My current setup is Stg 2 with K&N intake ZZP header with 3" downpipe but factory exhaust...i had a custom cat back but too loud so i am waiting for a bolt up...but my ? is i have ordered colder plugs (NGK) and have a 2.8" pulley so after these installs where should i go from there? any advice at all...thanks a lot =Dustin=

 

are you askin what kind of exhaust should u go for that will give you the best gains??

 

I would suggest getting either a 2.9 pulley or if you want to stay with the 2.8 get 60lbs injectors. Your 42's wont like the 2.8.

 

I think what he is asking is what mod other than exhaust should he do next. Well I would suggest, either the dual pass option b, or a bigger heat exchanger, matter or fact do both!

 

a bigger heat exchanger wont net you any gains it will just help you cool, unless you are at a 2.6 pulley or even a 2.7 pulley it wont be beneficial to you....

I would say get a exhaust, better tune,

 

Tune, traction, cooling, and internals......

 

ok thanks...now the factory exhaust is 2.5" correct? if so what 2.5" exhaust is best to get?

Yeah basically i would like to know what would my best choices be to work with what i am having installed without getting too crazy? I want to be around 260 whp

 

no factory exhaust is 2.5 and tapers down close to the rear axle to 2.25 making it really restrictive... If i were you i would invest in a corsa since that is a true 2.5 exhaust all the way.... or even get the gmpp which is just like the stock one but not as restrictive and alot better sounding

corsa exhaust, and put a 2.9 with a better tune and youll be pushing 260

 

So if i get tuned and go in for warranty will i have to get re-flashed for the dealership not to know?

 

if ur wanting 260 hp the 2.9 wont be pushing it... It will not cause a problem or bad idles, or your car to shut down so i would just do that if you feel better you can just change the pulley when you go into the dealer but no they wont suspect anything...You wont even have to change your tune to put on the 2.9 that is considering you have the stage 2 tune... but if you want the most out of your car get the tune!!!!

Now i would also invest in a better CAI as in the 3 inch not jbp but the other one that their selling looks like the best intake on the market right now alot better than K&N, airbox mod, and all the other ones

 

Dealer wont know if you have been tuned or not.

 

your 100% sure? ok well i already have the cobalt addictions Stg 2 2.79" pulley so should i sell that and get a 2.9? ill settle shy of 260

 

you heard my exhaust and my brothers.... he has the zzp long tube header with ark exhaust and I have zzp shorty header with the catless dp and megan cat back if u dont remember... reply your thoughts for the thread starter

 

yes 100% sure, i mean unless they really look over your car... if you dont wanna risk nething i would just buy the 2.9, the exhaust and thats it done worry bout the tune.... Youll be at 260

 

You are talking about a totally different stage 2 then what I was thinking about. I thought that you were taking about the GM stage 2. What size injectors come with that kit?

Both car sound very good.

 

if your mistaken....were talking about the GM canned stage 2 tune with the 42lb injectors with the 3.1 pulley pushing 15lbs of boost...

u take the 2.9 pulley on the warrantied tune and youll be straight

Yeah i am talking about GM stage 2. So i can keep the GM stage 2 tune with the 2.9 and get exhaust and ill be 260 or close?

 

Yes!!!!!

 

Ok well i will just get the corsa catback and the 2.9" pulley...do i need the 60# injectors for the 2.9 or will the GM 42# be effecient? (spell check)

 

k thanks for your time

while im here any suggested traction mods or problems with this much power i should be aware of?

 

I am sorry I misread his post. 2fastss is correct but if you want to take full advantage of the 2.9 you must be tuned for it. Dealerships will not know that you are tuned if you get tuned. The only why that they know something is different is if the pulley looks different.

 

2.9 doesn't need 60's but it also wont hurt. If you get 60's you will need a tune.

 

oh ok i was under the impression the computer they hook up your pcm to would show everything tampered with but i believe you lol

 

if the louder the car is, the faster it is. my car is a ******* cruise missle.

 

lol definetely not the case i promise...i had an eclipse that was 18s hahahaha automatic of course but i didnt run it but once and it was louder than a rock concert...had to be breaking the DB law
