Do the headers include an xpipe? Chase, would you mind PMing me the details of what comes with them, as well as a price to 13037

Check out the graph fellas.

Like the key says, Red lines represent the Pfadt results while the Blue are the stock numbers.

Obviously from a ZL1 car but still should be relative none the less.

The lower pair of Red and Blue lines represent Horsepower (Hp). Linear from 2000 rpm to about 6200 where it's shutting down/cutouff.

The upper pair of Red and Blue lines are the Torque (Tq) that each is representing. See right off the bat at say 2200 RPMs the HP is right around 200 but Tq is way up at almost 460 ft/lbs.

This is right away tells us that the car, in this case, was made to have more Tq at lower RPMs to help get it rolling and off the line fast.

(sidenote-check out how the torque "curve" or line in this case shows 80% of the total Tq that is made for the car happens within the first few hundred RPMS of the cars Dyno. Pretty cool that you don't have to rev the heck out of it to make Tq!)

The Torque gain, without a tune mind you, is almost 20 ish higher at just 2200 RPMS. Furthermore, and some folks never see this, is look at the "separation" of the two Tq values all the way across from the 2200 RPM all the way up to almost redline. The gain of Tq is all the way across the power range.

This is another feature you don't usually see on a standard non Tri Y header.

You can reference the Hp lines and see that gains are exponentially higher with RPMS...meaning, it gains more Hp with more RPMs up until about 5800 where you see that separation start to close.

Hopefully that explains a little more as to what some of the differences are and how to read a dyno sheet a little more quickly and easily.

There are a lot more things that you can get out of this Dyno result but the important things are what I mention and reference as to how the power is made and where it is made compared to a standard set of Long Tube headers.

Enjoy and ask questions if you need some more assistance!!

You have to PM Pfadt to get the price, they are not posting it here. They replied to me pretty quickly.
