Hello, I am fairly new on here.. I don't know much about modifications on cars, but I do know that I want to put some mods on my 2.4 to gain some hp... What mod should I start with to get myself going for performance mods that will truly gain some hp? I am planning on doing a custom catback, but I want to do a motor upgrade that is fairly easy to come by for the 2.4s that will gain some hp. Thanks!
