There are subtle changes on the outside to let onlookers know that this is no ordinary F-150, such as a custom dual-intake hood, a custom front fascia and grille combo, and Shelby badging. For the interior, Shelby adds carbon-fiber trim, billet racing pedals, custom floor mats, and a serialized plaque. For lean-burn spark-ignition engines, an oxidation catalyst is used in the same manner as in a diesel engine. Emissions from lean burn spark ignition engines are very similar to emissions from a diesel compression ignition engine. Upon failure, a catalytic converter can be recycled into scrap.

Since 2003, we have specialized in building BMW M-models (and Tesla) with a refined selection of industry-leading, high quality products. Our 8,000 sq/ft installation facility and shipping headquarters is located in Anaheim, California. IE's advanced DroneTrap technology captures the pulse waves responsible for your B9 3.0T engine's exhaust note and draws them into dual mathematically tuned resonators. The internal ports are engineered to resonate these waves against each other in a process that selectively cancels out those responsible for annoying drones.

Straight-through, or flow-through, mufflers have perforated baffles and packing material that provides a conservative level of sound absorption while still keeping sound output moderately loud. Glasspack mufflers perform similar to resonators due to their design and lack of sound-absorbing packing material, so they tend to be louder and higher pitched. For compression-ignition (i.e., diesel) engines, the most commonly used catalytic converter is the diesel oxidation catalyst (DOC). This catalyst converts particulate matter (PM), hydrocarbons, and carbon monoxide to carbon dioxide and water. These converters often operate at 90 percent efficiency, virtually eliminating diesel odor and helping reduce visible particulates. These catalysts are ineffective for NOx, so NOx emissions from diesel engines are controlled by exhaust gas recirculation (EGR).

The cat back system’s pipes have a larger diameter than a standard set. So, your vehicle will get to perform better at a fraction of the work it outputs. An&nbsp
