Hi there i am new but i have read allmost ever thread on here for months, and i have yet to find many or a good talk about FAST LSXrt intake manifolds. I have a 2000 silverado with a 5.3L. a nelson tune, long tubes into a off road y pipe, 1-2 servos and shift kit. All the good bolt ons you all say to do. thank you for that! but my real question is Is the FAST LSXrt intake manifold worth it or would you be better off doing a cam with a stall and keep the stock intake manifold?
