performance packages for 07 6.7 Cummins
 

I would like some help selecting a total performance package for my 07 6.7 cummins. I would like a totally new exhaust that wouldn't be too loud. Also looking to improve mileage and performance... Don't want anything radical, just a good all around package that won't compromise long term reliability.
Thanks for any help,
