Some important notes to keep in mind about Texas` exhaust system laws are as follows: You can`t switch from a single exhaust to a dual exhaust or vice versa, except in certain circumstances. You can add a dual exhaust if your vehicle manufacturer has designed your vehicle`s make and model for a dual-exhaust version. In other words, you can`t just attach a double exhaust to each vehicle, even if you install two catalytic converters in the system. A dual exhaust on a chassis designed for a single inverter affects emission performance and can result in a failed inspection. Holes, leaks or stains on the muffler, resonators, exhaust pipe, exhaust pipe or catalytic converter. The vehicle is not equipped with a silencer. Any connection is loose or leaked, including distributors. Contains no minor leaks on the exhaust gas control valve (manifold damper or heat riser). The dispenser is torn or broken, causing leaks. The exhaust system is not attached to the vehicle by mounting brackets for exhaust systems (a wire or hanger is not acceptable). All supports are loose, broken or missing. There are excessive vibrations of the exhaust pipe.
Every part of the exhaust system runs 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 does not discharge the exhaust from the rear, sides or top of the passenger compartment of the vehicle. NOTE: Holes in the exhaust system made by the manufacturer for drainage are not grounds for refusal. The exhaust system has been removed. The exhaust system has been decoupled. The catalytic converter was removed, leaked or disconnected on a vehicle of the 1984 or later model. The exhaust system has been modified in one way or another to make it inefficient. Texas regulates motor vehicles to ensure that vehicles can safely travel on public roads.
Regulation and monitoring extend to vehicle exhaust systems. Texas is unique in that, unlike most states, it does not prohibit a specific decibel level in terms of vehicle exhaust systems. Although there are no specific decibel levels, Texas regulates the properties of the exhaust system. While you may be considering changing your car`s exhaust system, it`s important to know that all vehicles must be equipped with a muffler. Cuts, bypasses or similar devices are prohibited. Aftermarket exhaust modifications are allowed as long as they are not too noisy, but Texas state laws do not set a decibel limit. Unlike other states that impose a decibel limit on noise generated by exhaust systems, Texas does not have a decibel law. However, the Texas Transporation Code states: “A motor vehicle must be equipped with a working muffler that operates continuously to avoid excessive or unusual noise.” The exhaust system of your car or truck is finely tuned to meet the best requirements for performance, sound and emissions. Many people like to make changes to their exhaust system to reduce back pressure and improve performance and performance. Texas State Inspectors FAIL Exhaust System for: Is My Exhaust Too Noisy? The answer we all know is subjective.
Some of us like our vehicles to be quiet, others like it loudly and all the gaps in between. While you may think your vehicle sounds good and isn`t too loud, a neighbor`s definition of “loud” can vary greatly. Don`t worry, we think it sounds good too!! However, some counties and cities have their own regulations against noise levels in dB (decibels). The state of Texas doesn`t regulate exhaust noise levels, but you should look for ordinances that apply in your city or county. That being said, most of us don`t have noise meters or dBs with us, and most law enforcement officers probably don`t either, so it`s the opinion of a complainant or law enforcement officer that matters in many cases. Some cities are tougher on noisy exhausts, others don`t care so much, it`s up to you to make your best judgment on how “too strong” is for your place of residence and work. Car modifications allowed in other states may not be legal here in the state of Texas. It is important to know what changes are legal if you leave another state or before coming to the detriment of customization. The state of Texas has laws that regulate the noise limit your vehicle can produce.
Many car enthusiasts choose to modify their car`s exhaust system, so it`s important to know the laws about exhaust noise. The following section describes the relevant laws and laws relating to car exhaust noise laws in Texas. Any changes to the exhaust system of Texas-registered vehicles must not produce “excessive or unusual” noise. Non-reflective tint is allowed on the windshield above the as-1 line specified by the manufacturer or the top five inches.
