Looked around and did lots of research for slip on exhaust system for my 13 Vstrom 650. I decided on the Akrapovic 3/4 slip on system and haven't been disappointed in the least!
Great ordering experience from motosport--got exactly what I ordered and it came in a few days. Pipe went on pretty much exactly as the directions said, and the sound is amazing! Also, I thought for sure the "extra horsepower" was just mostly marketing BS, but it's not! From the very first ride with the Akrapovic system I was blown away by how much more pep, especially off the line, my bike has.
I have the Suzuki hard cases, and this exhaust won't fit with them on "as is", but I got out the powersaw and chopped off part of the hard case rack, so no problem! Would definitely recommend this pipe to anybody!
