I have a grand prix gt 2001 with a homemade short ram intake 4inch cone and removed tb screen. What would be the best exhaust set up for the best preformance without spending a arm and a leg? I know removing the u bend would be my first thing but what else I don't know where to start? And please don't tell me to go to modding my 3800 series.

My thought is removing u bend and getting thrush glass pack muffler. But I also want it to sound good too soo help?
