"This was easy to install with a lift and welder. Great V8 sound without the vibrating or rattling, like other mufflers. Loud enough to let everybody know without waking the neighbors. Would recommend adding a coat of high temp paint to help with the rust." posted by: on April 7, 2011 view all 2 reviews

"I own a 2004 Cadillac Escalade with the 6.0 engine which has the dual inlet / dual outlet muffler setup from the factory. I wanted the 40 series, but the 40 series doesn't come in dual inlet / dual outlet setup. But the 50 series Big Block muffler does. So, I was forced to get the 50 series. Everyone tells me that the 50 series is the better choice for a refined suv such as the Caddy, because it is loud, but not offensive as the 40 series. They say, " it goes with the truck"" posted by: latrae75 on September 18, 2008 view all 1 reviews

"The Flowmaster 50 muffler is awesome. It has a great outside sound while still being quiet inside. I installed it on my 01 Yukon. The price is awesome for what you get. And you know the quality will be there with a Flowmaster. It sounds powerful without taking away the luxury look and sound of my SUV." posted by: on March 11, 2011 view all 2 reviews

"VERY KOOL SOUND!!! I just replaced my flo-master with this Kool Veu Muffler it looks much better and dose not have that nasty drone. This Muffloe is not a show piece but could be if they spent some time dressing the welds befor chromming. The Chrome if good quallity looks heavy hope it lasts through our Colorado Winter." posted by: Lill Red Wagon on September 22, 2011 view all 5 reviews
