The tech commented on the high quality of the exhaust and how well it fit. With the deepest and winningest racing heritage in the business, we have credibility thatwas earned one quarter mile at a time. Our friendly staff is experienced through product testing, research and development,and track competition.
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).
#19680 includes all the hardware necessary for do-it-yourself installation. Extensive testing on our in-house dyno has been used to ensure this SPEQ Series truck exhaust system not only sounds impressive but also has the performance bite to match its newfound bark. Consent to receive text messages for these purposes is not a condition of any purchase, service, or sweepstakes entry. So, if you are okay with the sound and performance then you have no need to replace your original exhaust system. OEM exhaust systems on the other and have crush-bent tubing made of normal steel.
To make a very long story short so far so good I’m happy with the product. I had 1 dinged tip out of the 4 that prob happened during shipping n y’all already have a new replacement tip on the way so customer service is great as well. Only thing I would change as previously stated would be a little more noise but again that wasn’t my main goal to being with. Hats off to what y’all do and please make more B9 Audi S4 parts n I’ll happily buy them. I regret not buying the IE intake but hey sometimes we all make poor decisions lol. Every vehicle-specific CORSA product is engineered and designed to match the unique properties of the vehicle it is designed for to deliver perfect fitment and performance.
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.
A catback exhaust system works by replacing the muffler and tailpipe with a more free-flowing design. Take full advantage of everything we have to offer with an upgraded CORSA exhaust.
