Anyone on here running this header I was thinking of getting one their gains from it seem impressive just seeing what people that have it think about it.
Thanks

 

Do not get! horriable design and reduced power on a TVS, there is a proven dyno sheet

 

Does no one search?

 

unfortunately no

 

actually I did search but thanks for the free bump

 

Isn't he doing his research by asking on peoples opinions? I think so

 

That header is a complete TURD! lol. A lot of people have been ditching theirs and getting another header. You will actually LOSE power with the JBP. I think it sounds like ass too. Common sense tells you it won't flow worth a ****. The Vibrant header has been dyno proven as one of the best headers for the LSJ Cobalts. I just scored a used one and it is a very well made header. It is made from 304 stainless and even after being on another car for 2 years, it still has some shine to it. I'm sure it would polish right up with minimal effort, but I can't be bothered.

 

Sounds amazing, flows like poo. One member dyno'd at ~312whp on stock header w/TVS, swapped in the JBP header and dyno'd ~260whp. that's an incredible decrease, not to mention all the timing he had to pull to keep his motor from self destruction.

 

Thanks I thought so to!
Anyways thanks for the help I have heard more than enough

 

but it self destructed anyways.

 

I have one on my 2007 ls 2.2 manual with a supercharger setup and i like it. people say it sucks but i cant say anything bad about it.

 

garbage. spend your money on ANY other brand than JBP. hell make one out of monster cans and itll flow better

 

Mine kicks ass, sounds great, makes great power and looks exotic.

 

It's a waste of money.... PERIOD... sounds good flows like dog poooopie!

 

have a dyno sheet for that?

 

you guys saying it makes power, did ya'll modify your headers at all? Got any dyno proof to show gains? Track visits to show gains?

 

if you add a flux capacitor at the end of the collector itll make your car go mach 3.5 till redline

 

I know for a fact that if you fix the flaw in this header, it will perform pretty nicely. But I doubt most of these guys, if any, have done that.

 

Not that I would ever run it... but what is its "Fixable" problem?

 

Yes, I have dyno sheets if your talking to me, I have access to both our dyno's, a mustang and dynojet, does it make gains yep, do I need to share my findings with anyone on here, nope as most are internet engineers with some excuse for anything they dont like. I have also been called out on it and shared the information in an email to ******* , funny that the information did not match his and it never made it on here. It does make power straight out of the box, and what it does for your torque curve is amazing. However, I will admit that some recieved different quality headers. None of the primaries on my header touch anywhere, others peoples do.
As for making more power than out of the box, yes you can do it,
I blended the intake flange and then redid the collector for better scavenging, that alone was a bitch so I was not about to extend the primaries when it is working very well for me. Doing the collector really extended my torque curve.

Would I buy another from JBP, no. Why not, due to the inconcistency of work on the last batch of headers and the major screw job on a forum member.

Two other guys local to me run this header, I don't know what Omega dyno'd at but he has stated that he is very happy with it. The redline its on gained major torque throughout the curve and a little horsepower at peak over the stock manifold. Keep in mind his header was installed with a stock downpipe and stock cat back.
