2002 800 RMK piping question

[500efisks]

I am looking for feedback on installing a single SLP pipe on this sled and was wondering if anyone has installed this pipe on a 2002 to 2005 800 RMK. Slp claims 11 hp with stock silencer ( I will be using an MBRP race can). Will I notice the difference and be glad I spent the $480 plus clutching and intake work to go with the pipe. Does it make a noticable improvment at higher elevations like 8000 ft. I ride mostly at 1600 ft. If I will not feel the difference I do not want to waist my money on a pretty shiny pipe.
