Joined about 10 minutes ago. Got some dumb questions. I have an '09 SE coupe and I love it, I want to make some changes to make it a little different. On a budget. I'm retired. I installed a K&N filter. Some improvement. Next I'm looking at a Magna Flow cat-back system. Where to go from there? Chip? Which one? How about suspension? Shock tower braces? Sway bars? Tires and wheels, Can I easily change from 4 lug to 5? Suggestions and opinions will be greatly appreciated.
