Buddah and Sandog, I did not realize your altitude was 5,000 ft. I ride the dunes at Glamis but it is starting to get too hot (120 in the summer) so I will be doing local trail riding and a few trips to pismo beach. Be sure to post your findings on the Graydon vs. Alien pipes and post some photos!!!

 

Will do!!

 

Well I can say that the B.G. dominates down low and mid compared to the Graydon. The Graydon seems to rev higher, but at a compromise. It is quieter then the B.G. The B.G. is lighter, easier to put on, and doesn't hang out past the rear grab bar. My impression is still pending. Big Gun is the absolute choice if your gonna ride woods or mx or anything technical. More testing next week.

 

The DMC alien has almost the identical performance of the Graydon.The DMC seem's to rev just a bit higher though.The Big Gun will destroy either pipe from low to mid.If you're a dune rider i would go with the DMC or Graydon.The Big Gun would work better in the woods.The Big Gun seem's to be louder also.Just my opinion.
