3 Types of Exhaust Modifications for Performance Cars

3 Types of Exhaust Modifications for Performance Cars

An exceptional exhaust system plays a vital roles for performance cars particularly either on low or high torque ranges. The correct modification selection will gives you an extensive power gain as far as 50HP. It may unleash your high performance engine to its utmost potential. This is a great horsepower improvement items indeed.

There are 3 Types of Exhaust Modifications for your considerations:

1. The Axle-Back- The exhaust components after the axle inclusive of piping, muffler and tip. This is a minimum modification but may improve your torque and HP. The muffler option is either “Straight Type” or “S Flow Type”. 

2. The Cat-Back-The exhaust components after the catalytic converter. Replacing this section may give higher impact than axle-back in term of increased torque and horsepower. It may give improve the sound as well. This is a popular exhaust modification among performance car enthusiasts.

3. The Header-Back- This is the maximum modification involving header up to the tip. All components will undergo changes. It will give maximum gain on torque and horsepower but will be more costly than the Axle-Back or Cat-Back type.

Owning a performance car will never be better than having an improved exhaust system. You may choose from this 3 Type Exhaust Modifications options. If you are the beginner, the axle-back is for you. It is straight forward and you may select on having the most appropriate muffler for you preferred mode of driving.

Striking a perfect balance in between city drive or daily drive versus sports drive sometimes can be tricky. Street drive needs a low torque range power to maintain the best steer. There are tendency to speed up, stop, move, speed again and stop again. The S-Flow is the better option for this.

The S-Flow muffler will retain adequate pressure to be pushed when moving from static. However, the S-Flow will become less effective on high speed due to the S-Flow restriction. The exhaust gas cannot flow freely due to the curve in S-Flow muffler.

On long haul distance, the straight flow is better. It will discharge the exhaust gas straight to the air. When this thing happen, more air will enter combustion chamber to replace the volume and pressure deficit in the system. 

More air will bring more oxygen thus will allow for more rapid combustion to happen. The air intake, combustion and exhaust gas discharge shall be in equilibrium for the best performance in quest for getting maximum horsepower imprisonment.

4. Material Selection. Exhaust systems are made from various type of material. There are few different material in the market place to choose at. The most common types of steel used in exhaust systems are ferritic and austenitic stainless steels. There are also various grades of aluminized steels.

4A. The mild carbon steel. Low carbon steel has 0.04–0.3% carbon content and is the most common grade of carbon steel. Mild steel is a low carbon steel as it is defined with low carbon content of 0.05–0.25%.

4B. The 409 stainless steel. The 409 stainless steel is a ferritic stainless steel with less chromium and very little nickel. It is less expensive than 304 SS and will provide minimum corrosion resistance. The 409 stainless steel can contain up to 90% iron, meaning a magnet will stick to it and is prone to rust.

4C. The 304 stainless steel. The 304 stainless steel is the highest quality stainless steel used in the automotive industries. Normally found in exhaust tips, clamps, bolts and other small exhaust components where strength is very important. 

Type 304 is the most versatile and widely used stainless steel. Sometimes it is referred to by its old name 18/8 which is derived from the nominal composition of type 304 being 18% chromium and 8% nickel. 

Type 304 stainless steel is an austenitic grade that can be severely deep drawn. The 304 grade stainless is tough and nearly impervious to rusting because it has around 20% chromium and 10% nickel content in the alloy. 

The high nickel content makes 304 an austenitic stainless steel. Because of its low ferrous content, 304 can develop a golden color when exposed to high heat over time. The ferrous metal content is so low that magnets won’t stick to it, not like T409.

4D. Titanium. Titanium has a chemical composition of 6% aluminum, 4% vanadium, 0.25% (maximum) iron, 0.2%(maximum) oxygen, and the remainder titanium. It is extremely lightweight and strong. The sound can be fully differentiate when compared to standard Stainless Steel exhaust system because Titanium is less dense than steel allowing it to produce a more exotic “Metallic” sound.

4E. Inconel. Inconel exhaust tubing is made from an alloy of nickel, chromium and iron to withstand extreme heat. Utilized in various applications such as automotive exhaust systems, aerospace components, and industrial equipment. 

Inconel 625 or alloy 625 has approximately 65% nickel, 22% chromium, 9% molybdenum, and 4% niobium. Inconel is an amazing material for high temperature exhaust work. It manages heat far better than stainless steel and can be used to create components even lighter than Titanium.

From the above information, different type of material for exhaust system will deliver different results. From the high end to the most economical cost offered. True applications, satisfaction and budget will become key decision factors for any horsepower improvement projects. 

It is is wise to obtain the most efficient, the highest performance exhaust system available. Anyway on top op that, it is wiser to define practicality and budget before you’re going for your next course of action. 

Apart from these 3 Types Exhaust Modifications for Performance Cars, there are other amazing items that worth considering for a significant horsepower improvement. The improvement that we seek to excite.
