Hello,

I have just got a 2013 2LS, and was wondering what I can do to improve it performance wise without voiding any warranties, any suggestions would be great!

Thanks in advance.

Welcome! Most parts will not void the entire warranty. For example, if you r radio stops working, they cannot blame it on the cold air intake you might have. However, if you blow your engine, they may not honor the warranty due to the supercharger and nitrous that you might also have.

Are there any cold air intakes or exhaust systems you can suggest?

Ask 20 people and you will get 20 answers on that one. For the cold air intake, pick the one that fits your style and budget. For the exhaust, pick the one that fits your desired sound and budget. See people's sigs and ask them how they like their system. Look for sound clips on manufacturer sites and YouTube. Etc.

There are claims that some make tons more power than others, but those are usually calculations or edge cases.

Okay.. Well thanks I'll look around and see what I like.

Are there any manufactures that stick out more than others? (like good manufactuors, bad ones..) your opinion on some of them?

Borla and Corsa always come to mind with me.

I have been looking around and I found an exhaust system that I like.. What I'm wondering now is about the cold air intake. Does it also affect the sound of the vehicle, if so, how much? and are there any that you personally like? (I'm pretty much brand new at this, and don't know much at all about cars)

I it's an automatic, "stall it" a 36k 2.5str is the ticket
