Dont buy the AEM intake or the TRD exhaust.
The AEM intake from the dealer is not cheap, and I dont know how they have the intake. Our dealer said its not out yet and pretty much no other dealers have them.
The TRD exhaust is just an axle-back, Im sure little or no gains are seen.
Cheap power goes as far as the tools you have at your house. Take off the air box and run open MAS. Also pulling off that little box on the intake pipe and pluging the hole would free some power. Another thing that could be done is running some sort of cold air extention outside the engine bay. As a ram air effect.
Taking the exhaust off after the 2nd cat would free good power also. Even open header would see some great gains. No need to worrie about backpressure since the cat should create enough.
These mods should be temporary (track runs, street races). Running with no filter is not good for the motor. Other than that the others wont hurt it.

AEM makes good intakes, and it's worth getting it from the dealership. it has the bypass so it won't let water into the engine should you drive through a deep enough puddle, and if it does happen to happen (maybe a 1 in billion chance) it's under warrenty since you got it from the dealer.

It makes the car growl a little more under WOT. More hp? I can tell there is a little more there. For under sixty bucks you can't beat it.

Here is a link: http://www.users.bigpond.com/pgscott...resonator.html
Note it specifically states: Complete removal of the resonator saw a steady loss of power throughout the rev range of 4kW (7% loss!! peak power was 55kW).
Don't remove that resonator until you get true forced induction.

Riemann would be proud.
One major simplifying feature of one dimensional flows is that for many purposes wave interactions can be interpreted as local binary interactions between nearly constant flow regions. This is to say the local structure of a flow is characterized by Riemann problems and their solutions. This was one of the key properties exploited by Glimm in his proof of the convergence of the random choice method. The situation in higher space dimensions is considerably more complicated. Waves can exhibit complex behaviors in both space and time. A simple example is the steady state refraction of a shock wave through a material interface. In one dimension this is easily described by a Riemann problem and yields a solution that consists of a transmitted shock and a reflection shock or rarefaction wave. Momentum is transferred from the shock to the material interface, which causes the velocity of the interface to change after the refraction. In contrast the two dimensional refraction of a plane shock with a planar material interface exhibits a variety of behaviors depending upon the orientation of the two interfaces with respect to each other. This can range from simple one dimensional behavior if the fronts are parallel, through a series of steady state configurations if the angle of interaction is small, to extremely complex unsteady interactions for other configurations.

This can yield greater volumetric efficiencies without the use of forced induction.

NAWS - JdM drift0 tyte life 1/4 mile at a time dawg.
NO2 would be the cheapest power adder if you don't use it too often. All these race headers exhausts and intakes is just not worth it for the price.

MagnaFlow has a cat-back exhaust system. Cheap power gains. I'd have to go with either the k&n typhoon, or weapon R secret weapon short ram + headers + a cat-back exhaust. The 3 in combination should run yah about 900 bucks, Flywheel is about 25-30 lbs lighter than stock and will increase torque numbers above 3k rpms and increase acceleration off the line. that goes for about 500 bucks. never hurts to upgrade the clutch either. Not really direct hp gains but it will make yah faster. the stage 3 from clutch masters is also about 500 bucks. Since the tC has a pseudo cold air intake, you probably could get a couple horses from just a high flow filter (available from trd and k&n i believe) for 75 bucks or so.

you want cheap power, strip out your interior and go lightweight. rermove spare tire, etc etc.
carbon fiber hood and trunk and lightweight wheels. those are pricey but are good steps for power applied correctly.

if i were you, i'd wait the warranty. but i'm not you. you are definitely one who needs to wait the warranty. no disrespect but you really need to wait the warranty.
that whole "keep 'em coming" thing ain't good. imho, you need to wait the warranty.
your pocketbook may be ahead of your knowledge. no disrespect.

Bah humbug I say. I just painted the PVC cap with truck bed liner, how you like that? And I am wearing NISMO badges

Ok, I'm putting the damn thing back on. Just came back from http://www.users.bigpond.com/pgscott...resonator.html and it seems to make sense to me. Oh well. Maybe I can find a vaccum line to tie off for fun...
