NEW 2005 LX SE - Need advise for performance Parts
 

What's up everyone... newbie here. This is my first civic and I want to get some gains out of it. I am on a budget so this is what I was thinking of adding. Any thoughts on certain manufactuers would be great.

Looking to add the following:

AEM V2 cold air
Pullies - Don't know who to use
Exhaust or just muffler???? Don't know who to use

I would appreciate any feedback
