Here are some more information for High Flow Catalytic:
Just like it is important for a car to breathe in properly, it's just as important for a car to get rid of it's excess/waste gases. Restrictions will result in back pressure. Most cars straight out the factory do not come will free flow exhaust systems and use smaller diameter piping than the car actually needs adding a restriction. The materials are also not the best. If you look at the branches/exhaust manifold... you see that the bends are not bent in a mandrel manner allowing air to flow better. In addition the car has to pass emissions testing and has to be environmental friendly (Tree huggers!). Therefore a catalytic converter has to be fitted into the factory as well as silencers. Having a decent exhaust system put in can yield anything from 3KW to 11KW in most cars. That is alot more KW from such a small change to your system! Along with a cold induction system, you get more power for your rand than many other mods!
On a golf 1 and 2, we managed 5KW by changing branches and the rest of the exhaust system. The entire system cost us R2150 or just R430 per KW! Not bad hey! Some older cars we tested even go up to 11KW difference!
In a naturally aspirated car, we recommend doing your exhaust and induction first before you do anything else! Especially if you are going to put in higher duration cams in your car. The difference is amazing.
Let's look at the different parts of the exhaust system...
Branches / Exhaust Headers / Manifold
These take the gases (resulting from combustion) from the different cylinders and combine them usually into 1 pipe that will interconnect with another one (The head pipe) underneath the car. The best branches out there make use of mandrel bends and some are even ceramic coated for heat reduction. They are in addition flow-tested to make sure they will flow the air out in the best possible way.
Head Pipe
The job of this pipe is to connect the branches to the Catalyctic Converter and to the mufflers. Usually has a straight path without many bends. The less bends the better.
Catalyctic Converter
Converts dangerous chemicals such as hydrocarbons, carbon monoxide, and Nitrogen oxides into CO2 (Carbon dioxide), nitrogen, water vapor and oxygen. If you study a catalyctic converter in more detail, you will see it consists of honeycomb / beads coated in platinum and palladium. This inturn causes a chemical reaction which converts the bad gases to the good ones. Many people take these out for less restriction. The just don't care about our environment.... whateva!
Muffler
When somebody talks about a muffler, sometimes many people can't help but laughing at this English word. If you can't see why, then its better this way! The job of a muffler is to deaden the loud sound. It does this by getting the sound waves to bounce against each other thus canceling them. Many cars have a second muffler or even 2 parallel mufflers. The final muffler in many cases has 2 exhaust tailpipes already connected to it. This is usually done for looks especially when the tips are chromed. Another thing is that some mufflers are designed for a more aggressive/less aggressive exhaust tones.
Tailpipe
The last part of the exhaust system. This consists of the piping from the muffler all the way to the end. Many after market tailpipes include beautifully chromed tips either a single or a double tip. Many bends exist here since the piping has to curve up and over the rear axle. Some suppliers even have lights on their exhaust tips.
We hope you now better understand the workings of an exhaust system.

Acura Catalytic Converters Make the Car More Environment-friendly
Vehicles today are fast becoming a necessity rather than a luxury. The increasing demand for automotive vehicles has greatly affected the environment and the amount of air pollution is steadily growing. To help solve this problem, car companies, like Acura, are tapping into their resources to produce environment-friendly cars. One of the earliest solutions that worked was the installation of catalytic converters into the vehicles.
The Acura catalytic converter has contributed a great deal in reducing toxic emissions in the atmosphere. It is the stainless steel box mounted in the exhaust system. A catalytic converter contains a catalyst made from a metal such as platinum, palladium or rhodium. A catalyst is defined as anything that induces or accelerates a change. The base of the Acura catalytic converter is protected from vibration and shock by a resilient ceramic or metallic mat. Catalytic converters have been used on cars since 1975. Back then only one catalytic converter was installed; today, cars may have two or more depending on the engine configuration and manufacturer. The Acura catalytic converter changes poisonous gases to harmless carbon dioxide, nitrogen, oxygen, and water. Most cars today are equipped with a three-way catalytic converter. This refers to the three emissions it helps to reduce, carbon monoxide, hydrocarbons or volatile organic compounds (VOCs) and oxides of Nitrogen or NOx molecules. This type of catalytic converter uses two different types of catalysts, a reduction catalyst and an oxidization catalyst. Both consist of a base structure coated with a catalyst such as platinum, rhodium or palladium. The purpose is to create a structure that exposes the maximum surface area of the catalyst to the exhaust flow, while also minimizing the amount of catalyst required. Inside the catalytic converter is a honeycomb set of passageways or small ceramic beads coated with catalysts. A chemical reaction takes place within to make the pollutants less harmful.
An Acura catalytic converter operates in three stages. The first stage is the reduction catalyst. It uses platinum and rhodium to help reduce the nitrogen oxides emissions. Next, it reduces the unburned hydrocarbons and carbon monoxide by burning them over a platinum and palladium catalyst. This catalyst aids the reaction of the carbon oxides and hydrocarbons with the remaining oxygen in the exhaust gas. The final stage is a control system that monitors the exhaust stream. Produced results of this activity influences the way the fuel injection system is controlled. Still, unlike other cat-cons, high maintenance is not needed for an Acura catalytic converter. It just needs to be checked once in a while to ensure its efficiency. If vehicle performance begins to turn rough or if the car produces smoke from the tailpipe, it is recommended to have the vehicle check by a mechanic. Symptoms of a faulty or failing converter may include failing an emissions test, poor performance, increased engine temperature along with bucking of the car or hesitation. Neglecting these warning signs can cause expensive damage to the converter and may require a replacement.

magnaflow high flow catalytic converter? tacoma 2.7?
Hi, i have a 97 tacoma 2.7 5spd with a thrush welded muffler in with stock piping and cat. I was thinking about getting a magnaflow high flow cat to make it louder because its not loud at all. Would this change the sound at all or should i just go with a louder muffler like a flow 40?
change the muffler
