I`m sorry if this has already been published, but I can never get a direct answer. I hear: „No, it`s illegal“, „Yes, none of the cats are okay.“ Anybody? Will I fail controls and emissions? Thank you! Your muffler should be in good condition and look as new as possible. Your muffler should also look and function similar to your vehicle`s original. You may need to repair your exhaust system if another component, such as Your catalyst or resonator has holes or leaks. The exhaust system includes manifolds, seals, exhaust pipes, silencers, resonators, exhaust pipes and support equipment. For vehicles manufactured before 1984, catalytic converters are considered only as part of the exhaust system and not as part of the exhaust system. State laws and inspection criteria differ between what only counts as an exhaust system and what counts as an emissions system. In short, for vehicles manufactured before 1984, the catalytic converter (if the vehicle was originally manufactured with a catalytic converter, it must have one) is visually inspected only for cracks or leaks as part of the exhaust system (1984 was the year catalytic converters were standard equipment. Prior to 1984, some manufacturers supplied vehicles equipped with catalytic converters, others did not). If you make any changes, you must comply with Texas emissions laws. Any changes you make must not result in your vehicle being emitted from what the law requires. In addition to your muffler, your exhaust system must have a catalytic converter. If your exhaust system has additional components such as resonators, do not remove them either.
You also can`t add additional components that directly increase your emissions. Unlike other states that enforce a decibel limit for exhaust system noise, Texas does not have a decibel law. However, the Texas Corporation Code states: „A motor vehicle shall be equipped with a muffler in good condition that operates constantly to avoid excessive or unusual noise.“ Ultimately, your exhaust system should retain most of the same emissions and performance parameters as your car or truck`s original exhaust system. Pressure, noise and design should closely match your vehicle manufacturer`s recommendations. If an inspector thinks your vehicle deviates too far from the original specifications, you may need to remove all your modifications. Texas law states that no part of an exhaust system can pass through the passenger compartment. The exhaust can also only be emitted from the rear, side or top. A silencer must be mounted on the vehicle with special exhaust brackets. These requirements are strict enough to ensure that the muffler runs continuously.
Just get „Pass Thru“ silencers and you`re good to go. (b) No person shall use a silencing (cut-off, bypass or similar device on a motor vehicle). A muffler is a series of chambers that absorb exhaust gases from an internal combustion chamber engine and emit them through a pipe to the rear of the vehicle. This process effectively reduces the noise of a running engine. Properly functioning silencers also reduce the amount of harmful emissions released into the environment. The Texas Transportation Code requires that all registered vehicles be equipped with a muffler and meet the standards set by law. If you want to make changes to your exhaust system, or if you need to repair your existing exhaust system to pass inspection, Midland Muffler and Brake can help. We are experts in silencers and exhaust systems and will inform you of any authorized changes or repairs necessary. We repair all types of vehicles, including vintage cars.

Texas State law states that the owner or operator of a new motor vehicle or engine equipped with an exhaust emission system from model year 1968 or thereafter may maintain the exhaust emission system in good working order and may NOT intentionally remove or render the exhaust emission system or any portion thereof inoperable in the State of Texas. except in the case of the installation of another exhaust emission system or part thereof. 2. For vehicles manufactured before 1996, the vehicle must travel at least 50000 miles and have a legitimate reason to remove the catalytic converter or it cannot be legally removed. For vehicles manufactured from 1996 onwards, the vehicle must be at least 80,000 miles old and have a legitimate reason to remove the catalytic converter or it cannot be legally removed. 3. The Federal Vehicle Act of 1995 and more recent also requires automakers to guarantee the catalytic converter and other key emission control components for 8 years, or 80,000 miles. Smaller emission control components and emissions-related components must be warranted for 2 years or 24000 miles.
This warranty only applies if: Texas requires all vehicles to be equipped with a muffler. This means you can`t run your car or truck without one. Your muffler must be completely intact and must not contain any punctures. You also can`t fix a muffler with a hole; You will need to replace the muffler instead. If you try to get your vehicle inspected with a patched muffler, you will fail. Holes, leaks or patches on the silencer, resonators, exhaust pipe, exhaust pipe or catalytic converter. The vehicle is not equipped with a silencer. Each joint is loosened or leaking, including the manifolds. Does not contain minor leakage on the exhaust gas control valve (manifold damper or heat riser valve).
The dispenser is cracked or broken, causing a leak. The exhaust system is not attached to the vehicle by mounting brackets for exhaust systems (wires or hooks are not acceptable). All staples are loose, broken or missing. There is excessive vibration of the exhaust line. Every part of the exhaust system passes through the passenger compartment. The exhaust pipe is broken, trapped or eroded to such an extent that exhaust gases can enter the interior of the passenger compartment. The exhaust pipe cannot discharge the exhaust from the rear or sides or from the top of the passenger compartment of the vehicle. NOTE: Holes in the exhaust system made by the manufacturer for drainage are not grounds for release. The exhaust system has been removed.
The exhaust system was turned off. The catalytic converter was removed, leaked or disconnected on a vehicle model from 1984 onwards. The exhaust system has been modified in one way or another to make it ineffective. I don`t think it`s legal. I run the X pipe and Roush exhaust and it`s very noisy. Honestly, I can`t imagine having anything stronger. 1. Texas State inspectors inspect the exhaust system for holes, leaks, or plates on the muffler, resonators, exhaust pipe, exhaust pipe, or catalytic converter.2. Every motor vehicle must be permanently equipped with a properly functioning and continuously functioning silencer. 3. The exhaust pipe should omit exhaust gases at the rear or sides of the „passenger compartment“ and should not be in a position where exhaust gases could enter the passenger compartment.
Some pickups are equipped with a motorhome lid or hard shell, this truck modification is considered a passenger compartment. The entire structure of a motorhome is considered a passenger compartment.4. Dual silencing systems may be converted to single silencing systems and individual silencing systems to dual exhaust systems, provided that the modification does not comply with the requirements for exhaust emission systems. 5. Government inspectors do not check the noise level of your exhaust system, only that it is present, in good condition and functional. However, some Texas cities and counties have „noisy“ exhaust ordinances and you could be arrested, perhaps even with a ticket. See „Noise and Volume“ below for more information on noisy exhausts. Texas` emission standards for mufflers are designed to reduce the levels of hydrocarbons and carbon monoxide released into the atmosphere. By eliminating malfunctions of the exhaust system, harmful emissions are avoided. A silencer and its adjacent parts, e.g.
Exhaust pipes, resonators and catalytic converters must not show cracks, leaks or locations. The law states that the silencer must not be punctured. Even if a perforated muffler has been repaired, Texas law requires the vehicle owner to replace it with a new muffler. Vehicles equipped with mufflers that do not meet these standards may be cited by police or fail a vehicle inspection. If you live in Texas or plan to move to the state, you should be aware of the modified vehicle laws. Below is information you can use to ensure that your modified car or truck is considered road legal when driving on Texas roads and highways. Texas offers a variety of old and classic license plates: road poles are those made before 1949 or appear to have been made before 1949.
