Hey guys need some help I want to buy and CIA and a new exhaust which ones are the best ones to buy? and the best sounding for the exhaust thanks a bunch guys TTYL

 

Not sounding rude but an intake is an intake and an exhaust system is nothing but slightly bigger piping to help unrestrict exhaust flow. It doesn't necessarily matter who you go to.

Also, there is no such thing as a "best" exhaust or intake, it's all personal preference. You'll learn this about modifying that not one thing is the "best" option for every person.

So basically, pick one and enjoy cause it'll be just like every other intake & exhaust system.

 

FYI: If you're getting an exhaust system upgrade, make sure you get a 2 1/4" exhaust system and nothing bigger.

 

what r you talking about! he NEEDS to get the biggest exhaust that he can get for his cobalt!

 

why not? i was gonna bum an ss/sc exhaust from a guy i know when he gets a catback, but i thought 2.5 was the highest you should go.

 

fixed the typos in your title. don't members double check for spelling errors before they hit submit?

 

Dont always listen to everything these people tell you. My custom made Manifold back exhaust is 2 3/4 inchs with teh stock cat stock resonator, and a Magnaflow Glasspack and I am registering way higher hp/torque gains on my Dyno from sunday then even the Corsa exhaust gives. But I do ahve some slight intake modifications and I am registering about teh same intake flow as someone with a Ram air setup would. Just remember the more air coming into the engine the more air trying to go out so exhaust is proportional to teh ammount of intake on your engine. If you are running stock intake and stock head tehn 2.5 is plenty for you though. If you are gonna run Nitrous, boost, or ram air intake I highly suggest 2 3/4 to 3 inch exhaust....

 

GMPP exhaust and Injen CAI for me

 

id go witht he inejn CAI and the gmpp exhaust

 

I was talking from experience. My 2 1/2" exhaust was too big and you could feel it. It would take too long for exhaust velocity to build up, even with cams and a ported head.

But you guys do what you want, it's your cars.

 

from experience the fujita intake throws codes and the corsa sport catback is too loud got pulled over for it but thats wit the ss s/c model idk bout ur car

 

the corsa sport cat back is quieter than i thought it would be. it hac a nice low rumble at low rpms and its only loud at W O T but i also have the WR intake

 

Hey thanks for the input guys

 

You're welcome.
