I had these quoted by livernois Motorsports today, price was 1200 installed including a custom dyno tune. Livernois is telling me that a tune is required but everything i have seen says no tune is required for shorty headers....any thoughts about this?
Is a tune really required, even if it is not is worth the extra money to get the car custom tuned.
I already have the mods listed below in my sig

 

Shorty headers do not require a tune~

 

Thanks GRAYPNY, that is what I thought as well.
that being said, is a custom tune worth the extra money?
input is appreicated

 

shorties aren't worth it either, go longtubes....

 

No tune required. That price is too high as well.

 

I had been researching the whole longtube and shorty header debate and from what I had read recently the shorty's will make better power and torque in the lower rpm range. http://www.mustangmonthly.com/techar...o_results.html
Granted all things being equal, the Lt's will post much higher peak power numbers, especially in the higher rpm ranges, but if the car is a daily driver isn't it better to have more power within the rpm range that the car is mostly being driven in as compared to winding it out to 5500-6000 rpm?
In the future, when I get back into the market to purchase another set of headers, I may have to give the shorty's a serious consideration based on this info.

The price does seem high, even with the custom dyno tune. I think the dyno tune is worth the extra money IMO, especially if you aren't sure what your fuel/air ratios are. With the dyno tune, you'll know exactly where they are at with the mods you have on your car....no guessing.

 

I agree LT will net more power...
but i already have invested in a mid pipe so I dont want to buy a new one.
I have also heard the shorty's will help to improve low end torque/hp.

As far as the custom tune, aside from fine tuning the a/f mixture is there any hp/tq increase that i can expect?

 

I think that price is ridiculous!! Install should be about $400. I think those headers are like $300...you do the math.. No tune is required... Tell them you want everything for $700 installed without a dyno tune... They will probably go for 8...

 

If your having a professional install them, then they should be able to custom cut the pipes to fit longtubes if you really wanted to go that route. As far as the gains from shortys, Ive heard they give you a little in the mid-range, but I didnt notice anything with mine, I only got them to kinda dress up the engine bay a little. Im looking into switching to longtubes myself.

 

That is exactly what I was quoted...
307.39 for the headers
400 for install
450 for dyno time.

I understand that a tune is not required...
I guess I am wondering if it worth having it done just to get the car tuned.
guess I am wondering how much better a custom tune is vs. mail tune from alternative auto.
