This may seem like a stupid question, but I need to ask. Recently I have been looking at different aftermarket exhaust systems. I have found that many of them use a straight through pipe instead of using baffles like the stock pipes. My question is this. If the aftermarket pipe is straight through, what is the difference if you were to just take the stock pipes off and add additional pipe to the mounting location of choice. (ie. underseat, shotgun style etc.) No can, just additional pipe. Is there something that the can is offering that I am not seeing? Like I say, I am no exhaust expert, so I am sure there is something that I am not seeing here. Just curious what it is.

Thanks in advance

 

a whole lot of noise suppression for one thing

 

I would assume so, however I have heard these bikes with no exhaust and then I have heard them with a few of these straight through systems as well. To be honest I did not think there was that much of a difference between no pipes and the straight through. I have never heard the scenarios side by side so maybe there is more of a difference then I could really tell. If so, I wonder if the sound is the only difference.

 

Even though you can see straight through the can it still has a baffle in it that makes it quieter and provides back pressure. If you didn't have the back pressure you could burn up your valves not to mention **** off a bunch of people including the ones who ride around in cars with lights on them.

 

Thank you, that makes since. I guess even though sometimes you can't see something it does not mean that it isn't there. In this case I guess the side walls must act as some sort of sound buffer and catch the sound and pressure before it exits.
