im thinking about getting some
headers but are they really worth it

also will my exhaust be louder??
im currently runnin' an Injen short ram intake
with AEM Dryflow filter and Blitz Nur-Spec exhaust

 

I got 4 hp with MMW 4-2-1 stainless header. I dynoed it before and after.

I have an auto, if you have a manual you might get a small bit more.

The exhaust will sound the same. I was expecting to hear a diff when I installed my header, but there wasnt really any.

If you get a good deal on one then its worth it. I cant remeber how much I paid for mine... I want to say $100 shipped, maybe? It was an awsome deal.

You might lose a little torque in the low end, but you get an increas in the 3k+ RPM range

 

what were your numbers?

 

hehe... low
I'll get the dyno graph

 

just over 4hp

blue is before
red is after

 

i have the weapon R 4-2-1 headers, i noticed a slight power increase. I have the 5 speed. It did sound a lil deeper. I have the hks exhaust and intake. It sounds really nice now.

 

isnt weapon R the same as Monster Moter Works?

 

I have the weapon-r/mmw header and I am very happy with it. I didn't notice a change in volume but I did notice a definite change in tone.

 

wow, your powerband is all over the place...

dyno issue??


also, i didnt know they made a 4-2-1 header for the xB yet...awesome

 

not realy

 

1.5L 1nz-fe?
80+hp at wheels?
i'm having 101 PS on wheels with stock header

 

well good for you


the 108 thats advertised is the flywheel hp

80 is actually what just about every 1NZ-FE gets to the wheels, some variables like drivetrain and altitude can change it

 

I'd like to do another dyno run with stock 15" wheels. Too bad I got rid of them like an idiot

 

hey so which are the best headers available out there for the xb
that will give you the most horsepower for the money???...

DC Sports, Strup, Megan Racing, etc??

 

WEAPON R / MMW

 

Nice to see some before and after numbers.....maybe I'm just not searching enough, but it seems to be a rarity with the XB

 

I have a K&n intake.
Should I get headers or an exhaust or both?

 

both

 

both if you can.

 

I'll have to spend some money then.
Now I have to ask:

which brands?
