Since there was talk in our race header thread. This is our street header that we have available. We will be applying for the CARB approval.

 

Any tests at all with this header? Doesnt take much to slap it on.
I can pull and install a header on my Fit in about 30min. Damn those MR headers!!!!

 

we have a few sent out for testing but i would have to find our dyno sheets. the install is very simple not trouble at all

 

I have the Weapon-R competition street header on my car and i'm loving it. Exhaust note has gotten a bit more aggressive, and I definitely feel a bit more response in the low end.

 

So.... when can I get one?

 

This item is available now.

 

 

Is the header threaded for the O2 senser I can't tell from the pictures?

 

Yes. Ive seen back views of it. Theres an o2 bung.

 

yes there is a bung for the 02 just not in the picture

 

Theres no info at all on this header. What size is the piping, any dynos, anything?

 

I checked the weapon R website.

Weapon*R Racing Development

it says the collector is 2.5" and that it eliminates the cat?

How can you guys be looking for CARB approval AND calling this a street header if it eliminates the cat?

I think the description may be wrong.

 

It clearly does not eliminate the cat. Thats wrong.

 

The description was copied over from the Weapon R Race Headers.

 

Thats helpful.

I do like that its actually a 4-2-1 rather than a straight 4-1 like most shorty headers. Really curious about the gains.

 

anyone want to come down with a 5spd for a dyno test?

 

I agree with potato!

 

ugh. if only san francisco was in the IE hahahah.

 

If someone is interested in a dyno we prefer it to be 5spd

 

has any one donated their car for the dyno for this header yet?
