It really depends WHAT power you want to increase...high revs top end, or low end crawing torque. The header will help with the high end, and hurt at the low end.
If you are trying for better high end power at high revs, then the header might help, incrementally. If you are trying for more low end umph when 4-wheeling, it probably won't help much as it will NOT help power at low revs, it might even cost a smidgen of low rev torque. Tricking engines with aftermarket exhausts or different camshafts tends to move power up or down the rev band...there's no free lunch, and you are dealing with a pretty low power engine. MAYBE I got 5 HP at top end by replacing my whole exhaust system...a guess on my part.
If you have a damaged exhaust manifold that needs replacement, if you want to setup your exhaust so you can use $80 after market flanged catalytic converters instead of $700 stock catalytic converters, if you want to increase high end power a bit by also replacing the rest of your exhaust, THEN an after market header might make sense.
Otherwise, it probably isn't worth the money or effort:
1. If you don't replace the rest of the exhaust you won't see any benefit because the stock exhaust and tailpipe will prevent increased flow.
2. If you DO put on a less restrictive exhaust you will increase top end power some, but also at the cost perhaps of low rev torque. If you want to drive 70mph on the highway, great. If you want to crawl up that steep rocky slope, not so useful.
I DID put a header on my main Samurai...that I retired with 250,000 miles, and it had been used as a daily commuter as well as for week long off road desert camping trips a couple times a year. I did increase my top end power a little as I also replaced the rest of the exhaust...at a cost of low end torque. But since I also had changed the gear ratios of the transfer case and both differentials, the loss of low end torque did not adversely affect me. (My "crawl ratio" was about 78:1 in low range 1st gear, 78 revolutions of the engine for every revolution of my wheels...would idle at 1mph, redline about 5mph, so a slight decrease in low end torque didn't matter.)
On the other hand I did NOT replace the exhaust header on my son's Samurai...I would have done so if his original exhaust manifold cracked and needed replacing, or if we were going to change his catalytic converter. But since neither was needed, we kept it stock. And he had about 180,000 miles on his when we retired it.
Hope that helps,
Paul

what can be added to gain horsepower to the air intake of a 2.2L Pontiac sunfire?
depend on which version you are playing samurai is an additional army which added by one of the custom patch maker install omega patch 1.3 u will get samurai
port numbers
I added: Hypertech chip, K&N air filter, headers with dual exhaust. The best improvement came from the headers.
In terms of internet technology various Headers are added to data to aid in the process of sending and verifying data.
I added a pic
A 2000 RMX 250 has a horsepower of 58. This is based on the basic edition motorcycle. Should aftermarket performance parts be added the actual horsepower of the motorcycle will increase.
The oil to gas ratio for a Suzuki DR 80 would be 1:32. This means that for every gallon of gas that is added, 4 oz. of oil must be added as well.
There are many wild and outlandish claims out there about how much horsepower can be added However independent tests seem to confim most kits will add about 20 extra horsepower.
Yes they will bolt up but you will need to get a second bung added to the exhaust since 1984-1995 headers only have one bung and 1996-2000 have 2 bungs for the secondary o2 sensor.
Brake Horsepower doesn't "do" anything, it's a rating of the engine's power before any parasitic loads (alternator, transmission, water pump, etc.) are added.
