Review on Enhance Performance with Vance & Hines Power Duals Exhaust Chrome 16871 by Marc Oner

V&H almost always gets 5 stars for fit and finish and this is no exception. Installing a new head tube was a routine job for a mechanic. Remove stick tube. not as much. I had a set of Two Brothers Racing mufflers and of course the correct one was glued on. 3 hours of shaking, hitting and they got WD-40. The instructions say to attach heat shields to the free and locked head tube. DO NOT DO THAT! They were very painful to work around and I just took them off and put them on last. Also, the instructions say the O2 sensors should be installed last, but there isn't enough room to install them with the pipe. I had to remove it, install and reinstall O2. In total, Stage 1 with Screaming Eagle Big Sucker, TBR mufflers, Mastertunes II tuner and V&H head made 17 hp. compared to stocks. Air cleaner and cat kill power. I will add some photos as soon as possible. Hope that helps.
