Good luck finding a cheaper version. Most P250 pipes run $350-$400 bucks. Then you have to mess with the main jets. MRP claims theirs bolts on with no modifications. I've also seen an Xciting 250 with a White Brothers exhaust. But the header had a pipe welded to it to upsize it to fit the exhaust opening. Another option is to use a universal Supertrapp exhaust. They make a wide range of pipes with different diameter openings. Then by adding or removing the diffuser disks you can control the sound and backpressure. Its a pretty neat system.
