I'll post my findings once I get my header. I'm already at 169WHP on a mustang dyno without tunning.

[briantran123]

Intake, header, over pipe, front pipe, catback, crank pulley and Ecutek. install everything in one day and tune it.

Hmmm..
HKS EL header is pretty expensive..

Tomei EL header on the other hand is half the price though.

Are the front pipe and overpipe worth the extra money?

Would I pass inspection with just the Tomei EL header and Greddy SP Elite?( if I were just to get a tune with those)

Would I pass inspection with tomei header, sp elite, hks fp, and motive op?


As much as I would like to squeeze out as much extra HP n/a, it does get pricey after adding up additional parts that may not be necessary for me....or seriously might as well spend extra and go FI.


If I were just to do some spirited driving and maybe track 1-2 times a year would I need an oil cooler??

Passing inspection will depend on where you live... I can pass inspection on a catless system here...

I definitely need a cat where I live for emissions.

Does adding a header and axleback remove the stock cat?

yep, you can buy a catted header, like the HKS, P&L, and JDL EL... or if you want UEL FT86SF

Stock tune is garbage for reliability. First thing I would get is a tune. Then header and drop in filter. If you need a cat, either leave stock front pipe or buy a catted front pipe. Don't use a catted header, it defeats the purpose of a properly designed collector.

What do you mean by stock tune?

I'm just confused because you say to tune it before I install header and air filter?

Also would upgrading to a aftermarket catted front pipe be worth it or just keep stock front pipe?

Thanks!

This is why i will be removing my power blocks soon and selling them and retuning to make sure everything is still sound after the removal.

If i remember correctly when i had mine tuned after about 6500 rpm my power dropped drastically compared to other vehicles with similar mods. Only difference was i have the power blocks installed. Once i remove the blocks im hoping it will flatten out my power band after 6500 through closer to red line.

That's just not true for all headers... where they make power depends on the design, just look at the nameless headers that make the bulk of their power increase in the midrange. Yes there are gains up top as well, but they're primarily designed for usable power in the midrange, not a couple extra hp at the very top of the RPM range.

Typically 4-1 headers shift power higher into the RPM range while 4-2-1 give a big bump in the middle, but that's not even always true until you compare if they're stepped or not, what diameter tubes and what length the tubes are.

Also, if you look at dynos pre/post manifold spacers, you'll see that you aren't really losing much power up top, it just seems that way because of the big bump they give around 6500 rpm. Forget about peak numbers, area under the curve is what makes the car faster.

[Luis_GT]

True... the spacers dont increase peak power by much... but it makes a noticeable differene in the mid range. UELs also make very noticeable gains on the mid range but not much at top end... unless you want to be thrashing the engine all the way to 7400... having peak power lower in the power band is better for day to day driving... and helps male the engune last a bit longer.

Was wondering if it's possible to run a UEL header with stock tune while I get my other hardware in before doing a complete tune once. I know the "gains" will be minimal, but will it have any adverse effect instead?

Thanks

FT86SF uel catted header can be used without a tune... as long as you have the rest of the exhaust stock... otherwise the car will run lean and throw a cel. If you run catless you'll have to use o2 spacers so that is doesnt throw a cat code until you can get it tuned and deactivate the sensor

Sure its possible. Is it ideal? Not really.

Your car may run poorly and certainly will have a CEL which will prevent the use of your cruise control. You can "fix" it with the O2 spacers but a tuning solution is obviously the better choice. As for "gains", I doubt you'll have any. In fact without a tune I'd venture to say your car will run worse than stock with a catless UEL header.

Which tuning solution are you going with? If you are going with openflash, there's no reason to wait as you can flash the tunes as you upgrade the car. If you are going with a different solution my recommendation if you don't want to tune more than once is to just wait until you can afford the whole thing and do it all at once.

I see. I will be running stock header downwards, I guess the only issues I would have to worry about is the CEL.

I am looking at a solution by ECUTek, doing some initial research which I wait for my headers to arrive. Well, since that is said, I guess I'll invest in a tune alongside the installation of the headers. What's sound without the actual power right?
