This muffler IS dual-outlet which means a stock 99 camaro like mine needs some pipework before this flowmaster can go in but once it was installed the sound was day and night; lots of people in my town have flowmasters but there is nothing quite like having one in your own car. I highly recommend this one if you have a car like mine and want a nice roar from your exhaust.

Installed on a Nissan Murano. Since the inlets and outlets are in the same relative position, it was a quick, inexpensive swap ($125 installation fee from a local muffler shop). The original muffler from the manufacturer made the engine sound empty and gutless. This muffler is much smaller than the OE trash can, so it better hides under the bumper. This muffler is more free-flowing with less sound dampening. This muffler mated with a strong V6 sounds great! It's nothing like a Civic trying to sound like a stock car. It's a more tuned sound rather than an unrestricted loud.

On startup, it growls to life. At idle, it has an audible but subtle gurgle. At normal acceleration, it has a nice, deep tone, but nothing loud or offensive. To catch eyes though, punch the throttle and it will bark!

Fyi, this muffler used to come stock on the V6 Camero. If you youtube "Murano Flowmaster" you can hear the results. For under a hundred bucks, this is a great upgrade.

UPDATE: I've had it for 3 years now and it's holding up well. There is rust on the welds but nothing has rusted through. I realize I should have coated the muffler with black, high-temperature paint to protect the welds from the harsh DC weather.

Great muffler for a great price. Shipping was really fast and very happy with the sound and look it gave my 2000 camaro v6.

I put this flowmaster muffler on my 93 firebird and it sounds amazing! For the price this is a great upgrade from the stock sound and it looks great to have duel exhaust. If I were to upgrade I would probably go with either an SLP or Borla exhaust though since they have a deeper and more throaty sound.

The inlet size on the muffler is slightly too large for the v6 93 Firebird so you will have to get some extra pieces to make it fit correctly and I would recommend a good weld on top of that.

I was searching the internet to find out how I could make some improvements to my Mo'. I was excited when I found out that this Flowmaster muffler would fit my Murano, for under a $100 I was able to get my Mo' to sound tough with a great noticeable growl on start up and acceleration. One thing I would recommend is removing the resonator to get maximum growl. At first I went with only the muffler swap, 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 that made a huge difference. I'll try to post a video of how it sounds, there are some great examples on you tube if you type in nissan murano flowmaster. Hope this helps.
