Need Advice on header and Downpipe
 

Alright ive been thinking about The header with downpipe package from zzp

http://www.zzperformance.com/cobalt_...b9f6113f864804

any advice on a different header with down pipe??

Why are there so many choices?? lol

and if i go without the cat that will probably void my whole warranty correct???

it also says 15-35 horsepower can i say bull shit???? or are they really correct??

any advice is greatly appreciated

i currently have gm stage 2
bkr7e plugs and
a injen cai

15 horspower max maybe for the zzp. If you dont have a cat you wont be able to pass emissions and you will have a check engine light on all the time unless you turn it off with hptuners. As for the warranty it will only void the warranty for you exhaust nothing else.

The ZZP dp sounds like shit... and we've had fitment/quality issues with the header..
don't know about the rest of you guys but I"m goin cobalt-addiction stuff all the way... btw I saw their new header friday.... looks good and much better collector than the ZZP (actually smooth transitions and not partially block by the collector flange) and it gonna be around the same price if not cheaper

The zzp header fits fine. There have been numerous people on here who also said the cobalt addiction header sounds like shit. Its the high flow cat.

well then lol ill be checking into the one on cobalt addiction as soon as i can get the damn flash player to download

any others vouch for zzp or the cobalt addiction one??

ummm... the cobalt addiction header won't be released til the end of the week so how can you say it sounds like shit... first one is goin in tonight for testing.....

My bad I didnt mean header it was supposed to be downpipe. See how it says hi flow cat.

I say you get the gm performance header. Its proven. It fits good and its good quality.

hmm.. I have the c/a 3" with high flow car and it sounded alot better than my friends with the ZZP... plus his just snapped at the flange (flexpipe broke) after a about a month... c/a uses a braided flex pipe.... had mine for a while no probs and the car sounds mean as a mutha

I have the zzp header-downpipe and it fits fine. Ive put over 400 miles on it and its perfectly fine. Here is a pic. Dont get all upset because people are actually thinking about going with something different then Cobalt-addiction. :lol: My downpipe sounded like shit in the beginning but I think i had a leak. It got tightened the bolts and it was fine.

dude I"m not upset... I 'm just tellin from my experience... but did you look in the collector.,.. the last one I saw looked like crap...
anybody can run what they want.... I'm here to go faster and try to help others out... don't want my advice/opinion/... don't have to take it.. not forcing ya.
I did warn you about the header fitment when you got your first one didn't I... not trying to start problems..

They fixed the mistake, yea it should of not happened in the first place but oh well. Theres also the new intense header and the Gm Performance header out there. For downpipes I think there is one made by CTI, zzp, Cobalt addiction and i feel im leaving one out.

i also havent heard anything bad about our DP or heard anyone say it sounds bad,....

dezod has one too....

If i was you yellow ss i would try the new intense header. They usually make quality crap. And they dyno there product to give you a hp increase reading. If your gonna go catless you dont have to worry about the Dp sounding like crap either just get it from who ever you want.

sorry for the thread hijack.... I"m done

so is the downpipe the one that gets the most hp???

cuz when i talked to gm about there header he said maybe a 3hp increase

and im pretty sure gm doesnt make the best header lol

does it make any difference what exaust im gettting?

CTI FTW. nuf said.

Ya im done also. The downpipe has a big dent where the 02 sensor goes in so its the part that restricts flow the most.

+2!:twothumbs

no problem you always have good advice and to tell you the truth even though i could call it a hijack with u guys arguing just made me learn more without having to ask questions lol

We werent arguing, we were debating aggresively :lol: Its all in good fun, there are no hard feelings.

well with ur debate im still in the middle lol ill see what others have to offer like the intense or balt addiction

but like i said before the type (or size of exaust) doesnt affect the header and downpipe does it???

+3!:twothumbs I think out of all the headers out there, CTI is the most worth it in my opinion. I've already ordered mine, and I will know more when I get it, but I did a ton of research on the available header and downpipes. The CTI should produce the most power and torque, and there haven't been ANY complaints that I've seen from anyone who has it.:)

I"ve heard good things... just outta my price range so I'm goin with the c/a setup... plus after all the help they've given me and how good everything I got from them was... I stay with what works... BTW hitting the dyno maybe next week and def on oct 7th.... I'll have some numbers up soon (come on 300whp+)
