Oh yeah, a guy in the shop at our dealership installed dual exhaust and an intake system and he says its almost as quick as a 5.4 now. But the exhaust is almost too loud now, he has had it on for 8 months now and its kicked in alot now.

If you're looking for improved fuel economy, the K&N won't give you any and you probably won't notice too much from the exhaust. I had a k&N on my 5.4L and saw no improvement in FE or power. Just a lot of marketing bs..

A tune is your best bet for performance. An exhaust will help maximze the hp you can gain also
