00:03 The exhaust is good
00:05 So, where are we now?
00:07 We are at Enanthapillai's garage
00:09 We are going to talk about exhaust
00:11 You might be thinking, why do I have an aftermarket exhaust?
00:15 So, today we are going to talk about a small difference
00:17 between stock exhaust and racing performance exhaust
00:22 So, this is your Paul Win
00:24 and welcome to VICE Park
00:26 Today, we are going to talk about exhaust
00:28 Exhaust comes in 4 components
00:30 in a car
00:32 In a bike, you will see 3 parts
00:34 In a car, you will see 4 parts
00:36 Header, Cat, Muffler and End Can
00:42 These 4 components are in a car
00:44 But in a bike, I have seen a header, cat and end can
00:50 That is, slip on exhaust
00:52 If you ask, where is the muffler?
00:54 We are going to talk about that
00:56 Watch the full video
00:58 Now, we are going to draw a diagram
01:02 [Music]
01:07 In this diagram, you have header, cat, muffler and end can
01:14 So, this is a car
01:15 So, what is a header?
01:16 It is the gas that is burnt from the manifold
01:20 So, how does this gas produce sound?
01:24 In a 4 stroke engine, the gas is produced in the 3rd stroke
01:32 So, when the 2 valves are closed, the sound is produced
01:36 The air compressor produces sound
01:41 When the valves are closed, the sound is produced
01:46 In a car, the sound is produced in 800 degree
01:52 It goes to the cat
01:54 In this, the sound is produced by the waves
01:58 I will tell you what are those waves
02:00 It is called amplifying
02:03 When the sound is amplified, the waves are produced
02:05 The waves create back pressure to the car
02:09 What is back pressure?
02:10 If the exhaust is not produced, the car will have a power drop
02:15 When the back pressure is produced, the waves are produced
02:19 The extra oxygen is released into the header
02:23 When the air mixture is produced, the performance is better
02:33 The back pressure is produced
02:37 This is the back pressure
02:39 There are many harmful gases in this
02:42 Nitrogen oxide, hydrocarbon and hydrogen monoxide
02:50 It goes to the cat
02:52 The chain reacts with the metals in the cat
02:56 It produces carbon dioxide, water and hydrogen
03:01 You might have seen in the car
03:03 When the AC is switched on, the exhaust water comes out
03:08 The exhaust water comes out in the fuel time
03:12 This chemical reaction produces the carbon dioxide and water
03:19 This is the cat
03:21 The cat has an oxygen sensor
03:23 This oxygen sensor produces the oxygen and fuel
03:26 This is the carbon dioxide
03:27 The cat has another sensor
03:29 This is the proper sensor
03:33 These two sensors go to the AC
03:36 This is how much oxygen is released
03:38 This is how much oxygen is released
03:40 This is how much oxygen is released
03:42 When the oxygen is released, the ECU reduces the oxygen level
03:50 When it is reduced, the performance is not good
03:55 This is because the cat does not work properly
04:02 This is the reason why many people use the power drop
04:06 You can change the cat and clean it
04:09 After the cat, we have the muffler
04:13 I will show you the picture of the muffler
04:16 This is a 3-chamber muffler
04:18 The exhaust comes in and there is a braffle
04:22 The force reduces
04:26 The second chamber comes in and there is a braffle
04:30 The back pressure is created
04:33 The rest of the waves go to the third chamber
04:43 The cat comes from the header to the muffler at 800 degrees
04:52 The muffler comes to the end chamber at 400 degrees
04:58 The muffler comes to the end chamber at 100 degrees
05:05 This is how the heating and cooling process is done
05:08 The chemical and poisonous gases are reduced
05:13 This is how the process is done
05:16 The stock exhaust is very well done
05:31 The stock exhaust has a lot of restrictions
05:37 For example, the exhaust should be at 80 decibels
05:47 The engineers have invested a lot of time and knowledge
05:58 To bring a proper product
06:01 That is why it is heavy
06:09 The muffler and the end chamber are the same
06:15 This is the picture of the muffler
06:19 The muffler is here and the end chamber is attached
06:23 This is how the exhaust of a bike is
06:28 The muffler and the end chamber are the same
06:35 This is the stock exhaust
06:38 Now let's look at the aftermarket exhaust
06:41 This is the aftermarket exhaust
06:44 The aftermarket exhaust is direct free flow
06:49 The exhaust is not dripped from the header
06:53 The muffler is open free flow
06:57 The muffler is here and the end chamber is attached
07:04 The exhaust is direct free flow
07:13 Many people say that direct exhaust will increase the performance
07:19 But there is a catch
07:23 There is an oxygen sensor in all the bikes
07:28 There is no catch here
07:33 The gases will be released from the ECU
07:37 The power will be dropped
07:39 The power will not be produced properly
07:41 Many super bikes require a power commander
07:46 And a fuel management system
07:50 The exhaust is used to bypass the fuel system
07:55 You can utilize the power of the free flow
07:59 Coming back to the free flow
08:01 The exhaust sound will be heard here
08:04 The muffler is here
08:07 There is no block here
08:09 Some people use gas or silicon wool
08:15 The exhaust air will be transferred here
08:24 The exhaust air will be transferred here
08:33 The sound will be light but the back compression will be heavy
08:39 So the exhaust sound will be loud
08:42 This is the difference between the stock exhaust and the free flow exhaust
08:47 The stock exhaust has a lot of technology and it is heavy
08:54 But the free flow exhaust is made of stainless steel, light weight metal and titanium
09:03 The stock exhaust does not have a full bend pipe
09:08 Only in India, they use titanium
09:13 That is why the stock exhaust is heavier
09:16 The free flow exhaust is light
09:20 This is the difference between the stock exhaust and the free flow exhaust
