TTI exhaust too loud

If you want something like glasspacks but not as "machine-gun" sounding and without packing to burn out try PowerStick mufflers by Classic Chambered (custom muffler shop in Michigan). I have the longest (26") ones in a Pypes 2.5" X-pipe system in my mild 318 Duster and it sounds great. They're a little drone-y at lower speeds but once you get over 55 MPH or so it really quiets down. And when you punch it the car has a nice loud, deep and "open" sound that isn't raspy or poppy. Very similar to the factory exhaust sound but louder and more open-sounding.
