My Vance&Hines ProPipe Chrome finally came in today so I had a chance to finally install it. I already installed the heavy breather and EFK Gen 3 from Dobreck several days ago. I cancelled my ThunderHeader slip-on order and went with the complete 2 into 1 V&H system instead. I'm happy and the bike runs so much better of course, well maybe it needs a cam now :s:s I did notice on my test ride after installation that I get a pop for example upshifting from 1st to 2nd but the bike runs very smoothly. I guess I'll call Dobreck tomorrow and ask them some questions but I like this stage 1 set up and it looks really really cool on my Scarlet Red 2010 Road Glide Custom, like a hot rod.
