What do I do next

Okay I have a 99 GT, I
put some wheels on it and
a K&N air intake is in the works
Im looking for some quick and cheap
ways to build Horsepower. Whats next?
PS Looks count to

2.5" Magnaflow Downpipe from www.performancepeddler.com is best bang for the $
don't bother with mufflers for HP, just for sound, Summit fully welded are cheap $38 each
Change: Plugs & wires (stock do fine), fuel filter, engine and trans oil, serp belt
Silverstar headlights (looks and safety)
Pontiac decal for rear (looks & safety if you get reflective) on ebay
tint and windshield banner for looks (stay legal)
cheapest HP is lose some weight (stereo, chrome/steel wheels, sports crap in trunk)
run a can of Chevron fuel injector cleaner with Techron in a few consecutive tanks

There is no real cheap way to build HP,so set a goal and a budget and maybe we canhelp.Chico(pops)

With a GT, you're looking at either boost or a cam for power. How much do you want to spend and is downtime an issue?

i don't have a gt but i saw this on zzperformance

i don't know if it will work, but it osunds like it is worth checking out.

osunds = sounds

It's alright if you aren't planning on modding any further, like adding boost.

And you can edit your post if you find a misspelling.

For a typical street car, this is a waste. You lose low RPM HP and TQ. That is where you drive everyday, especially on the highway. These gains are all high rpm, unless you modify your shift points to 6000, you are wasting your time and money here. Notice they show no dyno under 3000, there is a reason for this. Did you read all of this?

My car shifts at 6400.

thats like saying that rockers dont help for daily driving. I have heard nothing but good things about the HV3, and if you are trying to make an N/A build, i think it is very neccessary
