These look like standard mufflers with a VERY unusual side entry rear exit configuration. Notice the heat discoloration at the intersection where the split occurs.Heat discoloration shows up where there is a flow restriction. Notice also the heat discoloration just after the pipes enter the silencers. It is AMAZING the engine makes the power it does through this congestion. Features Only 10 lbs [catless and non resonated version] 304 stainless steel piping Smooth air flow for maximum horsepower Compatible with both manual and automatic transmissions TIG welded to perfection... The main functions of exhaust systems are increasing horsepower and improving your engine sound.
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 block off plate 6.7 powerstroke).
From cat-back exhaust systems, emissions compliant catalytic converters, performance mufflers to custom exhaust parts, buy the automotive part your vehicle needs. In addition to boosting your horsepower, cat-back exhausts can make a massive difference to the sound of your car, especially if you choose exhaust tips designed for acoustics. Basically, catback exhaust systems upgrade regular exhausts, improving the flow of exhaust gases and the performance of your engine with wider pipes and smoother bends.
Finished in Panther Black Metallic over Onyx and Red leather, the car is powered by a 6.2-liter V8 linked with a six-speed automatic transmission and a limited-slip differential. Purchased by its current owner in February 2022, this G8 GXP is now offered with a reproduction window sticker, service manuals, a car cover, the removed exhaust system, a spare set of wheels, and a Michigan title. A catalytic converter is an exhaust emission control device which converts toxic gases and pollutants in exhaust gas from an internal combustion engine into less-toxic pollutants by catalyzing a redox reaction. Catalytic converters are usually used with internal combustion engines fueled by gasoline or diesel, including lean-burn engines, and sometimes on kerosene heaters and stoves. Whether you’re accelerating up a highway on ramp or passing slower traffic, improved acceleration lets you get up to speed more quickly. Gain horsepower, increase torque, and give your truck a more aggressive exhaust note with a new exhaust system.
One main reason for choosing to remain with a stock system is because it comes already installed on your vehicle. You should know the difference between a dual exhaust and a dual exit exhaust system. But it is easy to mistake a dual exit exhaust for a dual exhaust system. The materials are often 304 stainless steel or aluminized steel. The stainless steel is usually coated in special metals that make it corrosion-resistant. This means there will be a reduction in the amount of load on the engine, leading to higher mpg and fuel efficiency.
The remaining waves produce the deepened and enriched exhaust acoustics you love. Stillen offers a variety of exhaust systems for many vehicles, both foreign and domestic. The muffler is a glass filled, large chamber design that provides the optimal amount of exhaust velocity for the engine while producing a great low rumble sound - without any annoying buzzing, "racer" sound. The high clearance fitment dramatically reduces the risk of getting hung-up on obstacles when off-roading. We’ve been helping customers with performance upgrades since 2006, and have a staff full of people who can help answer your questions. Our customer service — from our low prices to our fast shipping — has earned us a reputation with a legion of fans.
Next we have the option we refer to as the Cat-back system (sometimes also known as "with Front Pipe" exhaust). One of the most noticeable changes after installing a cat-back exhaust system is the sound. The exhaust note becomes deeper and more pronounced, giving your vehicle a more aggressive tone. The specific sound varies depending on the muffler and pipe design, allowing drivers to choose a system that matches their preference for loudness and pitch.
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 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.
Exhaust systems also play a role in reducing noise levels, improving engine performance and reducing fuel consumption. To get the power level up to 785 hp, Shelby installs a Ford Performance supercharger, as well as a new carbon-fiber air intake tube, high-performance fuel injectors, and an aluminum heat exchanger. A Borla (cat-back) exhaust system rounds out the list of powertrain modifications.
When used in the context of aftermarket parts or performance upgrades, "cat-back" is used to indicate which section of the exhaust system the parts replace. Cat-back systems are available as both single- and dual-exhaust. All Thermal R&
