Plus I'll probably be able to sell my Stillen CBE after I make the switch, which will further help me recoup my investment. So no worries.

i may interested in your Stillen CBE! what part of Atlanta are you in?

I've seen the same car dyno with different numbers on the same day! I still don't see where it's 'proven' that the FI CBE is making more power than others. How some folks can say that this doesn't bode well for Stillen's CBE is beyond me.

And FI has an advantage where they could tune the LTH using their own CBE.

Actually, I just got laid off. I'm out of work as of 5/21, so disposable income isn't what it used to be. Oh well, c'est la vie.

Wow man, I dunno if that's ballsy or just stupid.

If I knew I was going to be laid off I would be saving every penny to make sure I can survive the possibility of not having a job for a few months. I'm assuming you have quite a few months of savings put away but still, I think there would be better things to spend it on than performance parts for a car.

Good luck in the future though!

One reason I would think the FI makes a little more than others might be the fact that it really has little to no turns which cause restriction. That would be the only way I can see it making more, and maybe only 2 - 4 more IMO.

I'm not sure what your point is. Is this supposed to contradict something I said? I'm more interested in the curve than I am in the numbers themselves.

You're also forgetting the fact that its long tube design eliminates the catalytic converters, freeing up HP/TQ there also.

The reason why most headers on newer cars (of normal design, not long tube), is that efficiency can no longer be found in designing normal equal length tubes. Factory OEM designs are so well made that it is difficult to notice any real difference in power by upgrading headers. Nowadays headers are mainly designed for tuning the powerband, which is why other headers for the VQ37 have really only shifted the power band one way or another, and power gains have been negligible.

What makes this so different is twofold: it eliminates what is arguably the most restrictive area of the exhaust- the cats, and the longer tubes down to the collector located downstream probably even out the airflow a little more. Those two factors, and the one you mentioned about less bends in the header design, probably account for most of the power gains.

Let's not forget that semtex's review is based off of high-flow cats and a stillen header vs. FI LTH and he already got a noticeable power gain. I'd also like to point out that he's running the Stillen CBE.

I'm curious to see what the FI LTH would do on a car with bone stock exhaust mods to quell any debate over FI LTH w/ Stillen CBE vs. FI LTH w/ FI CBE power gains. I don't really think it matters which CBE you pair with these headers, it will definitely make a difference with either provided the exhaust diameter pairs with NA builds.

No man, just busting ballz. I'm one of the ones who LIKES your new dyno graph

Ben, did any of your studs come out when taking the stock headers off? Virtually all mine did and i'm not sure what the proper tool is to remove the nut from the stud-bolt. I also stripped one of those little heat-shield bolts on the drivers side

Torx. If you don't have one, an easier way to take it off would be to use two bolts. Same thing with threading them back into the head. Stack one on top of the other.
