Free Flow Exhaust System
as made by AUTOMECH ENGINEERS, Mumbai...
What is a Free Flow Exhaust System
A standard exhaust system of any cart consists of a cast iron manifold, fitted on to the engine cylinder head to route exhaust gases out of the engine’s cylinder. This provides an exit for the exhaust gases. A Free Flow Exhaust System consists of pipes with a calculated length that allows a free passage to the exhaust gases. These pipes help in clearing the exhaust gases more efficiently with lesser restriction than in a (standard) stock exhaust system and translates into improved power delivery. An increase in power by around 8-12% and torque by about 6-10% is achieved. This results in enhanced performance (driving pleasure).
A free flow system consists of:
=> Header
=> Auxiliary Muffler
=> Expansion Chamber
=> Intermediate Pipes
=> Muffler (Stainless Steel)
=> Tail Ends
HEADER
The header is the main component of the free flow system. It is made up of pipes of a calculated length so that the exhaust gases are evacuated from the engine cylinder quickly and efficiently. This increase in exhaust efficiency results in better engine response and performance. All the pipes in the header are mandrel bent for dimensional consistency.
AUXILIARY MUFFLER
Most cars come with auxiliary mufflers from the factory. In a free flow system, the auxiliary muffler can be retained or an expansion chamber fitted in its place. The fitment of this muffler reduces the sound at the rear muffler. This muffler is of a straight-through design filled with a combination of glass wool and steel wool.
EXPANSION CHAMBER
This piece of equipment fits in the system after the header. Its main function is to boost torque in the engine’s power band. It can be fitted in place of the auxiliary muffler.
INTERMEDIATE PIPES
These pipes join the header to the expansion chamber to the rear muffler. The dimensions of these pipes determine the sound of the exhaust system.
MUFFLER (STAINLESS STEEL)
As in a stock car’s exhaust system, the sport exhaust also consists of a muffler to reduce the sound of the exhaust gases exiting the cylinder. This muffler features a perforated straight-through pipe with the surrounding area filled with a combination of steel wool and glass wool to tone down the sound of exiting exhaust gases as well as allowing minimum obstruction to the gases on the way out. The muffler also emits a sporty sound, a benefit of the straight-though design. These mufflers are available in mild steel or stainless steel. The stainless steel mufflers, in addition to enhancing the looks of the car, also last longer than ordinary mild steel ones. The muffler design can be tailored to get the sound to suit individual choices.
TAIL ENDS
Tail ends, which go on the mufflers, add to the cars appearance and are available in a variety of shapes and sizes.
