Hello.

I have see a OBX Race header for Honda jazz L15a 2007 and i have a Honda jazz L13A 2006. You think i can mount it to my Jazz ?

Thank you.

 

I would think so, the only diffrence is the internals of the engine. the headers should fit with no problem, unless they are USDM version..

 

I would just contact OX and ask them directly...

 

Thank you.

 

Can somebody check or give me some light about the header issue. I took the car to have a custom pipe made to try out the car without th muffler. Being under the car I told the guy at the shop that the next thing that I wiil do to better the performance will be a header, and he told me not to because the fit already has a header (not a big ugly maniful) and he told me to look and it is true , it has a 4 into 1 header, so I belive that the power gains will not be as in former hondas or nissans that when you put a header in them you could feel the defference right away. please some technical help here.

 

Exhaust header 4-1 from Obx fits great on my L13A (from Italy)...

 

You have see good results, more HP and see a Fuel consumption decrease(more low) ?

You must put a O2 simulator ? Or on the L13a we have only one A/F sensor ?

 

So what is the review.

 

I'm still testing the car...
I have panel air filter, 4-1 obx headers, sporting cat, without central silencer... and mechanical O2 simulator on the second lambda (of course).
I'll let you know about fuel consumption in 500-600 km
The first impression is that the car accelerates better at every rpm and reaches the red line very quick, but I'm afraid I should adjust the air/fuel ratio... I think It's become a bit lean...

 

Okay, thank you.

The mecanical o2 sim from OBX ?

I think yes (come a bit lean).

My actual fuel consumption is same you 500-600km, but without Race Header and Filter.

 

Is the stock header 4-1

 

This is the O2 simulator I bought. It works perfectly....

For every question about OBX products I asked Alex. He's very kind alex.hom@sbcglobal.net

I like these headers a lot.... their price is very honest and their quality great.

Anyway I think I'll build a circuit for tmap sensor to adjust fuel ratio....

 

Hello alf74,

How are your Jazz with/and OBX after 1 year(same) ?



you have buy the o2 mechanical sim at alex hom ?

 

I'm really satisfied.... after 1 year
I upgraded the car with air filter kit (home made), apexi air fuel controller, double exhaust, light crank pulley ecc.. ecc..

You can found o2 mechanical on ebay easily..... for 5-6 $

 

For intake, you had put a pipe for take fresh air and a K&N panel or a pipe with custom CAI ?

Good gain ? the fuel consuption is less or more ?

Pulley are good ? what vendor ?

You have really maked gain with apexi ? I have ear this make only change the MAP sensor value and can make a lot HP loss.

 

I should take some pictures to show you the work. I used a universal air filter and inox steel pipe 60mm
Fuel consumption is less. I use a LPG system. With 20-22 � I run 450 km...
Crank pulley is from Summit 龍穎國際產�*有限公司
When you configure apexi you have to know when and what modify of your tmap....
Hp losses?
My car is a missile!!!!

Thank you, yes pics please !

Stock, i found it's a missile. With mods.....

 

Yes, pics please my euro-friend.
