Performance upgrades, need help!

Hi there,

I recently bought a 04 mazda 6 3.0 and I'm looking to put some stuff into it to add some hp. I'm thinking of getting a downpipe,headers,exhaust system, intake system, throttle body, front and rear strut bars, short throw shifter.

Has anyone done any of this to theirs? I need to know good places to purchase them from and any ideas.

depends on what i can get. what do you have in mind?
For hundreds of dollars you can get 5-20 hp gain max ~ headers, light weight flywheel, CAI,...etc. For thousands of dollars you can get 50-100+ hp ~ turbo or supercharger, meth injection, tuning...etc. If you can do the work yourself you can save a ton. Increased speed is directly proportional to ones willingness to spend money and/or time. :)
Sport compact car tested the Injen intake in their magizine back in 2005(or was it 4) and gained 17whp just from the intake. add the CPE tuner on top of that and it is more.....
My point exactly and how much does it cost?
Oooooo...MSDS HEADERS ......... NICE!:)

Nitrous DOES NOT create pressure within the manifold. If it did, it would just blow/flow backwards out the the throttle body rather down into the cylinders. The tiny volume that is actually injected is no where near enough to create pressure relative to the volume in the manifold.
