dont flame me cuz i know its been covered 1000 times

but on a 2.2 which is better 2.25 inch piping or 2.5 inch piping

cuz im thinking of either the tsudo or megan

 

so why would you make a new post if you know its been covered 1000 times? here's some links i found by using search. others might not be so nice to you. i'd suggest using it next time.

so im guessing i should go with a 2.5, cuz i plan on doing other smaller mods like the 2.4 intake mani

will the megan bolt up to the 2.2 stock header/dp

 

don't do the 2.4 mani until you free up the rest of that exhaust. half-assing it isn't gonna get you the best performance, period. freeup the exhuast completely then do the intake w/ intake mani or do it the other way around.

 

so how does this sound, 1 3/4 headers, with 2.5 exit, to a 2.5 downpipe with cat with megan cat back

then do the CAI with the 2.4 intake mani?

 

nice...lol **** modding a 2.2 im jus going to save for an sti...its not enogh for me...my car is paid off and no sense n voiding the warranty by sc'n it or tc'n it...ima jus trade in for a car built for boost...

 

sounds like a good plan. you'll appreciate all the work.

 

blackmachine, i hope you have fun with your STI... cuz obviously your ***** aint big enough to have fun with..

nikebaseball.. i supercharged my car.. and i have the 2.25 vibrant. and the rest is 2.5.. lsj dp and and manifold.. it works.. but i mite upgrade to vibrant headrer and downpipe.

andblack machine.. congrats on your grand plan. i hope alot of people who dont have money to buy an sti look at your car. hell... i dont even think u got the money.. selling a 2.2 cobalt and going up about 20 grand extra to get an sti.. y didnt u get a supercharged balt again?

 

**** gettin an sti or any foreign car for that matter, SUPPORT THE AMERICAN ECONOMY FTMFW

 

2007 paid off already and you couldn't have gotten a better car when you picked up the balt? you cool.....................not.

 

haha, exactley

 

my man!! lol go ahead and buy a sti, your right u could probly get more power out of it, yea your baller statis would go up, but if u build a slow car and make it ***** out fast or even like 13's its still something u built.. plus for every JDM super car there is an american one there to kick its ass!!! WOOWOO

 

good call, he will get an sti and someone will still kick his ass in a cobalt

 

then after the cobalt kicks his ass, the driver of the cobalt need to get out and kick his ass for real for being a *******

 

Can i say something, I love my 2.2 turbo

 

can i say something, i love ur cobalt too
