Darryl came to us wanting a little more power and the ability to hear that LS3 breath, so we installed the following:
- Stainless Works 3.00″ collector longtube headers with 2.50″ X-Pipe and High Flow Cats
- Cold Air Inductions Intake System
- NGK TR55 Spark Plugs
- MSD 8.5mm spark plug wires with DEI boots
- SLP Performance 160 degree thermostat
- Custom Dyno Tune
Intake only: The car made 382.38whp/372.50lbft
Longtubes/Tune: The car made a stout 416.56whp/403.06lbft.
That’s over 34whp peak whp and 40lbft of torque from Longtube headers and a tune alone, not to mention all of the gains in the mid-range.
