Thanks for the info on the FTE. I have read about them in some research I have done lately trying to quiet mine down a bit. I just don't have an extra 12" to put in an extra resonator. However, I am thinking of adding a 1/4 wave resonator pipe behind the 24" Magnaflow I currently have.
Are those dB levels in the cab or outside by the exhaust exit?

Looks similar to spiral flow..?

That has to effect airflow in a pretty meaningful way... no?

I didnt notice and change in boost or power levels. The diesel guys say it does not change EGT or back pressures....

The resonator dropped the tailpipe db by 11 and the in cab db by 9...
