By just modifying the exhaust tail section of the car, you will not be able to increase the horsepower and even if you did, the improvement would be small to negligible. If you happen to replace the entire exhaust pipe system with high-output models then you will get results. The high performance exhaust pipe is much better than the original one. The ultimate guide to performance exhausts, alloy wheels and tyres will reveal more on that
The sport exhausts are thick with smooth inner walls and small curvatures. This design helps for the high rpm of an engine and the actual gas can smoothly speed through the pipes, so you will get better horsepower. Do not trust the unknown small workshop productions that claim to increase power without losing low rev torque.[I:http://autorepairarticles.com/autorepairarticles/wp-content/uploads/2012/04/DawnChapman6.jpg]
Talking of the universality of a modified exhaust system in car modification, this time – the discussion falls upon common errors on the modified exhaust system. The original exhaust system is from the manufacturer which is built with repeated tests for the vehicle’s dynamic performing. Also – the manufacturer is trying to build the vehicles to be environmentally friendly and with good fuel economy, also adding cost of production and other aspects to the design of products.
Is it true that when the back pressure is lower the dynamic performance is better? Of course not, the first thing you do is measure the dynamic performing of said car. Many companies, specialized in high output models understand what the drivers want.
Cars’ power output characteristics are very important but to make your car powerful with a loud exhaust system is not a very good idea. That will be too much noise for the city environment and you may have troubles very often with the police officers. The loud exhaust systems are better suited to racing cars, which are driven outside the city.
The original exhaust manifold is usually a large number of mold cast iron products. Factory exhaust manifolds will not consider each cylinder the length of the actual pipe. The length of lead to each cylinder exhaust manifold distance run, brings conflict with each other, to form a block.[I:http://autorepairarticles.com/autorepairarticles/wp-content/uploads/2012/04/DawnChapman28.jpg]
Modified equal length exhaust manifolds, will use the smooth inner walls of stainless steel. Pay attention to the still manifold stand and then the angle of the site, special treatment of the welding process and try to ease the corners, to reduce the resistance, to accelerate the effect of airflow. Each cylinder exhaust coming together in the structure of the exhaust manifold will increase of a set of pipeline, such as four-cylinder car frequently used.
Known as the “space metal”, titanium alloy has high strength, corrosion resistance, and excellent heat resistance. The density of titanium is only 60% of steel, but its intensity is even better and the more lightweight titanium alloy material offers the same intensity exhaust pipe as a stainless steel model. This is in order to reduce weight and has made a great contribution to the ultimate guide to performance exhausts, alloy wheels and tyres and lightweight modified cars.
