Well here it is, its almost 100% done. Just getting some tuning fixed this today and tomorrow.
Truck: 1998 RCSB Chevy Cheyenne
Mods: 6.0 LQ9, 14 bolt rear end with 4:10 gears, 4L80E tranny = slow take off, tune, shorty headers, flowmaster exhaust.
This was my latest run, 60-110mph. when i get the tune fixed i will do a 0-120mph+
note in this one the tach was messed up reading to fast, i was not going above 6K rpm
Here is a small sound clip of the exhaust.

Dynoed in a few weeks ago at 317 rwhp and 345 rwtq
