Although phosphorus is no longer used in gasoline, it (and zinc, another low-level catalyst contaminant) was widely used in engine oil antiwear additives such as zinc dithiophosphate (ZDDP). Beginning in 2004, a limit of phosphorus concentration in engine oils was adopted in the API SM and ILSAC GF-4 specifications. Although catalytic converters are most commonly applied to exhaust systems in automobiles, they are also used on electrical generators, forklifts, mining equipment, trucks, buses, locomotives, motorcycles, and on ships. They are even used on some wood stoves to control emissions.[5] This is usually in response to government regulation, either through environmental regulation or through health and safety regulations. Custom setups, especially for vehicles that do a lot of off-roading are also available.
Installation was super easy, and did it myself with only ramps. When IE claims 'no-drone' they really mean it - the sound is perfect! The youtube videos do not do a good job capturing the sound quality, but trust me, it's the best overall setup for your car at a reasonable price point. Enjoy a tuned and enjoyable exhaust note without any raspy leaks ruining the show. Our exhaust system assembles with our wide-width stretch clamps designed to seal and pull your exhaust connections together.
Your engine’s performance and acceleration are then increased. The mandrel-bent tubing reduces the level of back pressure in the exhaust manifold as the larger diameter reduces restriction to the flow of exhausts. REMARK is an exhaust system manufacturer specializing in producing high quality, hand crafted exhaust components and systems for a range of vehicles. All products are made from 304L "Aircraft" Grade stainless steel. Milltek's 3.15" (80.00mm) Sport Catback Exhaust System has multiple tip options in Polished, Cerakoke Black, Brushed Titanium, Burnt Titanium and Carbon fiber. You get the only the best with SPD's 3" resonator delete pipes. These 304 stainless steel pipes are ..
This is achieved by burning off the excess hydrocarbons which result from the extra-rich mixture required for a cold start. Slightly lean of stoichiometric, the porsche 986 exhaust gases from the engine contain excess oxygen, the production of NOx by the engine increases, and the efficiency of the catalyst at reducing NOx falls off rapidly. However, the conversion of HC and CO is very efficient due to the available oxygen, oxidizing to H2O and CO2. However, the efficiency of the catalyst at reducing NOx is good, and the production of NOx by the engine decreases.
There are several factors to consider when selecting an exhaust system for your vehicle, including noise level, finish, price, style, and installation difficulty. As you move through the versions here, you’ll notice that the more complete the system, the more expensive it becomes. In exchange, you'll get more performance and sound benefit out of the system. To sweeten the pot, our exhausts come with significant savings once you start bundling multiple pieces together.
There are loads of options, all offering different benefits, and the amount of research you do can quickly turn to frustration when you realise the minuscule differences between the many options. OE-quality exhaust products engineered for today's medium-duty and heavy-duty vehicles. The single 60mm is split into twin 50mm pipes to the twin silencers.
Engines fitted with regulated 3-way catalytic converters are equipped with a computerized closed-loop feedback fuel injection system using one or more oxygen sensors (also known as Lambda Sonds or sensors). Other variants combined three-way converters with carburetors equipped with feedback mixture control were used. An unregulated three-way converter features the same chemical processes but without the oxygen sensor, which meant higher NOx emissions, particularly under partial loads. These were low-cost solutions, typically used for retrofitting to older cars or for smaller, cheaper cars. Axle-back exhaust systems replace only your vehicle’s rear exhaust section, usually consisting of items behind the rear axles, like rear exhaust pipes, muffler, and exhaust tips. A
