Well I have been interested in upgrading the performance of my 2011 Honda Fit for some times. I wasn’t raised in a really mechanical household. So I have some questions in which way I should be proceed. So far everything is stock. Should I start with a cold air intake?

 

You can't really do anything bolt on except and intake and exhaust for the most part anyways. Both do help the engine breathe and gain some small amounts of power. The car still won't be very fast though.

 

Don’t expect much besides more noise. Intake might net you a few HP.

 

Would a (1) cold air intake, (2) new exhaust header, and (3) axle back exhaust give more power?

 

James,

I have had a full Spoon catback on my car for about 2 months and I have noticed a pretty big torque gain. I haven't dynod it but everyone I let drive it or who rides with me always says it feels much happier and revs up much quicker. So in my opinion a nice catback would help you find some torque and HP.
