68 GTS Big Block Exhaust Manifolds

There are basically 4 choices. TTI headers. Schumacher headers, AccurateLtd repro manifolds and the originals. They all flow better than the originals. If you want the car to be numbers correct than go with the original manifolds but the real deal is quite costly assuming they aren't broken or cracked. For the price you could buy a real nice set of headers and improve performance quite a bit. Keep in mind that if you have a BB 4 speed car you will have to make some slight mods for the TTI's to fit and may have to buy the modified z bar. Trust me I know.
