Purchased the GENO's muffler elimination and have driven 1340 miles and the average MPG increased by 1.0 MPG average (calculated). Just had the highest MPG of 19.98 for a 311 mile trip with speeds through small towns of 35-45 and highway to 75. Did not notice any increase in sound. Very happy with this mod since the price of diesel is up to $3.90 - $4.00 in my area.

I just did the same thing that savage.basher did. All I have is a 4" pipe from the turbo back. No muffler or cat. It is kind of loud, not annoying by any means. I just did it yesterday, and haven't noticed any loss or gain in performance, but my EGTs are lower.
