So, i have a 1999 v6 camry (automatic) and i would like to have more power. Honetsly, i have little knowlege of cars but after getting my camry and driving it for a while i would love it have more power. I am posting this in hopes of someone telling me what i can do, where i can buy this, and anything else that could help me or even teach me somthing about my car. please help.

 

first go with the Cold Air Intake System
second go with more bigger Under Pipe ( 2.25 ) will be very nice size

 

switch out from A/T to M/T: The 1MZ is rated +/- 200HP. and ur loosing 12% on the torque converter.

TRD s/c: There's aTRD s/c available for the gen4 camrys.

Intake/exhaust: not so much because the camry's exhaust system doesn't give as much backpressure as others. Its more for looks and sound. BUT you will get some hp. Don't get me wrong.

 

swiching from AT to MT will be very nice but the cost of $$$
with cold air and under pipe or ( HEADER ) will be less $$$ and some HP gain
and do not go for Aftermarket Muffler... ( Ticket'sss ) keep the Original Muffler
with the 2.25 under pipe and stock muffler u still get good sound also

* Don't forget if u are going for Cold Air Intake u Must have BYPASS system on ur Cold Air
