Guys

I know Monster Motor Works has 2 headers out for the xB, one is the street and one is the race. What is the difference between the two? Which one will lose low end power?
I would like the pros and cons of both if possible.

Eventhough there are dyno results of the headers giving more hp and torques than other headers (strup, dc etc..) but I don't see alot of reviews of the Monster headers from xB owners? Am I missing something?
I'm definately buying a header after the new year but I would like to make the right choice..

Any comments would be appreciated.

 

i think they only have one header but some posts call it the street header others call it racing. yet i've only seen the pics of teh 4-2-1 one.

 

I believe the 4/2/1 improves low end torque. I have only seen the 4/2/1 from MMW. They have a post on here somewhere with the 4/2/1 hp and torque curves vs stock. It looked good, but some peeps were balking at the price. But they seem to be high quality.

 

The Street header is the same design as the Race version, only with small primary tubes.

 

That is my understanding also.

 

Thanks for the input but I'm not quite understand why peeps are balking at the price when the GB price is $300 for Monster header which is the same as the strup header.

 

I'm waiting for Monster to respond to this thread to explain or to clarify the difference between the headers. I'm also waiting if other xB owners have anything to say about this header. I'm basically torned between the Monster and Strup header. Tough choice

 

the strup is hideously overpriced as well.

 

The difference between the street header, and the currently advertised race header is primary tube diameter. We are currently pending production on the race header, so only the street header is readily available. We may be changing designs on the race header, so no ETA on when that will be available.

 

So how much is the street header and what is the gain? any lost low end power? I can't find the street header thread.

edit: nevermind i just found it since u already bump the thread
