Installed the full system today. Followed the instructions to the letter. Had a slight exhaust leak initially, worked the headers in alittle better & problem gone. 2nd problem. The collector the leads into the muffler is rubbing on the center pivot bolt on the linkage arm for the rear shock. I have tried to work it away from this w/ no luck. Has anyone ran into this problem? If so, any advice would be appeciated!
