Stock Manifolds
On an LS1 thats partially true but shorties compared to the Lt1 stock manifolds are way better. Anything is better that the Lt1 stock manifolds. The LS1 stock manifolds are much better designed. Guys usually dont get shorties on an Ls1 because the gains arent worth the $$. THey go straight to longtubes.
