Anyone have experience with them on their bike? I listened to countless youtube vid's and they by far sound the best on my VFR (in my opinion). I'm asking because I saw some reviews that bring their quality into question. They're $500+ and I'm going to be expecting quality. I don't want to fork out any more for Two Bro's or equivalent as I'm having a hard enough time talking myself into buying the Delkevics. Just thought I'd see if anyone had some street time with them. Also, they mention having your bike dyno'd after the install. Is that really necessary? I'm still running my O2 sensors so I'm not concerned with leaning out.
