I have a '95 Silverado with the 5.7 L 350. It currently has the stock exhaust, but I am looking to give it a bolder and more aggresive sound without draining my bank account. I want to install a new muffler and keep everything else stock for now. As of right now I'm thinking of getting the Flowmaster 40 series original (single in/single out). Has anyone else done this and are you happy with the results? Any suggestions on different mufflers to consider for that aggressive sound? Opinions?
