I definately wouldn't go with 5", way too many compliants about noise/drone. I also can not imagine why anybody would spend more than $70 on Genos muffler elimination kit when doing exhaust mods. Anything more is just wasted money in my book. The M. E. kit improves sound, flow, and lowers EGTs slightly with barely any interior sound increase, but a nice RIP on the outside.
the 5" drone is less than the 4" sys. I have had them both!
Good Luck
Thanks for the help I think I'll go with Brian Howell's Diesel Performance Products, Parts, BD & Cummins Diesel Performance. The 4" turbo back exhaust made by Diamond Eye. Thanks for the input.![]()
