The dasa seems a little loud form an earlier video when it was racing that Race Rzr. I ha dther eexhaust on my teryx and it performed awesoem but was too loud.
I love the sound of the weller exhaust with those DMC cans. sweet sound and not as high pitched!!!!
I like the beauty plate on the Gibson, The Dasa header looks the best and that collector sure is pretty. I like the dual mufflers on the WR one, i am sure their header will look nicer on the production kit.
