whats the best exhaust for my 06' 4.7?

 

On mine i went with the flowmaster 40s they sound great and gave me about 2 more mpg and more power over all.

 

magnaflow catback duals.....sound great....no drone.....nice tapered chrome tips.....split back

 

I am tired of typing it but I love my Gibson Super Truck on my HEMI.

 

Add a HIGH FLOW "Y" pipe going into a true single 3" system with. Get the high flow muffler of your choice. I have gibson headers and liked them allot. I installed them in less than 3 hours, and they look great. I did notice a performance gain with them BUT they where one of the last mods I added so by the time I swapped them the stock logs where a restriction.
