Here is a picture of the Vibrant 4-2-1 Header. Everyone though it was a myth or that they would never come out with it. Well here it is. I should be receiving my first order of them shortly and I will have more pictures available when I get it in my hands. We are going to be having a group buy on these as you all have seen in our vendor forum.

 

YES, count me in!!

 

those look like a cery well piece. It probably has a 3" exit tho. Not good. Do you know i they are going to offer them in 2.5"

 

Any estimate on Price? Especially if there is a group buy?

 

Same here. I am worried the 3" is big. If i would buy that 3inch header and 2.5 downpipe and catback, would that be a bad ideal?

 

I should have the exact specs for you on pipe diameter and all of the by tmrw.

 

niceeeeeeeeeeeeeeeeee

 

Tom

What do you think about a GMPP manifold that I would bring to the machine shop to get bored and smooth out? Like make the manifold holes bigger and like smooth out?? I am just afraid of my dumb dealer down here and them being very afraid of aftermarket parts.

 

that looks ohhhh so nice!!!!

i cant waite for details..

no cat and 3in collecter for the win!!!

 

Its Scott but that is ok. If your worried about it I would talk to your dealership and ask them if it is going to be a problem. Some may say yes others may say no. You can always stick with the gmpp parts. Check out Crate Engine Depot they have aq great reputation, sell gm performance parts and most of the time you wont get any grief if you have GM parts on the car. Like I said though. Check with your dealer or the dealership that does the work on your car first.

 

Yeah i'll chek that out, and let you know!! And keep me posted if the header would work good with a 2.5 or even a 2.25 catback. I havent got a catback yet, but was planning either GMPP or magnaflow 2.5 or meagan 2.5.

 

I will let you know as soon as I can.

 

its a 2.5" outlet i have asked them before

 

Thanks for letting us know.

 

Looks like a decent piece but is that the 2nd O2 sensor bung before the cat Im seeing in the pic???

 

I would assume that is a wideband sensor location. I was able to get the pricing now so we can start working out the groupbuy stuff. Our normal everyday price is up on our site now.

From here on out the Group Buy ?s and pricing will be in our vendor section. I dont want to fill this thread with sales crap.

CPP Vendor Section

 

can we get more detail?

what size is the collecter?...is there a 3in option?

do we have to get the stupid cat or can i get JUST the header...??

 

It comes as one unit. As far as I know at this time I cannot get it broken apart. I will contact them tmrw and find out if we can possibly order them with or without the b-pipe

 

so this header will fit into my corsa exhaust no problem right?

 

I do not see why it wouldnt.

 

well it sais that it fits into the stock exhaust which would be the part that is 2.5 inchs but then it sais this would go perfectly with our 3 inch exhaust so idk what is up with that

 

Sorry Im trying to do the best I can at answering your ?s. Its late at night and I have no way of getting any more technical information. I have my employees up working on pricing for the groupbuy. Thats going to cost me some pizza and beer if we dont get it figured out soon. I am composing a list of ?s to ask them for tmrw. If you guy want me to add anything to it besides what in the thread let it rip.

 

The part necks to 2.5" to mate to stock cat back then if u get their cat back it goes from 2.5" at the header connection to 3"...its not a true 3" and i was pretty upset with them after hearing that after waiting soo long.
