Hi, y'all!
I just got my truck back from Gibson Performance Exhaust. They used my srt for r&d to develop their exhaust. Here are the numbers
before - completely stock
HP = 406.0
Torque = 417.8
After - prototype cat-back system
HP = 417.8
Torque = 456.7
The before run was done about ten degrees cooler than the after run, so all things being equal, the results should be a bit better. Sound is much better, too!
Here are the links to the charts:
