Hey guys, im looking to buy some preformance parts for my cobalt even tho its a lease . im looking to go GMPP just because with those i can trust my warrenty wont get voided.

So im looking to buy: Air intake
Preformance Exhaust
Exhaust Manifold

How much horsepower should these bump me up to? and what ones will give me the most bang for my buck?

 

I dont think GM makes a cold air intake for the 2.0L. But with the Manifold and exhaust, Id say between 15 and 20hp? Not to sure though.

 

Its for my 2.4 anyways, thanks alot for the quick response ++Rep

 

Thx. I think the GM Intake works for the 2.2 and 2.4s. Id say it would give you between 5-8 hp though. Get em all and go get dynod!!

 

I have alot of GM parts on my car and am very satisfied. Love the sound of the exhaust, but have not had it dyno just yet. I did a stock dyno and put down 208hp at the wheels, so once I find time to dyno I should be able to tell how much hp I gained from them at least.

 

I'd say with those parts on a 2.4 prolly more in the 10-15hp range... get a good tune and then it'll prolly be more like 20-25 hp! Get some 2.0 SS/SC injectors for even more powa!

 

2.4 or 2.0 i have 2.4 i got the gmpp intake which i wouldnt recomend. and i have the gmpp performance. which is great for about 10 or so hp. the intake is about 5 hp. not to bad so id say yes go with it.

2 things:

1) if it's a lease, why mod it? are you planning on keeping it? that's alot of money to spend for something you'll be giving back soon.

2) since you mentioned warranty, when you lease a car you're not allowed to do any modifications, doesn't matter if it's gm or not.

 

But if he mods the car now, and removes the performance parts when it comes time to return the car (if he decides on that) shouldnt he be okay?

 

i have those same modds and it felt like i got around 18-19 hp to the wheels, but i have a 2.4 , it just depends on the engine, and the 2.0 doesnt come with gmpp intake

 

Why wouldn't you reccommend the GMPP Intake?

 

Well i just leased it not even a month ago..so i got 3 years and 11 months to go, i dont plan to buy it out if GM releases a new Cobalt SS/SC around that time..but if they dont i mite end up buying it, also the parts i want arnt a huge amount of money...1000 tops? and most of it i can take off and reapply if i decide to trade it in

and with my lease i talked to my dealer and made it very clear that i want to mod it and he said yes you can do anything you want as long as u dont **** up the car were we cant fix it lol, hes a good friend of mine so im not worried about that.

Thanks for the respones guys, i think im going to buy the GMPP Exhaust /w manifold and get a K&N typhoon air intake if my dealer says thats ok, if not il go GMPP

Also are those 2.0 injectors called the stage 1 kit on GMPP's site? i was always wondering what people ment by 2.0 injectors can somone explan that to me

 

the stage 1 kit is for the supercharged modles only, and superchargers only come on 2.0 liter motors, not 2.2 or 2.4, now you could fit those injectors on 2.4 for more power but you will need a tune and will also void your warrenty, just stick to the cat-back, manifold and intake like i did.

and yes the K&N typhoon air intake will void your warrenty, put it this way, if you didnt buy it from the dealership , its gonna void your warrenty, engine wise. sucks i know

 

K&N Intake will not VOID your warranty no matter what anybody says. K&N will even back that statement 150%. What it will do is you will no longer have a warranty on your intake. If there is a problem, the dealer will have to prove that it is a direct result of your Intake which will be incredibly difficult if not impossible. If the guy is a buddy of yours I don't see him doing that either. If you want the K&N install it yourself (it isn't that hard) and when you need to bring it in... replace it with the stock airbox.

 

So should i got K&N or GMPP Intake??

 

I believe the consensus is Intake is Intake so it doesn't really matter. If you want it warrantied get the GMPP. If that doesn't matter to you, get whichever you think is nicer looking. the GMPP can be made to be functional (by cutting the hood with an offset scoop...not reccommended for lease - or - by getting an aftermarket hood which directs the air from a scoop into the intake). Personally I plan on getting the GMPP since it is a closed box and therefore will not be sucking as much hot air from inside the engine compartment and do plan on making it functional.

 

just get the gmpp, you'll keep your warrenty
its the same price as others
easy to install
replacement filter is just 30 bucks
all and all you dont have to worrie about changin it out to take it for warrrenty work.

 

I have the GMPP manifold and exhaust system, but i went with the injen intake because i wanted to go cold air instead of short ram....

 

talked to my dealer today and he said 500 for the mainifold installed and about 600 for the preformance exhaust installed, i think once i get some Overtime hours im going to get the manifold first followed by exhaust then intake later. thanks alot for the help guys

 

i wouldnt go too crazy with mods, those stock injectors cant handle too much, they pretty much come from the factory at 100% duty.U will be ok with just an intake but exaust and header might be pushing it im not intirely sure.

 

woah woah woah, i said $170 install for manifold and cat-back, you got ripped off

 

dude, you should get both installed for like 650. install it yourself and you will save even more! its not that hard... just some jack stands and a couple tools.

p.s. i read somewhere on here that gm is releasing performance injectors and tune for the 2.4......

 

the price i said inclued the manifold and installation

 

oh thats all said and done price....thats not too bad, i wish i woulda put the cat-back on myself because its all bolt on, no welding required

 

You do know they canceled the SS/SC, right?
