I have an 06 cobalt ss/sc with 70,000miles. The only performance upgrade I have it the stage 2 wich was money well spet. This car is my daily driver, and has to be reliebile(sp). I drive 100 miles a day back and forth to work, so it is all highway speeds (70-90). Im looking for some more performance, just dont know what to do next. I would like to get around 260hp, is this much hp still a daily highway driver. Thanxs guys.

 

damn youve got some miles on that thing!!! I would say you should do some cooling mods get a tune and change the injectors to 60's and get a smaller pulley and tune...you could do the headers, downpipe, and cat back thng but im sure all that noise would be annoying since you drive so much...

 

yea I avrange around 800 miles weekly. I have heard the #4 cyilder melts down with the 60# injectors.

 

um. no.

header back exhaust is what i would do.

 

^ X2.

 

will that make a noticeible diffrance, also what brand

 

a full exhaust including header downpipe and catback would net you probably 20-25whp.
so yes it will be noticable.
as far as which to buy....i suggest you start lookin around and reading.
everyone has their own opinions on which gives the best power....sound....etc.

personally my suggestion would be the ZZP midlength + downpipe group buy thats on right now....coupled up with your choice of catback.

 

Header back exhaust, and an intake will help ya out alot! My car makes 262 hp and drive it everyday! So no you are fine with it!

 

i have a Brand New ZZP Header Downpipe with high flow magnaflow cat
combo never used, that should help you on your way there.

 

I would do a heat exchanger and exhaust.

 

headerback exhaust for sure.

 

sound good thanks for the help. What is the best part to stop the wheel hop. I see there is a few things I can do. Do the motor mounts or the dampner
