:read:with due respect sir, I lived in texas all my life and there has never been any laws passed on motorcycles requiring catalytic converters. this article reflects motor vehicles and does not state anything about motorcycles in particular.:cheers:
http://www.epa.gov/otaq/regs/roadbike/420f03045.pdf
In motor vehicles, the catalytic converter is an anti-pollution device that changes toxic byproducts of burning fuel into gases naturally. Some drivers hope that by eradicating the converter you can boost performance whilst others seek to replace converters with parts of normal exhaust pipes in effort of avoiding extra costs. Those actions are against the Texas state law and any violators are charged with up to $25,000 fine.

Notes:
General applicability: These standards apply to 1978 and later model year, new gasoline-fueled motorcycles built after December 31, 1977, and to 1990 and later model year, new, methanol-fueled motorcycles built after December 31, 1989, and to 1997 and later model year, new, natural gas-fueled and liquefied petroleum gas-fueled motorcycles built after December 31, 1996, and to 2006 and later model year new motorcycles regardless of fuel.
a Useful life and warranty period are expressed in years and kilometers, whichever comes first.
b Starting with the 2006 model year EPA re-defined Class I to include motorcycles with engines smaller than 50 cubic centimeters. These new previously unregulated vehicles are Class I-A, and the pre-existing Class I became Class I-B.
c This is an optional standard that allows manufacturers to average their emissions or transfer emission credits across classes.

In the long and dry read which is the EPA's Control of Emissions From Highway Motorcycles, the most misunderstood and eyebrow-raising passages regard special exceptions for "Custom Motorcycles" and "Motorcycle Kits." The latter of these aroused the most confusion and ire because bike owners would be limited to only one Kit Bike in their lifetime. This provision led to much speculation and rumor that riders could only own one custom bike in their lifetime.
The 2004 EPA rules specify that riders can own a bike, built from parts by themselves or others, which is exempt from EPA emissions requirements. What defines the machine a Kit Bike, is that the owner can legally ride the non-emissions-compliant machine as much as they want. The catch, of course, being every rider is entitled to just the one Kit Bike in their lifetime.
