Since this PBM '09 GT is my second G8, and I demoded my previous car . I have plenty of options on what to do with this one. I kept my Solo Mach balanced from my previous car but I want it a bit quieter , but the stock exhaust has too many restrictive points. Manifolds and cats will go for Kooks Mids this time. Next will be the mid muffler and choke down pipes to the bullet resonators. An Amazon search turned up The Total Flow 2.25" dual in dual out muffler part # 33385. Its a magnaflow knockoff type muffler with stainless steel around the perforated pipe and then sound deadener. I was pleasantly surprised when I opened the box to find it is also an X-Pipe muffler. This is perfect for the person that has solo axle backs but wants better exhaust flow. replace the Mid muffler and pinched pipes with this muffler and a 2 sections of pipe and you will have way better flow and sound. at $36.78 you can't beat the price. Will get some internal photos soon.
