cobb tuning... Does not make a intake for a 99rs but it can be made to fit contact danzborin he can help ya

Injen... Does make a direct fit and it is a great intake so i have heard though its pretty difficult to change the filter due to the filter being in the fender

Ganzflow... I have basically the same as a short ram intake that ganz sells for the rs

i like the latter due mostly bec keeps lowend but i would give my left foot to get a cobb but im pooo

If you want deep, you can go w/ greddy evo... w/ borla headers...

Might not give you the best gains, but will have a nice sound and be fairly inexpensive... Depends on what you are looking for...

I am running MRT headerback, except am running the EVO muffler. Sound isn't near as good as the borlas, but the power is far better...

oh thanks. i cant really find that many places that sell injen intakes though.

Yeah i was looking for a power gain in exhaust. I was either thinking about a brullen possibly?... or i like the way the blitz nur spec looks, its not too big and not to small. But i want something that wont give me a headache on long trips.

how would a blitz nur spec sound with a stromung mid pipe?...

also is a scooby sport really loud?...

my price range is around 500 to 600.

thanks

the blitz is very loud from what i understand... for quiet, mrt's muffler is one of the most quiet... EVO is too, but not very understated looking...

Intake:
-take care in what you buy. I've done data logging of my own car fiddling with the intake. I found stock to be the best outside of pulling warm engine bay air. Removal of the stock airbox is bad. The plenum volume is tiny on these cars, and they do seem to need the stock air box to act as a secondary resonator to damp and even the incoming flow of air. This includes how well the MAF reads airflow and can affect air/fuel ratios. I have a Phase II SOHC motor with the MAP, but it still affects air/fuel if removed despite the sensor being right in the middle of the plenum on the intake manifold and will affect MAF more so. An inline resonator between the MAF and plenum is important.
-most of the gains of a modified intake is the pull of colder air. You can gain anything in the neighborhood of 5-10 ft-lbs from the difference in temp alone.
-modified intakes typically lose power. Yes, we see gains from the colder air but there are also losses due to less even flow. The engine power tends to rely heavily on the ECU tune. Most of what's affected is in the 2000-3000 rpm range, and a lesser design can see a drop of 10 ft-lbs here.
-you will see zero gains on the top end form modifying the intake. Other than the universal gain from colder air, there is no flow restriction from the stock intake, zero. The intake manifold and heads/cams are the driving factors to the flow level of the motor on the top end. I've gone as far as sticking a filter right on the throttle body (yay for MAP based), and compared directly against the stock intake. There are zero, and I do mean zero power gains on the top end due to any flow restriction. This includes me having a full exhaust. The heads/cams are the main limiting factor, not the intake.
-with all this said, it should be pretty obvious that the stock intake will operate best. BUT, it is helpful to modify the intake point and actually pull in actual cold outside air. This is why people step to a hybrid package, running the stock airbox, but feeding a custom pipe from the fender to the airbox. It's done because it is the best package for this car. If the intake manifold had a bigger plenum, it probably wouldn't matter so much, but the way it is, you want the stock air box there. It is possible to tune the ECU and tune around the lack of the airbox, but you have to tune the ECU for it to not get a dip in the midrange and messed up air/fuel. I'm only basing this off my MAP based car which should be less sensitive than your MAF based one.

Simple things from exhaust:
-the header is what makes the power, get one that's guaranteed to offer moderate improvements, i.e. TWE.
-piping post header does not matter that much as long as it flows freely. Typically what fits the header is fine, and I think a TWE is 2.25". Toss in a high flow cat (300 cell spun metal substrate from Car-Sound (Magniflow)), and then whatever muffler package that will get you the end sound you want. Typically any straight through exhaust will be rather loud on a NA car. You will at least need to add a resonator/glass pack to tame down the output.
-mufflers are pretty simple things. In the simplest form, it's a resonator, just a hollow chamber for sound waves to bounce around and dissipate. It acts as a low pass filter, cutting down higher frequencies. Bigger resonators start rolling off lower. A glass pack is an improved form of a resonator. Really they don't use glass fiber anymore for the most part, just metal like a steel wool pad packed into the chamber. This helps trap and dissipate more sound energy and improve the sound reduction performance. Straight through mufflers are effectively glass packs, just bigger. Things only get different once you step to chambered mufflers like that of oem. These are tuned devices that tend to cut out sound the best, hence stock being very quiet. They are also the most restrictive of designs since the air has to flow back and forth through the chambers before exiting.
-the choice in glass pack and muffler package depends on what you're shooting for. Expect to run at least two noise reduction devices to bring the volume down to an adequate level so the drone won't be annoying and neighbors won't hear your car from a mile away. In stock form, these cars run a resonator and chambered muffler, along with several cats, to reduce the volume level. Stepping to one high flow cat will bump up the volume a bit. Saying bye bye to the mid section resonator will bump up the volume a bit. If you stick with one of the cheapy aftermarket exhaust packages, it will have a pretty basic muffler that won't reduce volume levels all that much. It will be quite loud. However, you do have the freedom to modify a package. For example, you could get an exhaust package and add in a glass pack to the mid section.
