I was wondering what would be the best bang for my buck the GMPP Header($225 shipped) or C/A Header?(3-4 weeks according to kenny till the revised one coems out for us 2.2L $250ish + shipping) currently i have a Injen intake and dc sports catback exhast. i plan on getting a C/A 2.5 catted downpipe which will have a 2.25 end to connect to my catback. let me know guys opinions needed

 

Have you considered the Armour Coated Pacesetter? They're the only cheap, long tube headers. Will run you the same price, about.

 

well ill be doing the install in about 30 degree weather in my own garage and i would like to be able to switch back and forth if needed so bolt on is best for me. altho i didnt think about those.

 

Since you've already gone aftermarket go with Cobalt Addiction's piece.

 

if you're looking for performance the c/a is the way to go...

 

but i will have to wait 3+ weeks before the release the new one for the 2.2L im not looking to go all out on my car. just an upgrade from my stock parts.

 

i vote C/A!

 

im in the same boat as you Mkulrey... also when are they coming out with the new ones from C/A... and whats changed?

 

it's worth the wait...

 

its definately worth the wait. i bought the original CA header and had to send it back..but i was more than satisfied with the design and quality of the CA header. i am waiting for the new CA header as well as some other members on here. go with the CA header. you wont be dissapointed. i am also going with the CA downpipe with cat. i will have CA headers and downpipe w/cat and a magnaflow catback.

 

Not knocking C-A or the 2.2, but isn't that a bit more free flowing than you really need for that motor. Unless you are looking to go FI or Nitrous, I really don't think you will like the result of the 4-1 especially with that large of tubing.

You would probably get more usable power from the GMPP Manifold if you don't plan on anything more than 250 whp. 4-2-1 headers are designed to promote mid range power/torque which is where the 2.2 shines.

 

that motor is designed for good flow...which the stock everything is so restrictive. opening it up with there header and a downpipe..will def get some nice gains..u add on a catback now ur talkin bout a whole difference compared to stock. when i had just a intake on my car i totally felt the difference. i havent been down the CA shop in awhile. if i get down this weekend ill ask kenny for u guys cuz i have alot of questions to ask him bout my new car...but yeah def C/A header..with a 2.5 highflow DP of theres and a GMPP exhaust..good setup.

 

so the GMPP header and C/A 2.5DP W/cat wouldnt be a good setup? like i said i already have dc sport catback exhaust i dont plan on doing anything beyond this setup.

 

gmpp manifold is fine for your setup.
i have it on my car with the c/a 2.5 dp with cat and gmpp sport exhaust.
also, if i felt a nice increase in acceleration by adding the gmpp manifold.

 

I'm gonna jack this thread. I was going to start a new one, but since my question is along the same lines - I'll ask here.


If money weren't an option, which route would you go for your 2.0 SS S/C?

Hahn Racecraft Shorty Header
Hahn Racecraft High Flow Cat Downpipe
Hahn Racecraft Cat back exhaust

or

Vibrant 4-2-1 Header w/ high flow cat
Hahn Racecraft Cat back exhaust

Neither have given any numbers or results. I haven't heard any clips of the Vibrant. The Hahn Header looks to be of amazing quality and design. The welds and bends are simply amazing.

Can someone tell me which way they'd go and why they would go that route.

 

personally. i wouldnt do either. ive see so many ss/sc around by me with some good stuff on wrech alot of cars. what i will be doing when i get my 07 ss/sc in will be. C/A header, CA 3" High flow DP, GMP Performance/Sport Exhaust. the design on the CA header for the 2.0 is a awesome design just like the 2.2's and they have a awesome downpipe...there my deal.

 

so the 4-2-1 CA header wont be as good as the GM one? thats why i was thining about getting the one CA they are selling NOW so then it isn't a 3 in collector? i have a pace-setter car back and was ganna go woth the ca manifold and high flow cat along with my injen CAI, so the GM one should work out better? im looking for the top end since it seems to go flat around 5,300 and was thinking that opening it up should do the trick?

 

the c/a header gave a stock 2.4 10whp. so it def would give a 2.2 some good gains. and yes the high flow dp would give possibly 8-10 as well. these cars respong well to a good downpipe. if u want to talk to c/a email kenny. just go to their site.

 

Personally I would take a 4-2-1 over the 4-1 if you don't plan on running more than 7,500RPM. A 4-2-1 promotes mid range torque which is more useable and benneficial than high RPM torque. 4-1 headers are best for high RPM torque. If you upgrade you valvetrain to handle 8,000-9,000 RPM then you would want to get the 4-1 to take advantage of the top end.

As for the cat back, I would probably go with the Vibrant 3" with the Magnaflow muffler. Blown 4-banger has the Pacesetter 4-1 header with a custom catless 3" Magnaflow exhaust. It sounds awesome, if you are into loud exhaust. He does suffer a lack of bottom end do to how free flowing the exhaust is.

 

has anybody actually had experience with the both of them? it seems like what an individual has.. is always the best.. just curious

 

FYI: CA header is garbage. Look at it. Are you buying it to last or just to give you short term HP?

 

I agree with you on this one. The GMPP is ample for the SC 2.0, which is moving more air than the 2.2 will ever push. I have the GMPP on my 2.2 LS and it is more than satisfactory. Also GM won't make an argument over the warranty should that ever become an issue. A header is overkill, but on the other hand, can't beat the look and sound difference if that's important to the owner too.
