Thinking of going with dual exhaust on my 2005 Ram 4.7 anything i need to change or be aware of if i go that route.

 

True duals or a catback system?

 

true duals

 

keeping the cats though just true dual with cats

 

As long as you are keeping the cats and not doing anything with the O2 sensors, it will be fine as far as driveability.

 

ok thanks for the reply

 

I seem to recall the 4.7 ideally needs a pipe size that normally isn't in a mandrel bent cat back system. Like 2 1/4 or something. That's part of the reason I went with a 3inch single. But, I expect duals would sound a bit nicer.

 

I have a 3inch single catback, no issues, but one thin I did do was upgrade my y-pipe to a slightly larger one.noticed a lot more low end torque, and the get up and go on the highway improved
