Well I was gonna put a dual exhaust on the next time exhaust work needed to be done but I thought it would be a while. My muffler seperated at the front pipe/muffler rusty seam during a road trip this weekend. I pushed the muffler out of the way of the "new" exhaust outlet under the truck and got home.<br>Wow my truck runs great now, I can tell a big difference in power.<br><br>So now I need a Flowmaster or something, I want a deep/quiet sound (quiet for long road trips but respect generating when I accelerate).<br>My truck is a 1989 F150 4x4 automatic in great shape, with a 5.0, stock everything.<br><br>Will stick with a single exhaust for now. Looking for advice/opinions. Flowmaster? Borla? Other?<br><br>TIA,<br>Mitch<br>I love my truck
