hey guys this is my first post. I recently baught a laro v retro 250 and I wanted to change the exhaust to make it a bit louder and faster. Im a noob at knowing whats what so I need some advice from some more experienced riders. The engine is 223cc single cylinder and I want to know what the best possible exhaust would be. I dont want to spend to much money iv heard that buying from japan is the best option in terms of cost. So please if anyone could recommend something that would suit my bike I would greatlu appreciate it as i have little to nill knowledge with this kind of thing.
