Vibrant or Weapon R? Fill me in on all the info. There both 2.5" collector. Both 4-2-1. Both long tube. Vibrant has a highflow cat.

Whats better?

 

probably vibrant ...isnt vibrant mad expensice though?

 

My friend doesn't care about price. He wants performance and sound. Quality is important. Just want some specs on each and personal opinions.

 

Weapon-R isn't coated, I don't know if the Vibrant Header is. And are you 100% sure that the Vibrant is 4-2-1 design? I could have sworn it was 4-1...

What kind of car does your friend have?

 

4-2-1 and considering this is the 2.4 forum, its a 2.4 ss. Vibrant is a T304 Stainless Steel.

 

Actually, you're incorrect. It's a 4-1 design.

 

Looks like 4-2-1 to me.

Actually it's not...

There is supposed to be a section where the 4 goes into just 2 pipes then that section goes into the 1.

This picture has nothing to do with the Cobalts but this is what a 4-2-1 design header looks like:

 

You can clearly see Vibrant is 4-2-1, except the 2 pipe section isn't long, and it doesn't have to be. Does anyone have some good specs on these headers? I heard Vibrant is 3"???? What is Weapon R made of? Primary sizes on both.

 

Weapon-R Header is T304 Stainless Steel

and since you say that Vibrant and both Weapon-R are 4-2-1 design...tell me if this looks anything like Vibrants design...



What you're looking at on the Vibrant picture was it going into 1 single section. The point of a 4-2-1 design is to have it be 3 seperate pieces or sections so the exhaust flow breaks down smoother.

So the Vibrant is 4-1, the Weapon-R is 4-2-1.

FYI: I had the 4-2-1 on my Sunfire which was a L61...the same one I posted here and after a couple years of having that header, it did start to rust. By time I took it off to do the turbo setup, I don't think I would want to sell it to anyone but I didn't see any physical holes.

That's a type-o

I personally talk to scott and I can ask him myself.

Like I said, I am judging the pictures, it's a 4-1 design.

 

I'd like to have this settled because every I go it says 4-2-1 and it looks like a 4-2-1 to me. The two pipe section does not have to be long to make it a 4-2-1, it just has to be done in such a way to equal out exhaust gas pressures to give a smooth exhaust flow.

 

Then you show me a picture of a 4-1 design...

 

 

MEGA ROFL!

Dude, your "2" section is it going all into each other. It's still apart of the 4 design...it's no matter what TWO pieces!

Ok...question...so what do you think this is?

 

A side shot of the header you are showing would help but thats a 4-1 from what I can see.

 

So how is that any different than the Vibrant header?

 

Because the Vibrant tubes come together. Look closely, you'll see it.

I'm really sick of arguing about the 4-2-1 thing. I just want some general opinions about construction the specs of the tubing.

 

I think I give up...

 

a long tube race header is only good for top end power. a quality mid length 4-2-1style with smaller primarys is the best for almost everyone snce you dont lose low end you gain midrange and top end power just not as much as the full lenght race headers

long tube 4-1 race header big primarys bigger collectors

shorty headers 4-1 style small primarys big collector

4-2-1 style very common street strip made for versatility (sp?)

 

You crack me up Adam. You don't even own a Cobalt

 

I gotta get in on this.

The Vibrant header is a 4-1.

Also, long tubes may look pretty and may create more power overall, but a shorty header is gonna net you more power where you really need it, aka the low-mid power band. I used to want a long tube header simply for higher power #'s, but I realized that I won't really need it as opposed to the power my CA header creates. (more usualble power). Get the long tube header if you plan on taking your car to the autobahn......it'll work wonders there. I guess either way, an aftermarket header is better than the stock manifold, but this was just my 2 cents.

 

i think vibrant is kinda stretching the 4-2-1 ... looks like they run 2 pipes into each other jus before they run all 4 together ..maybe call it a 4-2-1 cheater?

 

4-2-1 is great for bottom end torque and some higher horsepower increase but in the top end you can not surpass a 4-1!
