Lots of companies out there promising big gains with their pipes, and slip ons. Truthfully if you don't open the airbox to compensate for the extra airflow of the pipe, and rejet the carb, or in FI remap the system it will do little but make extra noise.
HMF seems to be a popular atv pipe, I use an FMF Q4 series on my bike, and it does as advertised, but at the expense of noise which doesn't bother me to much being on the street, (I like being heard, be it animals or drivers)but loud pipes can cause issues on some trail systems,and make sure it has a spark arrestor on whatever system you choose. They are usually good for losing some weight on your machine also, but most require service, such as repacking them on a regular basis.
