Since I brushed the ECU and changed the high-traffic style, I have always had the idea of changing the high-traffic head section. After being recommended by the riders in the forum, I also learned about some head-stage brands, such as KT, DT, Jushi, JBOM, etc., workmanship And the influence is still the best JBOM, but the price is also the most expensive JBOM, so it was recommended by a car friend, and I received a second-hand JBOM300 molybdenum in the 3 series forum. The price is very cost-effective. It took only two months to replace it. Very clean, I thought it didn't match the X1 at first, and later compared with the original factory, I found that the front and rear interfaces of the 13 models of the 3 series are the same as the X1, but the rear interface is a little shorter, it doesn't matter, when it is installed It is enough to connect a section, so today I have time to go to the modification shop to install it. The head section of X1 is really difficult to disassemble. It took two masters to disassemble it for a long time, and it was very hard. The master's craftsmanship is also very good. , There is no air leakage, the installation took two hours, and the test drive after the installation was very cool. After installing the floor oil a few times, and driving more than 100 kilometers, the most direct feeling is that the exhaust is very smooth, there is no feeling of holding back before, a little throttle, the speed is very fast, and the turbo lag is basically gone, maybe it is me The feeling is relatively sluggish. It turns out that the low-speed shifting has no stumbling, and the acceleration is very smooth, a bit like a self-priming car. Overall, I think it's worth changing this header. Special thanks to “Mars Humans” for helping to take a few pictures of the header and installation
