I'm currently looking for an exhaust setup for the 2003 grand prix gt 3800 3.8l v6 in my gfs car and I know what I want but its starting to get the best of me cause of all the dang r&d I'm doing to figure out what will work and willn't work. The main focus is I want (4) 4in double walled rolled slash cut tips! Now heres where I need help do I do a full exhaust kit and pour a ton of money in to a pre-assembled kit only to hack it up so I can have the tip setup I want or what? Whats the best route to go as well chrome or polished tips which will handle the heat better even though I looking at double walled tips? Please help me here as I want flow and looks over sound kinda need to keep it on the quiet side so as to not disturb neighbors at her apartment.
