Your not gonna find too much. I wanted low end and got exhaust and Cold Air Intake and wasnt happy with it. Supercharger is the only thing that will add a lot of low end but that is a lot of money.

My exhaust is 2 1/4" all the way to the front...I heard that you can actually lose low end torque with piping that big, you think that is true? I thought it was only with 2.75 or bigger.
What type of Intake should i get...cold, Short Ram? and what brand you recommend?
You think headers will do much?

TPR Cold Air Intake. Headers won't do much. There aren't any good ones available for the GT, as far as I know. You can lose low end torque with any large exhaust. The larger the exhaust, the less back-pressure, yielding more high en and less low end.

Do you lose a lot of low end torque though?
Also until about 2500 RPMS the exhaust is loud and deep, after that it's high pitched, is there anything I can do to make it sound deeper?

Also I forgot to mention that it is an automatic...

With an automatic, you're really pressed for what you can do. The auto GT is the least mod-able and the slowest. The only thing you can do to make a real difference is to supercharge it, and that's really tough. There's nothing you can do to make it sound deeper. The cold-air Intake will provide some growl throught the upper rev range, however. As far as losing low-end: No, not a lot is lost, but some loss is inevitable. But what is lost is more than made up for in the higher end.

Well low end is not gonna be more with better flow. Top end will be.
To make more power where you want with your current setup, is only possible with a cam timing adjustment. So I guess the only current chance is and apexi pfc...

The powerfc does not work with the auto. As to the exhaust; The TRD exhaust is the best for low end or the tpr exhaust might be good too. Honestly I would save your money and buy suspension mods. Get either the Hotchkis sway bars or the TRD sway bars and dont pay more than 260 shipped for the hotchkis or 190 shipped for TRD's. I also have a auto and like I said, save your money and use it to improve the celicas great handling characteristics.

From lakewood eh, im in tacoma, basically your neihbor lol, what colors your car? have you done anything cosmetic to it? You should come to some celica meets we have.

As for Intake i had AEM CAI and for us automatic owners it gets you to 43mph when flooring it instead of 40 rofl

Have you seen this car around before? Linked Image

I haven't seen your car around 10celica10, but nice exterior, those are the graphics that I wanted to put on my car, now I can't because you have it lol..
My car is superwhite with the action package on it, exhaust, and on the back where the Toyota emblem goes, I put a TRD emblem. That's about it, I got it about a week ago.
Where are the meets?

Add me to your list if you have aim, my S.N is ooblinblinoo
