowmaster products

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.
