There are other good options for intakes that cost quite a bit less, as long as your warrenty is expired...lol. They also can often be found used. I have an AFE I plan to install when my warrenty expires. Only cost $200.
The car will sound very good with just the exhaust, even better with both. If you search, you should be able to find sound clips with the exhaust only, and with the exhaust and the intake.
