All of this COULD affect the mileage. More exhaust out means more air and fuel can be pulled in. The intake, supposing you are going for performance, will also allow more air and fuel in. Of course, if there is a bottleneck elsewhere (the fuel delivery system, etc.) you won't see a change in performance or mileage.

Yes and no...In theory, you'll see very little difference in fuel economy and technically speaking, a more free flowing exhaust can possibly improve mileage - albeit minutely.However, one also has to take into consideration what effects such changes will have on the squidgy bit found behind the wheel. If one has the notion of extra performance, then it's completely within the realm of possibility that they'll rev a little higher, drive a little harder, accelerate a little faster, etc... If one does so especially because they like the sound it will make, then they generally tend to be more apt to goose the throttle in order to produce the audible goodness... Otherwise, what's the point of doing so if you're going to baby it with a light foot? Either way, no matter which way you cut it... Just remember - there's no such thing as a free lunch, especially when it comes down to performance vs. economy. A preference for one almost always comes at the expense of the other.

You will notice a difference.The engineers that have developed that engine have done a reputable job and any messing with it on your part will have some effect be it fuel consumption or reliability.

No! The only thing that will effect your gas mileage will probably be sludge build up.

The trouble with it is you wont keep your foot out of it after doing all of the mods on it so your gas mileage will go down.

Opening it up with an intake and exhaust should actually increase your mileage a little bit, as long as you manage to not push the petal through the floor everywhere you go.

setting up all these parts will change your mpg,if you take it easy and drive normal then your gas mileage will be better then before.if you where to smash hard on the gas pedal then yes you will go just a little faster then before,hence mpg goes down,but you will still lose to a stock RSX.-YES,add those parts the car will sound good and look nice cruising around town
