I order my CA stainless steel headers a couple days ago and im so excited for them. But heres the question...as far as downpipes are concerned, which do i get? I was thinking about getting the DownPIPE without cat converter (2.5") from cobalt-addiction.com but i really dont know which is best. Also does anyone have a quote for what an average installation costs for headers and downpipes are? Someone told me $200 but that seems high...maybe its just me.

 

install yourself, it's really not hard at all. if you don't feel confidant, have a local member show you how to do it. it's really as easy as unscrewing a few bolts, and then tightening a few bolts.

if you were local, i would help and wouldn't charge anything. maybe you could bring lunch or some beer

 

^^^What D4 said. I regret not doing my header by myself. I let a shop do it because I wanted it on before a dyno day that was fast approaching. In hindsight, I probably could have done just as good a job if not better, since I had a leak after they installed it.

 

wow, thats exactly why i want mine installed because of a dyno day on the 24th of Feb. I still havnt even ordered the downpipes yet because i dont know which to get...and im waiting for my pay check

 

having never installed one, or taken one off, i did it myself with the "help" of my little brother. if he wasn't "helping" probably would have taken about 2-3 hours. didn't run into any problems. if there's a leak, just tighten up the bolts, it's really that simple. all you need is a jack, and basic handtools.

 

If I were you, I would get the CA header on right away and then order the DP. This way, if you don't get the DP in time for the dyno day, you will at least have the header on. And if you get the DP in very close to the dyno day, it will be a much easier install than doing a header and DP.

I found out that my header was warped where it bolts to the head.


Don't forget jackstands.

 

downpipe takes about 20 minutes max from UNDER the car. first time i did mine when i had the 2.2, i tried getting the bolts from the engine bay. was an absolute BITCH. when i recently did my zzp header/dp combo, i got the downpipe off in literally 5 minutes from underneath with a breaker bar.

 

cool, headers on a cobalt, that got twin rotaries too!! sorry, just being a dick tonight

 

so, in light of all this, does anybody know which downpipes to get? I e-mailed kenny on cobalt-addiction but i havnt heard back.

 

i had the cobalt addiction 2.5" downpipe, i liked it. it will sound like **** without a cat though. imo, not worth the extremely minimal hp you will gain

 

bro serisouly get the header and downpipe and install them at the same time...trust me! rusted bolts are not fun to deal with...u ever get a new maf for ur car too? personally the 2.8 collector is a lil to big for our car thats y i have the older vs.

go with the 2.5 w/ cat from kenny..good downpipe.

 

get the catted dp the noise is not worth the 1-2 hp gain

 

i get my paycheck Wednesday so ill buy the new maf then...but thanks for the help man!

 

especially with you being in california, you don't want the catless dp.

 

hahaha that mite be bad..let me know when u get that maf put in..

 

alright man i will, ill probably deal with it this week, but steve isnt available so we cant actually put it in till next week, ill keep you updated tho

 

why are yall switching maf's

 

it got fried..by his intake...but def go with the c/a2.5 hf cat downpipe...ill be picking that up for my car soon too. i live like 10min away from c/a and they pretty much make all that stuff rite there..its made real well..keep me updated

 

So how much whp do u think i will gain from the header and downpipes? Ive guess around 12-15 but hoping like 20.

 

people are frying MAF's with intakes? really? i havent heard of it before

 

it can happen.

 

you can only get to bank 2 from the passenger side, so just be aware of that. you may have to drop the subframe and tilt the motor to the side a bit to gain access.

 

lol that is a smart ass remarck if i have ever heard one Jerry. but yeah we only have one header since we are only 4 babgers

 

i'm gona guys with an oiled filter too much oil is killing it

 

you mean header (there is only one)
