Review on Flowmaster Pro Series 13012100 Muffler - 3.00" In/3.00" Out, 12" Length by Matthew Nielsen

It was perfect. Like. LOLI needs two of these and she put them in. No sign of them. I installed them on my 2006 Dodge SRT8 Magnum station wagon. I replaced my factory muffler which was almost dead. The rest of the system is still in stock. I still use standard resonators and this is where I was so disappointed. In fact, the FLOWMASTER muffler was quieter than the stock muffler. They can't go up, I installed them. I had expected a deeper growl, but was denied. There's a different metallic tone here, and they produce a deeper tone when idle. They also sit about 1 inch lower than the standard case they replaced. I'll cut the resonators later to see how the sound improves. I also wanted them because they use Cool Shell technology so I don't have to worry about heat transfer to the rear differential and floor pans. The model I bought was 12 inches long. The name comes from a question I asked the installer as he started the engine. It was so quiet I asked him if he installed it.
