I installed this exhaust system on a new CRF250L Rally with only 50 miles on it and have since ridden the bike for another 40 miles. Together with a EJK controller the bike feels like a different machine altogether. It has come alive response wise. Super easy install and system looks great. Love the looks and performance!Read All Reviews
