Alberta Canada here...signing in for the first time
#1
So I just bought my first brand new vehicle.
2013 GMC Sierra RCSB 4x4 5.3 6spd SLE Onyx black.
I figured it was about time to step up to fullsize platform after spending 2 years modifying a 2004 RCSB Colorado ZQ8.
Bought the truck yesterday and today I bought a K&N air intake system.
Next mods...
Corsa sport catback dual side exit.
Long tube headers and ORY. Opinions on brand to go with are welcomed
4.10 gears.
3000 stall converter.
tune.
and probably a 2-3 drop/level.
