thinking about putting them in. main question is are they worth it? what hp and mpg gains could i see and how much does this project cost roughly? i have an 02 2500hd 6.0....and after putting 33s on im looking for anyway to get more mpg

 

nobody has anything to say or any experience with this?

 

Bout 10hp and maybe 1mpg. Not really worth it for the mpg aspect but it cleans up the engine bay and you don't sound like a jet on takeoff
