ok so within a week or two i should be installing a header,dp, n exhaust on my car. i was jus wondering if any of u can give me some input on how hard it is, thing i should look out for, and ect.
also i was wondering if any of u can tell me how much of a increase i should be getting from this compared to stock. i also have an injen intake on my car. its 2010 2.2 lt

 

if i were you id upgrade to a 2.4 intake mani to free up flow and widden your powerband. and then a tune would pull it all together and make your car run a lot smoother. if you need a tune let me know. $250 shipped will save you $35 compared to buying direct from CAI or trifecta

 

You need to spam this everywhere huh?

 

Doesn't the 2010 have VVT?

 

09-10 have VVT

 

i beleive youre car has an LAP in in not L61

and if it is an LAP, it already has LE5 intake manifold

 

ding ding ding

 

also, you HAVE to get tuned when changing the header out because (i believe) all lap's have sai...and youll throw codes and stuff unless tuned...

you could gain anywhere from 2-12 ish hp from changing, add a tune and look at another 10ish
really depends on what system is going in...if its all sized right and flows well expect higher numbers, if you went with too big or small of an exhaust you may make power in some areas of the power band but not others...
only way to tell for sure (because everyone will give you a different answer haha) is to strap it to a dyno and find out!

 

Exactly why I asked if 2010 was still the LAP.

 

yea i have a 2010 lap. i posted in the wrong section. so what this about the le5 and 2.4 intake manifold??


i already installed an intake and im pretty positive i dont have SAI. i had it on my old cobalt n i dont see it on my nee one. i have vibrant header n dp n corsa touring exhaust.
