I have no idea what "another route" might mean.
But anyone considering modifying their emissions systems should take into account the possible repercussions. For example, here is Texas take on it. I woiuld guess other states have something similar.
Texas law prohibits any person from selling, offering for sale, leasing, or offering to lease any vehicle not equipped with all emission control systems or devices in good operable condition. Violators are subject to penalties under the Texas Clean Air Act of up to $25,000 per violation. Buyers are advised to have the vehicle checked for all required emission control devices prior to purchasing a new or used vehicle.
Dealers likely will not take them on a trade in.
