Motorcycle Repair: Stock Exhaust, dyno jet kit, stock exhaust

Question
How can I have my stock 2001 FLHT mufflers sound louder.
If that is not possible , does anything need to be done to the jets if I buy slip ons ?

Answer
I am going to assumn you have a carberated bike. Adding different mufflers will make it run lean. I would suggest adding a Dyno-jet kit and that will bring it back to the rich side. You can install it yourself with out problems
Good luck and happy riding
