I finally got my stack put on my truck and i believe it improved my fuel mileage by 6 mpg. I wish i would have done this earlier I love it. now i want to do more mods.

 

6 mpg come on now. But if it did please let me know what you did. I have 4'' from turbo back into a box and then 2 6'' stacks. My mileage went down because i like to hear the stacks talk when on the skinny pedal. Yours look good comptz good job.

 

Thanks. I dont know what did the lileage increase but i also had a golfcart in the bed also. My system is a 3 inch straight pipe to a elbow straight through the bed to a 3in to 4in adapter then a 4 inch pipe from that to the top then a rain cap.

 

My milage increased also. It was due to me trying to be QUIET as it is a straight pipe. It baby it alot more trying not to gain police attention.

 

That would prolly be it.

 

IMO way to small and way to far away from the cab.Ezra

 

the reason its to far back is i didn't want to cut the crossmember and i dont have the s pipe that i need to put it up in the front of the bed.

 

The distance away from the cab isn't that bad, but I think a 5" black stack would look cooler for sure. Hey, either way a single stack is awesome and eventually it's what I plan to do (but not as easy to mount when you have a flatbed though).

 

looks like a tractor, I like it, but i think if it was bigger, it would look cooler.
