Whether you prefer an automatic transmission or a manual transmission car, the clutch is a vital component in your vehicle. The clutch ensures a smooth transition between the engine and the gears while accelerating and decelerating. The flywheel side of the clutch connects directly to the rotary motion of the car engine via a pinion and shaft. This toothed flywheel is then loosely sandwiched with a clutch disc that connects directly to the gearbox with a second shaft. The clutch disc is free to either be pressed or pushed away from the flywheel. When pressed, both are forced to rotate together by friction, thereby transferring the engine rotation through the flywheel and disc to the gearbox. When separated by a gap, the gearbox is no longer forced to rotate and disengages, allowing changing gears.
A typical exhaust system consists of an exhaust manifold, catalytic converter, resonator, muffler and tail pipe all connected serially to a combustion car engine to flush out exhaust gasses. The exhaust valve allows entry of the hot exhaust gasses into the manifold. The main function of the catalytic converter is to completely neutralize partially combusted gasses such as CO and nitrous oxides that are toxic and harmful to the environment. The cat converter consists of ceramic and platinum or palladium layers. The gasses then move into the hollow muffler chambers of various sizes to eliminate most of the noise they carry from the engine. Resonance and changing directions between the chambers cancels out most of the noise.
The contact between the rotating disc and flywheel is made more efficient by ensuring rough ceramic surfaces between them for better grip. The engaging and disengaging is further controlled by a hollow pressure plate, that is layered on top of the clutch disc. This is riveted to the flywheel and completely encloses and hides the disc within it. It can be mechanically trigged to depress or withdraw, resulting in contact or no contact between the clutch disc and the flywheel. In automatic transmission vehicles, a torque converter consisting of an impeller, stator and turbine serves the same function as a mechanical clutch.
Often, car enthusiasts prefer to have a special muffler resonator to intentionally allow or enhance certain deep notes that are characteristic of some performance sports car engines. They also prefer to enhance the tail pipe with special fittings to enhance the visual appearance
Larger and multiple parallel tail pipes are also often associated with performance cars. More air intake and exhaust allow for extra breathing and combustion of fuel within an engine, and such engines often require larger exhausts.
Some of the most well-known brands of aftermarket replacement clutches and related parts include Luk, Exedy, Dorman First Stop, Beck/Arnley, Wagner, ATP, SKF and Blue Streak. Luk, for example, makes complete Clutch Kits as well as individual parts such as Flywheel shim, master cylinder or clutch Fork.
Some well-known makers of quality exhaust components include Walker, Fel-Pro, Dorman, ATP, Beck/Arnley and Blue Streak. Brands such as Magnaflow and walker are well known for their Catalytic converters and Findanza is known for flywheels. Fel-Pro is known for its gasket sets. Typically, catalytic converters, mufflers and pipes require replacements more frequently due to damage or wear and tear with regular driving.
