Hi was hoping to get some input. I am changing out the exhaust on 07 Dodge Ram 3500 6.7. Changing to 5". Was wondering if anyone has made same upgrade and if so did you encounter in issues along the way that might help me in the installation. Any 02 sensor issues etc..? I am looking at the Diamond Eye Exhaust System with the Dynomax Exhaust Tip. Any tips or suggestions? I appreciate any input!
