Only thing I don't like about my bike is the wimpy sound the stock pipes make. Any and all advice on stock mods or aftermarket full-systems and slip-ons is appreciated. What have you all done to get your bike sounding good? Has anyone tried Highway Hawk slip-ons?
How long have you had your bike? I found that the sound got a little louder and deeper with time.
Playing with the exhaust on the Classic can open you up to a whole lot of issues such as decel popping and the potential for a whistling exhaust.
If you are willing to risk modifying your mufflers and reducing their value (note that fully stock mufflers go for quite a bit on this model) you might consider the 1.25" diameter hole saw mod. There are two plates in the centre of the baffle tube that you can drill out from the back of each muffler.
Try just the first plate on each muffler first and see how you like it. This will not likely cause any added decel popping and it may just be loud enough for you...and remember, it will get louder with time.
If you want a little louder and deeper sound, you will need to drill out the next baffle plate in each muffler, but be careful, the Catalytic material is right behind the second plates. This is the riskiest plate to drill out as it has a tendency to fall into the muffler. The plate can be retrieved with a magnet and a lot of patience, but this necessitates removing and shaking the mufflers. There is also the risk of getting a whistling sound on decel by removing this second baffle plate. I got the whistling and so did at least one other forum member who did this mod. Most others who did this mod got no whistling, but then most of them owned Nomads, Voyagers or Vaqueros.
After drilling out the second baffle plate in each muffler you are likely going to notice more decel popping. A good adjustable
fuel manager will help with this as you will need to add more fuel just off idle.
I didn't try aftermarket slip-ons or full exhaust, but those who did definitely had decel popping issues until they got a good fuel manager. Note that the "automatic" Cobra fuel manager is the least
likely to help with the decel popping.
Hope this helps!
