About How much horsepower more would I get if I put some headers on a 2000 Trans Am?
On ebay it says this 
acesetter Long Tube Headers - 98-02 Camaro/Trans am
Starting with 3/8"-thick steel plate and 1-3/4"-diameter carbon steel alloy tubing, each header is precision-crafted to insure proper fit and seal. The mandrel-bent tubing insures maximum flow to the 3"-diameter collector and on into the mandrel-bent Y-pipe. These headers replace the stock cast iron exhaust manifolds and have provisions for all smog and engine management hook-ups.
Includes: Off-road Y-pipe, clamps, O2 extension kit, fasteners and gaskets. About how much more horsepower would i get from putting this on a Trans am?
Is it a 3.8 or a 5.0? If it is the v-8, is it an Ls1? Hard to say if I do not know the engine size!
