This is for the people who just took delivery of there Vibrant header. I did a search and really couldn't find what I was looking for so I posted this. If there is a thread somewhere please don't flame my ass for not looking good enough. I am after all in Iraq and only have 30 minutes every few days to search for things.

1) How was the install? Did everything mate up like it's surposed to? or did you bring it to a exhaust shop?
2) Any dyno numbers yet?
3) What's the average supporting mods most have with it?(Catback, stage kits, ect.)
4) Did you get a CEL?
5) How does it sound and feel?

any help would be great. I've been ordering parts since I got here and all I need now is a quilty header.

I don't think anyone actually has one of these installed yet.

Little tip, if you plan on mating this with the Vibrant catback, I would take it to a muffler shop and have them chop the flanges off both and re-weld 3" ends onto it. Both the header and catback drop to 2.5" at the collector so that it could be bolted up with the stock system.

No point in trying to have 3" all the way back and have it dropping to 2.5".

 

so the collector is only 2.5 or do you mean the flange before the resonator?

 

One the header, it drops to 2.5" right before the flange on the end of the DP part. The header is actually 3", sorry for confusion. Its only like this so it can bolt up to the stock exhaust. Any muffler shop should be able to hack it and weld it to make a true 3".

 

sorry sent you a pm already, what about the exhaust the does it start at 3" or 2.5 so you can bolt it up to the stock header?

 

I just got my vibrant installed.....after driving it for 100km/or 60miles....my CEL come up....

Anyone know why this happend?

 

I heard a few people got CEL's but not sure whats causing it, i had mine for 5 months without any CEL's

 

When you instelled it did u disconect the battery for 30min or not

i did not do that, i was just thinking that it could help ... since they recommend doing it when instaling an intake

Thanks

 

i got a CEL too. it also runs the motor lean i would get the car tuned ASAP. i had it installed by a shop it looked like a pain in the ass to do.

 

1) Install wasn't bad after getting out the factory stripped Manifold to Down pipe bolts out!
2) I got 7 1/2 Hp & 18 wtq
3) I got it with the GMPP Sport it hooks up to stock or aftermarket!
4)NO
5) Love it & I put up a thread during Christmas of Vid & Dyno Numbers!

the cel is caused by the cat. if you don't have a code now. you will. give it time.

 

So you are saying drive it like this with CEL and it will go away after the car learns on it or?

Thank you

 

no you need to get it tuned like i did. you can unplug the battery but the light will just come back on.

 

You got 18wtq from the vibrant header and DP???? whats your mods, thats crazy the amount of tq you picked up

 

The Vibrant my friend got was 2.5, not 3. Install wasn't bad minus cutting the heater core pipe coming out of the block that it was hitting. I'll search and get a link to what we had to do.

my vibrant did not have to be cut at all eather did my car. But the header and downpipe combo was for a ion redline and it still fit on my cobalt lol yea i bought it out of someones trunk for cheep hehehe

 

I disconnected the battery for the length of the install

 

Is there anything like a switch..fuse...or somthin that i can plug out so that CEL dose not appear...on the dashboard

Thank u

 

No there is no fuse you can pull. Just find a local person with HPTUNERS and get them to disable the code for you.

 

k .... sounds good

if the car goes dead or somthing and i bring it back to gm will they know that someone played hp tuners with my car or no?

thanks

 

I'm pretty sure if you disable a code they would have no idea. Good luck man.

 

have any of your car's mileage gone lower after u added the header?
