I constantly hit the ground with the left muffler when driving off-road. Therefore, I myself will make an exhaust system with a 2-in-1 manifold. I have tig welding. I'll buy stainless pipes and make the muffler myself. And I'll make a different air filter. Now I have a homemade fiberglass air filter with a volume of 3.2 liters with 2 bells (bells) inside. I calculated the filter using Gordon Blair's book(Design and simulation of four-stroke engines. Gasoline consumption has decreased, 5 liters per 100 km. Carburetor engine 666cc (bore 79.00mm, stroke 68mm)
What is the tail pipe diameter of a standard 2-into-1 exhaust system? According to Gordon Blair's book, the optimal diameter is approximately 71mm. The exact diameter value will be shown by engine simulation in the program. I did a simulation of the Ural engine in the Lotus engine simulator program. With a tail pipe of 48mm (inner diameter) the results are poor. I will make a tail pipe of 60.3 mm (inner diameter). The simulation must be done in conjunction with a configured intake system and exhaust system. Therefore, I will make a different, resonant air filter.
Ya cause..... man can these things corner like they're on rails! 😁

I drug the muffler off doing that and had to stop and do a field expedient repair.
Sure, anyone drag the shifter side pipe. Let’s see you drag the other one! 😂

A way to literally shave a few pounds off of your Ural 🥴
😂, yeah, but why riding on 2 wheels if you have 3.
To practice skills to be able to stay alive in an evasive maneuver on the road when the car flies.....we highly recommend staying proficient! ;)
Ok, I can live with that.😎👍
