Guys I need some perfomance upgrade advice for my newly acquired 2010 4cyl Camry, yes I know its an oxymoron but why not inject a little go-fast. Been researching KN intake and any available exhaust/ header mods. Send any info or manufactures that you have experience with.

 

The cold air intake will gain nothing.

A CAT back exhaust might make the engine sound better. Look at Borla. Try OBX for headers.

Suggest checking out Toyota Scion tC support forums for cars having the same engine. Scion owners are more involved in engine mods.
