How to replace the left side exhaust manifold (LS3) on Chevrolet Corvette?

The procedure for left side Exhaust Manifold (LS3) replacement requires the removal of the engine sight cover followed by removing the generator. Start by detaching the bank 1, sensor 1 Oxygen Sensor from the Exhaust Manifold along with removing spark plugs and Catalytic Converter installation. Caretakers must remove the Exhaust Manifold bolts before pulling out the manifold but should disconnect the heat assembly as clearance demands that. Start by cleaning threads of the bolt hole in the Cylinder Head Exhaust Manifold before proceeding with installation. Place the Catalytic Converter onto the intermediate pipe but do not tighten the clamp because proper alignment requires the Exhaust Manifold to position on the Cylinder Head. The first step is to install the Catalytic Converter before applying gm p/n 12345493 (Canadian P/N 10953489) threadlock gm p/n 12345493 to Exhaust Manifold bolts in a 5 mm (0.2 in) wide band along the threads. Cuq manual specifies to position the Exhaust Manifold with a new gasket and install the bolts according to a specific sequence starting with the center bolts then alternating between sides while torqueing to 15 nm (11 lb ft) first and finishing at 25 nm (18 lb ft). After putting the bank 1, sensor 1 Oxygen Sensor back in its position at the Exhaust Manifold you should replace the spark plugs before putting on the generator and finally mounting the engine sight cover. The final step should include installation of the Catalytic Converter.

Chevrolet Corvette vehicles' Exhaust Manifold helps in channeling hot exhaust gases from the engine to the exhaust system making it perform well. Located positionable in various locations on the engine block, the manifold is meant to minimize intake reversion and optimize the gases flow through end components such as the catalyst converter as well as the muffler. Through the years various Chevrolet Corvette car models have used varieties for styles of exhaust manifold like the cast iron, stainless steel besides headers that have a less restriction to flow and have higher gas velocity. Of these headers, the greatest benefit is derived from their efficiency in increasing engine efficiency through pressure variation in exhaust scavenging. Moreover, fresh evolution popularized by some Corvette models is Yamaha's EXUP system that enables variable control of back pressure to make new adjustment according to the speeds of engine.
