you will only get power out of an exhaust for our cars (of the two options that you listed). intake is SOUND ONLY with our cars


there are soo many different ways to go about power increases and it depends on how deep your pockets are

there are MANY things you can do. don't listen to what others say. 5at's can be fast. rick is proof of that. he was the n/a beast and he is a 5at.

hopefully you will learn quickly that there is a lot of useful information on this forum and youre not the first 5at that wants to make the car fast or ask how to do so......with that being said...the search function will be your best friend if you learn to use it correctly

look into fast intentions, stillen, and hks for exhausts

look into the stillen intake

in addition, fast intentions (my choice of high flow cats...but also look into other brands such as crawford when doing research) test pipes/high flow cats, plenum spacer, sway bars, coilovers, strut bars, etc.

thatll keep you busy for a while...

but if youre really looking for performance, save your money and go f/i

This is true except when you get a piggy back or air/fuel controler. I have an intake exhaust and spacer with a apexi air/fuel controler and im hitting 13.8...not many auto coupes can say they have done that with those mods. If you plan on running a piggy back system later def get a cold air intake. As far as exhaust get whatever one you want they are all within 4 HP of each other just about.

Oh yea...5AT's can rock!

NA or FI...AT is the way to go. More traction control at launch, etc. Not great drift cars though..gotta have MT for that to be right on.

PM me for some insight...as HERO said about me. I try not to go too public with info anymore...non believers tend to roust ya...usually because they couldn't do it themselves and are jealous

Great advice!!!

The best advice though...plan your attack and budget for it. Everything should be done in certain order, otherwise you'll put good money after bad until other things come into play.

BUDGET BUDGET BUDGET...when you realize your going to spend a certain amount of money on bolt ons...you may realize that FI makes more sense for the bang for buck!

5AT's can be fast if you want them to be

members have given excellent feedback on the stillen exhaust in terms of performance and sound. however, i personally hate the way it looks

you don't necessarily have to get matching brands when doing i/e.

like i said, check into fast intentions, stillen, and hks.

and if you plan on going f/i then plan now so you dont waste your money on something that you wont be able to use later.

good luck.

what does the piggy back or air fuel controller work with your car? how much do they usually go for? What type of performance does it produce?

i just looked into both fast intentions, and stillin. And they said fast intentions gives you 11whp and 9 tq. And the stillin gives you 13-15 hp and 16-18 tq. Which should i go with?

The Stillen will not give you those results...more like 8HP and TQ. Virtually all exhaust systems out there are with about 5HP from each other.

The choice is yours for look and sounds and performance desire. It all has to package properly for YOU.

You really need to search more...BUT

A piggy back controller intercepts the factory ECU signal to adjust A/F mixtures. When you start adding breathing mods, the car will lean out, and you need to tune it to get the most out of your mods as well. Depending on how deep you are ultimately going to mod, will depend on whether the $300 or the $1,500 solution is needed.
