5" Exhaust Questions

[TomGolden]

Ok, has anyone gone from a straight piped 4" system to a straight piped 5"? I have had my Pinnacle Performance (by Jerry Jardine) 4" system straight piped for a little over a year, and while I absolutely love the sound, the in cab drone makes me crazy sometimes. I have used a lot of the GSI SuperFoam inside the cab, ala GregL the Noise Nazi, and it helps some, but not as much as I'd like.



I want to know how the drone compares between 4" to 5" straight piped upgrades.



Me want 5" straight piped. mmmmm mmmmmmm
