Stop, dont be rude. Their site is obviously going to be bias. I can send ya to 500 sites that say their product does anything under the sun, but DON'T.

I asked for somebody, not jbp, to post some real results. I think the thing is a hunk of junk, and sounds like crap. Just my opinion

 

dude if you see the stock header you will notice that this one havent more resistance.
to be honest i like the sound of it, and i dont want to be rude but if you dont like it doesnt bother to flame it, just pass it over.
their are a lot of more header in the market that you can chose, i search and like this one and i buy it.

 

their site doesnt say how its different than a stock header.

Im sure its better, but just by looking at it, the logic just isnt there. the pipes are long, and contorted, it doesnt look like it works.

thats why he asked to see a dyno from someone unbiased.

 

The long, equal length primaries allow the exhaust gasses flow at an equal speed, so when they reach the collector, they merge without turbulence, further increasing the flow.

 

I installed mine last week and Im happy with it.

 

I have one on the DD with a complete, custom, 3" exhaust and the sound at 6,000 rpms is awesome.

 

Havn't dynoed yet... but my dyno wouldn't be accurate anyway due to the amount of modifications on my car.

The header improves flow... end of story, end of your question. It does it's job, and it sounds damn good doing it.

Here's your proof, I dropped 1 1/2 PSi upon installing this header. I barely push 16 psi on 2.5 piping, a ported blower, stock ss muffler, and this header, on a 2.7 pulley.

---------

Good luck purchasing this thing though... I waited 4 months for it, along w/ many other members. And if it fits the g5 gt it will fit the cobalt ss 2.4... same damn car, different bumpers and tail lights.

 

i bought mine like the first week of september and got it a week after and installed it last week. I didnt wait that long for it.

 

I had a friend who is a gm tech install mine along with a clutch and it only took him 5 hours to do both. It can be done and sounds awesome.

 

JBP currently have some headers in stock, you can pass by USD Autosports (an authorise dealer) to get them.

info@usdautosports.com

 

update: installed on 2.4 last month. still have hard cel code set... have reset numerous times but will come back on after awhile and stay on. i'm getting a code reader next week to see which code it is. i've installed an o2 sensor extender, but it doesn't work.

 

idk..................but i like this header.........

 

Can we still get the header at this price?

 

Is this still possible? If so I am all over this!!! I want this header!!!

 

I would be in too. Immediately

 

idk.....contact jbp......there good people....

 

i want in 2!!!

 

Hey guys,

CobaltSS.net members can always contact JBP directly through email or by phone, just mention you are a member and we will help you any way we can.

As for the headers we have 3 left. If any members would like one of the 3 I will extend the group buy pricing for the 3 remaining headers.

RyanRacer48's problem with one of our dealers, as far as I know, is an isolated incident. All of our dealers are reputable businesses that know the value of a customer.

With this said, I would like to extend my apologies to anyone who has been 'brushed off' by one of our dealers. So far this is the first time I have heard of something like this, I assure you it will be dealt with.

Thanks,
JBP

 

Damn, only if I still had my SC.

Are you guys tryin anything like this with the new SS/TC? I love the sound this header makes.

 

We dont have access to an SS/TC at the moment, but yes we would be willing to make one if we could get our hands on the car.

 

does everybody that bought this header like it???? I am being told not to put a longtube header with so many bends on my ss/sc because every bend acts as a restriction, i have been told to use a shorty header, i need to know what people think about this header since they have installed it! Thanks!

 

I couldnt tell you a difference with dyno but i am a fully built 2.2 and its definitely sounds meaner and deeper... felt like more power but hard to tell if its only 5whp more, ya know. like feeling the power gain from intake on a 2.2/2.4L

but turbo headers look like that, why would they have so many bends if they were restrictive? my friend with a civic with a log style manifold was droppin from 23psi to 14psi from 5500rpm to 8000rpm and with the tubular manifold he can hold 28psi all day long

 

I would be willing to help but with me living in ohio and going to college and all I am kinda busy

 

I don't know im just trying to get all the information!

 

Think about this......it makes a Cobalt sound like a WRX.......why does a WRX sound the way it does?
