When I bought my banshee, it had Graydon Proline exhaust...says so on the header pipes anyhow...rear mufflers don't say anything...just round cylinders basically......I hear they stopped making them a while back...?! That because they were sooo good which made them expensive? Ha jk....what kinda info can u guys tell me about this exhaust....should I just take them off n go with something else? Thanks!!
