Hello, I`m looking for a pipe for the 400 xplorer but want to have good low and mid range power for mud holes and trail riding? any opinions on the hotseat pipe or any other?

 

I love my Aaen Torquer it did the trick for me.tons of lowend and mid range but lost alittle on the top but hey I dont need to go fast just pull like a freight train.But you do need to clutch to the pipe and rejet the carb.I went with a green polaris primary spring and a Blue Aaen secondary and jetted it up to a 260 main jet and lowered the needle one notch.
