Was looking for a non-cat replacement exhaust for my Makita 6421 and this guy's small header pipes are cheaper than the OEM non-cat exhaust. He's got 100 percent feedback which is encouraging, just wondered if anyone on here had bought from him or had any thoughts on his designs. Out of Indianapolis, goes by SX Performance Parts now was chainsawperformanceparts before I think. https://www.ebay.com/itm/176021230814
