An upstream air injection point, ahead of the catalytic converter, is also sometimes present to provide additional oxygen only during the engine warm up period. This causes unburned fuel to ignite in the exhaust tract, thereby preventing it reaching the catalytic converter at all. This technique reduces the engine runtime needed for the catalytic converter to reach its "light-off" or operating temperature. Many vehicles have a close-coupled catalytic converter located near the engine's exhaust manifold. The converter heats up quickly, due to its exposure to the very hot exhaust gases, enabling it to reduce undesirable emissions during the engine warm-up period.
Most end up reducing performance and adding weight, or worse yet – adding cost and doing nothing at all.

When it comes to improving your vehicle’s performance, you have two options. However, stainless still can be very expensive, as opposed to aluminized steel which is very affordable. It is also resistant to corrosion, just not to the level of stainless steel. Since there is no back pressure and the diameter is large enough, the engine will not use a lot of energy to push the exhausts out. While getting a cat-back performance exhaust system can be pricier initially, it can save on a lot of costs in the future. These exhaust pipes are usually wrapped in sound-absorbing materials, mostly fiberglass packing.
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 (05 duramax egr delete kit).
This picture is looking at the manifold end has a 60mm inlet ID and a 3 bolt flange where the outlet end has a 2 bolt flange and a 50mm outlet ID. Increasing your engine’s torque output gives you the power you need to haul heavy payloads and tow trailers, boats, campers, and more.
