Hi guys! I’m looking for more power for my LC4 640 year 2006. Offner Lufi and other spraying is already on, now I ask myself a question. Which end pot is recommended from the price performance ratio? Of course the Akras are unbeatable in terms of performance and sound, yet the price of my double pipe machine is simply too high for me. There are also other vendors such as Leovinci has someone had good experience with it. If someone knows something from other manufacturers I’m not angry either. Conclusion: I just want more performance at a reasonable price. Mfg car&bike
