Today I had a new Jardine exhaust system installed on my 2011 R3T by a bike mechanic with 35 years of full-time experience. I used his services because of the many posts I've read criticizing the fit of this system. Well, I wasted my money. He said that "the fit and finish is excellent" and no bending or other corrections were necessary to install the system. He said "it went right on". The other mechanic exclaimed how well the headers were designed and finished. I still have the stock a/c and today I put a Jardine friendly map in it (thanks Power-Tripp) from tune ecu till my PC5 arrives. With this exhaust the bike runs like a bat out of hell, with surprisingly strong improvement in 1st, 2nd and 3rd.
