Exhaust Laws..Turbo Cars come in Hey guys, I have searched for a while and cannot find out how yall are getting away with exhaust systems without any muffler. How are yall guys passing inspection with no muffler and also downpipes that do not go all the way back??
I am to the point to where I am doing my exhaust setup and honestly if I could get away with it I would prefer going out the side bumper or mid chassis running 3.5inch.

You could take it to a seedy shop on the wrong side of town where they slap stickers on for an extra 20$...But, I hear SRT-4s came from the factory without a muffler.
EDIT: OEM SRT-4 exhaust on right, aftermarket side exit on left.

I tried that one time and when I went to a place and he found I didnt have any cats they "red flagged" me. They said it keeps me in the system showing why i failed and keeps me from just going down the road. I had to install my old y-pipe to get it inspected then switch when I got home

I called STS about their turbos a while back when I had my corvette and never got a straight answer. In their system the turbo takes the place of the muffler. I called round the Texas DPS offices and got a bunch of BS answers as well. That is why I never bought from STS. Good luck with your search.

Actually it does say a vehicle has to have a muffler and it has to maintain a proper decibal level. The muffler has to be like new with no holes or even patched holes. If it does it has to be replaced with a new one. It also can not be bypassed. However there is not a specific decibal level to maintain. It just says something to the tune of "a proper level that is expected on a normal vehicle" or something like that. When I get home I will look it up again in my computer and post it. All in all sounds like I need a "friend" to help pass

20.15 Exhaust System. Every motor vehicle shall at all times be equipped with muffler in good working order and in constant operation.
Muffler defined: Muffler is a device consisting of a series of chambers or baffle plates or other mechanical design for the purpose of receiving exhaust gas from an internal combustion engine and/or turbine wheels for the purpose of receiving exhaust gas from a diesel engine, both of which are effective in reducing noise.
The exhaust system includes the manifolds, gaskets, exhaust lines, mufflers, resonators, tailpiping, and supporting hardware.
Motor vehicles cannot be equipped with a muffler which is perforated or which was perforated and has been repaired, either by a muffler repair jacket or by patching or in any other way. In those cases where a muffler is perforated at the time of an inspection or has been perforated and has been repaired previous to the inspection, the muffler must be replaced or the vehicle rejected.
Some pickups are equipped with a camper or hard shell cover and are sometimes used for the transportation of passengers. The tailpipe should discharge the exhaust at the rear or sides. This truck modification will be considered as a passenger compartment.
The entire structure of a motor home-type vehicle is considered a passenger compartment. The cab only of all other truck-type vehicles is considered passenger or luggage compartment.
If the vehicle is equipped with lake pipes or similar devices, such pipes or devices must be securely plated and bolted or capped.
Dual exhaust systems may be modified to single exhaust systems and single exhaust systems to dual exhaust systems, provided the modification does not violate requirements concerning exhaust emission systems.
The catalytic converter will be considered as a part of the exhaust system on all vehicles prior to 1984 year model and will be inspected only visually (if present) for leakage. On 1984 and later model light truck and passenger vehicles, the catalytic converter will be checked for presence and leakage. Flexible tubing which meets the requirements listed below may be used anywhere in the exhaust system.

Its saying either one of those constitutes as a muffler. A turbo is consider a noise suppression device in the State of Texas. It's 100% legal to drive a Gas or Diesel-motor vehicle without a muffler, if it is turbo equipped and is emission compliant.

So bottom line...you either have a turbo or a muffler to pass?
I've never had a turbo and its been years since I've had a muffler and have always passed inspection at a regular shop. How is that?
This year will be a different story. New headers and straight pipe. Way above the 'acceptable' decibel level for sure.
