All this means punchier low and mid range performance, an area in which the bone stock R15 was always found wanting. The entry level muffler is priced at around INR19,990, which certainly makes it an expensive proposition given the modest performance gains. You even have more expensive versions built out of exotic materials like titanium and carbon fiber. That said, well heeled enthusiasts won’t bother much with the price tag as they get to the intoxicating exhaust every time they give the throttle a twist.
