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&nbsp
