My 05 Grand Prix GT is completely stock besides a Cold Air Intake. I dont want to redo my whole exhaust
system or do anything with mufflers. But was thinking about removing my resonator and replacing with straight
pipe or replacing with glass pack. I've seen a lot about removing the U-Bend or using a Downpipe also. I'm not looking to spend a huge amount of money. I also don't sit and rev up my engine. I just want something to improve sound/performance. Any advice is greatly appreciated. Thanks!
