Has anyone done this or know someone who has? Will it make a noticeable difference, is it worth it? Who makes a good pipe for this quad?

 

Any good slipon muffler for a 98-up 500 Scrambler will work.you arent going to see a huge improvment with just a pipe.You will get more out of a clutch kit than the pipe.I personally like the WhiteBros muffler but Aaen makes a nice one too.

 

i've got the hpd pipe and muffler and the airbox/jetkit mod. i noticed a good gain in power. in my opinion you have to move more air so without the airbox mods you won't get as much as possible out of the pipe.hpd has even got a nicer looking end cap on the muffler now.call rick and he will set you up
