^^^^This! This is exactly how i feel about headers. And on the last part of your post i couldnt agree more!!

 

Hey stevednmc, Where in Nebraska do you live? I'm in Lincoln.

 

So buy kooks.

 

@Boris, Im in Omaha. We're practically neighbors!!

 

What could one expect from a stock GT with bolt-ons such as off road H-pipe, CAI, programmer and cat-back exhaust? 4.10 gears, too, but that's more of a SOP than an actual HP gain. Thanks.

 

Thats essentially what we have been discussing here, What to do to get 300FWhp. My guess is those mods would get it close, but not at the wheels. Are you looking for possible ET's as well?

 

It'll vary slightly depending if it's auto or 5spd. The cat-back exhaust is more about preference of sound then actually horsepower (won't be seen on a dyno). The CAI is is worthless in our model of cars, it'll add maybe 1 ehh 2 hp tops. Now the 05+ Mustangs (respond to this better). I'd say with o/r h pipe + CAI + tune = 230ish rwhp. Those gears however should help your ET at the track though.

 

It's an auto, and thanks for the input. I don't drive the car daily, so I think 4.10's would be good for performance and the higher cruising RPM would sound good for.. you know, cruising. :P Any idea how horrid my gas mileage might be? heh.

I may forego the catback. I have Flowmaster 40's welded on to the factory system now and I love the sound, I just want more of it, esp. at lower RPM, hence the o/r H-pipe.

That's about it for performance for now. Down the road maybe cams, throttle-body, etc, but for now, I'll turn most of my efforts to looking and sounding cool :P I have access to used lowering springs and o/r H-pipe and maybe a programmer.

300rwhp n/a? I am guessing head work and cams minimally (or trick flow heads), right? Might also look at a 5.4L swap, as a cheap swap. Then again, if you're gonna swap motors, a 4v makes sense... maybe that's going too far

 

k&n cai is worth atleast 7 rwhp.k&n claims 10 hp, i bet it does, or atleast real close. 99% of people on here will tell you it dont. but what do i know i only been doing this for 25 years.

 

I am auto too. Skip it looking "cool" for just a bit. If you go out and get a stall converter Look into a 3800-4200 stall (you'll need it b4 you can even touch the cams). I'd also get a shift kit pairing it with a transmission cooler.

^ You do those things & trust me from the line, light, and tree you're in the money. The other car is gonna have to have some "goodies" to catch up after you haul-out quicker then snot.

Your gas mileage prob will take a 2ish mpg hit.

Yes, and my BBK throttle body claims 10-15 wrhp & my plenum too All that is needed is a K&N drop in (re-useable filter) the new edge style cars already have a CAI in place. It wouldnt net you anywhere close to 7 rwhp. I have access to a dyno & have seen K&N, Steeda, C&L, AM, BBK, etc (only) on GT's auto & 5spd.
