I've been searching the internet to find out how to improve my Mo'. I was thrilled to find out that this Flowmaster muffler would fit my Murano because for less than $100 I could get my Mo' to sound harsh, with a noticeable growl when starting and accelerating. One thing I would recommend is removing the resonator to get maximum growl. At first I just went with a muffler replacement, it sounded good but the mechanic at the muffler shop suggested removing the resonator so I went back a day later to have the resonator removed and it made a world of difference. I'll try to post a video of how it sounds, there are some great examples on youtube if you type Nissan Murano Flowmaster. Hope that helps.
