How big is the diameter of the modified carbon fiber automobile exhaust pipe?
Generally speaking, most of the modification of automobile exhaust pipe modification starts from the middle and tail sections. The common method is to increase the diameter of the pipe and reduce the muffler, etc., and the emphasis on competition will be more linear. Improve the characteristics of straight car exhaust pipe modification (due to chassis interference, it is difficult to achieve true straightness), the path is shortened and the corners are smooth to reduce obstacles, but everyone should know that the shorter car exhaust pipe modification is The pursuit of high-speed horsepower (low back pressure), the slender type is good at low-speed torque (high back pressure). Faced with the weakness of blockage, the former has the problem of slow flow at medium and low revs, but when it reaches high revs, the exhaust can be very smooth.
For the modification of automobile exhaust pipes based on the premise of road use, in fact, a style with a longer full length should be selected as the condition for gas storage and growth rate, and then the change in pipe diameter can take into account the performance in the full speed range. From the experience of most people, the increase of the pipe diameter in the middle section is almost 10-15% more than the original one (the engine is not modified), that is, the naturally aspirated engine is about 55-60, and the turbine engine is about 65-70. Up and down, of course, if your car has a large enough displacement, and after some heavy upgrades, it has the strength of 400hpover, then it is necessary to use a pipe diameter of more than 80.
Regarding the configuration of the pipe diameter, from thick to thin or the same diameter from the beginning to the end, it is more appropriate for those who value torque, but if you are a horsepower seeker, it is suitable for the form of gradual enlargement. This bell mouth type The design is to slowly expand the diameter of the pipe, so that it expands more rapidly toward the rear, forming an exhaust gas speed-increasing airflow, especially in the case of continuous high speed, the more powerful, this is also a part of the current modified car exhaust pipe modification. item trend.
