it all depends on what you what to do with your car most. I HATE wheel gap so the first thing i do to every car I first get is lower it. and i've never had an exhaust on my car before but my eclipse's stock exhaust already had a big tip and didn't need to be modified at all since the 2000 model already came with it. And the only reason i haven't done CAI is cuz I dont really care for it yet since i'm trying to go FI ASAP, even tho i might get it for summer to reduce heat bog. and right now im' going to pick up my invidia so if you like it then get it, but you can get the skunk2, i heard it's pretty much the same. Test pipe you dont need i dont think since the exhaust replaces it, maybe a downpipe if u plan on going turbo, that would help.

 

It did indeed. But I didn't see that until it was in front of me.
