The reply I received via e-mail... The manual infers the warranty might be voided by this kind of thing, but it says you can't even change the tires!

Thanks for the response. We build high performance, aftermarket exhaust systems and headers for motor vehicles. Our products provide performance gains, an increase in fuel economy and sound enhancements. We take a great deal of pride in the sound characteristics of out exhaust systems and I assure you that our exhaust is not loud and is especially quiet inside the cabin. The sound enhancements are of a tonal nature rather than a decibel level. The sound will differ from your stock exhaust because it has a distinctly different tone (deeper and throatier), not because it's louder.
It will not void your warranty. Click below. http://www.impalaclub.com/naisso/magmoss.htm

Basically, there are no drawbacks to Borla products. Only improvements over stock.
We use the best materials, provide the most power, have the most refined sound and offer a million mile warranty.
What is the full title of the model you have?
Please let me know if you are interested or if I can answer any more questions for you,
