which header to go with and why?

[burdickjp]

I would caution to avoid an unequal length manifold, as large differences in volumetric efficiency between cylinders require different fueling and ignition. If this isn't accounted for then you aren't maximizing power, or worse, running quite a risk, as cylinder mixtures and temps will vary.
If you feel like paying for tuning with individual cylinder exhaust gas temperature probes and individual O2 logging, then you'll get broader torque delivery.

It's not just the catback, it's the overpipe and front pipe which are restrictive as hell on stock pieces. Ask any real tuner.

is Drift-Office not comprised of real tuners? As I said before there are better headers and if OP has money to spend then all means get them. All I'm saying as it's not going to be noticeable and not worth the money in my opinion.

Yes, they're a real tuner, but they also stated the exhaust is stock besides the header. Even Bob will tell you that car probably would have been close to 200 whp without the restrictive overpipe and front pipe combined with it. You can tune more aggressively with better scavenging than the crappy borla collector that doesn't scavenge near as well. An engine that can breath better will always produce more power.

It's half the definition of an engine producing power.

overpipe and front pipe are shown to be pretty dismal for gains given the $$...

The cats are restrictive yes, but the piping size of the header is what makes it the most restrictive. Since the exhaust gas is considerably higher temp than when it hits the FP or OP, the larger the pipe the better it is for exhaust velocity. (To a certain extent, cant have 5" piping for a manifold, that wouldnt hold enough velocity for the gas).

After the exhaust gas cools down, it compresses (chemistry class PV=NrT.)

Thus the exhaust diameter doesnt matter as much as when its hotter vs colder farther down the system.

Aye I understand the velocity of EGTs and how it pertains to this system.. but realistically speaking, the gains are exponentially worse than a free-flowing header if we're talking gains per $ spent, but I could be so far off that its not even funny.. would have to spend more time researching it

The whole point of a header is to improve flow. Why restrict it again at the OEM over pipe and front pipe? Sure, they don't do much with a stock header, but they flow a lot better when combined together.

Dont worry Ko; im agreeing with you lol

I will be getting aftermarket overpipe and front pipe down the line also. But for now, just getting uel header and of tablet.

fueling and ignition? is that fixable with tune? I am getting the oft for tuning. I like the rumble of uel headers, Im aware some el headers can produce more power than uels. I'm definitely not running the headers without the tune, thats for sure, only way to get the most out of it anyways.
