has anyone actualy used the hpr end cap

 

I have one, and like it. If you jet your bike correctly, it really "wakes the bike up". It is loud, though, and leaves you with no spark arrestor. Depending on where you ride, those negatives may be deal breakers. For now, those things aren't enforced when riding in most California sand dunes, so it works well for me.

 

if u could would you go back and buy a full system of a slipon.

 

Got one on my 04X, and like it (with ported intake and HPR 46 Lectron). When I first got it I ran the end cap on an all stock bike, and it was a nice increase, mostly bottom/mid.

I originally wanted the HPR Top Gun slip-on, but they where out of stock and the end cap was available, so I went that route. Happy with the end cap overall, but I am still goning to get the Top Gun pipe here shortly.
