I just got my new Dr. D exhaust for a YZ426 and am pretty disappointed with it. The end can was dented, the slip fitting on the header side was crushed, and there are scoring marks all down the header from what I assume was debris in their tubing bender. There are some other little things that bother me so I'm considering a switch to brand F if this is what is the norm for Dr. D pipes. I've had a pretty crappy week already so maybe I'm being overly critical. How were your exhaust system when you got them? Thanks!
