Arrow designed and developed a range of high-performance exhausts fitting 2-strokes street bikes. Muffler is made with low-thickness metal sheets, oxy-acetilenic welding with hand-made re-working to ensure the smoothest flow of gases possible for the maximum performance and it is treated with a transparent finish (heat-proof paint), underlining the details of the welds and structure of the muffler. The silencer is available in the Round Sil version (in titanium, kevlar or 100% carbon fiber) and in the Mini Thunder version, a diamond-shaped section, in titanium. Street 2T exhausts give a very good power gain at mid- and high-range, without compromising the functioning at lower rpm levels. These exhausts are the top-level choice for street 2-strokes bikes, are easy to fit and, depending on the application are available in a street legal version.
