ok guys, Im seriously considering sawing the stock muffler out from under my Tahoe. Due to financial reasons a cat-back is out of the question. I want something fairly aggressive sounding, but without attracting the attention of the noise police. With minimal to moderate drone. I have had Flowmaster Super 40's on other vehicles in the past. Love the sound. But maybe its time for a change. So if you guys can give me some ideas on sizes, makes, models, and part #'s would be awesome thanks.
