I would rather put the 200-300 buck header money on something else as the stock exhaust manifold is a good as you can find on a Base engine, maybe better than the 4bbl Pontiac OHC. Unless you really dig the "split manifold" sound. I do -- that makes it a tough call! Is it my dialup or is there no rpm reference or torque numbers? Arn't there some trailblazer headers already out there, or is it just for the 5 cylinder pickups, seems like Jrs or something like that. Fives also have a nice stock manifold.
