Muffler Delete

[04Powerstroke]

Will this give me better fuel mileage? I just pulled mine off and straight piped it. It's alot louder now but I am looking for mileage. Opinions? Btw, the system is a 4" magnaflow turbo back to duals.

Where did you get the delete pipe? I can find plenty of 4'' pipe around here at local muffler shops but NOONE can expand it.

My magnaflow came with 2 pipes, 1 for an extended cab, 1 for a crew cab/long box. I just took the extra piece and cut it to the lenth of the muffler. Took out the muffle and put the pipe back in.

My cat was gone when I installed the system. Now it is straight from the turbo to the tail pipes.
