Last week I installed a Pro Force Exhaust on my 2007 5.7 DC 4x4. I was happy with the results and found the installation very simple.
This morning I installed a Volant CAI. The installation is also fairly simple but their instructions leave room for improvement.
My truck definitely sounds better. The Pro Force has a nice mellow sound and when I put my foot down the intake combines with the exhaust and it really is music to the ears.
And while I have no way to measure it the pick up feels better.
Next on the list are some nice rims...
