Ok I had my first race this weekend that they made us be quite, Calamity Pass enduro in Colorado. So I used my VOR tip. It easily passed at a 94 and we were suppose to be at 99 for this race. But I was totally disappointed with the performance of the bike like this. A little more on bottom but the middle sucked and the top end was only slightly down. So the question is has anyone compared the VOR tip to other systems? Is this the type of performance to be expected from all of the quite exhust systems? Thanks guys.
