5.0 out of 5 stars My camaro never sounded better, August 17, 2008

This review is from: Flowmaster 42583 80 Series Muffler - 2.50" Offset In / 2.50" Dual Out - Aggressive Sound (Misc.)

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.

5.0 out of 5 stars Great Throaty Gurgle!, October 15, 2010

This review is from: Flowmaster 42583 80 Series Muffler - 2.50" Offset In / 2.50" Dual Out - Aggressive Sound (Misc.)

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.
