We service Audi, BMW, Mercedes, Porsche, or any other vehicle you drive. This is done with top-quality equipment at our state-of-the-art facility in San Clemente CA. You'll get the right automotive repair for your engine and muffler system without the extra money you pay at a dealer 💰

DIY Emission & Engine Services

DIY DIFFICULTY is low to diagnose a muffler problem, but high to have exhaust components replaced.


The trouble could be a fuel mixture, engine burn, or catalytic converter issue. It might also be some annoying street noise from the muffler unit that can be solved with a simple pressure washer.


Experienced do-it-yourselfers could diagnose the job and determine at what point they should repair or replace the car part. But those servicing skills take some serious expertise.


That's why customers need a reliable professional to properly identify the right auto repair service.


We do repairs such as:

  • New tires & Brakes.
  • Inspection Diagnostics.
  • Oil changes and fuel system.
  • Check engine light repair services.
  • Mufflers & clogged catalytic converter.


Our team of technicians have the expertise to efficiently fix whatever you need.

How the Car Engine & Exhaust Works

Emission services can seem daunting without auto repair expertise.


Understanding a vehicles fuel, power & gas elimination system:

  • CAR ENGINE: There's a whole service page on this subject for our customers. But, on a basic auto repair level, fuel is sucked into each cylinder... then ignited with fumes being pushed out.
  • EXHAUST MANIFOLD: Used fuel leaves the engine as hot vapor and hazardous gas. It then begins a process of safely being funneled out of our vehicle through insulated pipes.
  • CATALYTIC CONVERTER: The gas emissions enter a catalytic converter to undergo a vital oxidation process. An assortment of metal filters convert noxious gas into better quality air.
  • MUFFLER: Lastly, this sound dampening device maximizes the outflow of fumes from our vehicles and lowers the engine noise. Our car goes from a loud roar... to the soft purr we're used to.


Auto repairs can be a complicated process for the engine, catalytic converter and emission components. The job of our business is to complete a full inspection, diagnose the problem, and service whatever your vehicle needs.

Car Repair Cost for Broken or Rusty Parts

Six Common Automotive Repair Problems and Solutions:


  1. Exhaust Manifold - This connects our engine to the emissions system. If the gasket leaks, hot gas will melt plastic components in our engine bay. This smells like a bad oil burn.
  2. Emission Sensors - Cars are operated by sensors. RSC Automotive Repair can determine if a faulty sensor is setting off the check engine light for our engine or catalytic converter.
  3. Clogged Catalytic Converter - Dangerous toxins are removed by the catalytic converter. Metals used for filtering can clog the unit and produce rotten egg or ammonia smells.
  4. Precious Metal Thieves - Platinum, rhodium & palladium are expensive catalytic converter parts. The converter is stolen for its high street value that runs $2000+ to be replaced.
  5. Broken/Blocked Exhaust Pipe - Drivers back into objects damaging a muffler or tailpipe. We can do those repairs and install new brackets to replace loose (rattling) ones.
  6. Rusty Emissions Equipment - Hot water sitting in exhausting system too long causes corrosion. Trips over 20 miles burn up that moisture thru the process of evaporation.

Evolution of the Engine, Catalytic Converter & Car Muffler

 🕰️

Innovative car and catalytic converter strategies for better quality air:


  • 1966 CA set the first vehicle tailpipe pollution standards in our nation.
  • Congress did us all a service in 1970 by passing a federal Clean Air Act.
  • NOx added to earlier car hydrocarbon & carbon monoxide laws in 1971.
  • This nitrogen oxide (NOx) law led to creation of a catalytic converter.
  • 1982 emissions law for particulate matter from diesel-fueled vehicles.
  • On-Board Diagnostics in 1988 improved engine and car emissions.
  • 1990 car-maker regulations for Zero-Emission Vehicles (ZEV's).


California had the cleanest fuel and vehicles in the world by 1990. High burn fuel for family cars + low emission diesel fuel for the commercial truck/bus vehicles in our business sector.


The Advanced Clean Cars Program of 2012 reduced greenhouse gas emissions even further!


California’s prolific growth, car travel, and street traffic still produce smog problems... BUT we're not the worst in the country like back in 1967. New vehicle improvements need to continue happening though.


Our awesome automotive repair customers—here in San Clemente & beyond—deserve cleaner skies to enjoy and breath to breathe. Whether for us, friends, or future generations… We all deserve a healthier planet as well as better quality life!

DIY Catalytic Converter Cleaning

As auto repair experts, we suggest professional support to fix a clogged catalytic converter. But, there are catalytic converter cleaning solutions that can "reset" a sluggish catalytic converter.


To repair larger blockages—without paying BIG money to have a converter replaced—requires the removal of a clogged catalytic converter. It's NOT easy, though, to crawl underneath a car or truck and take out those rusty bolts.


The next service step is a messy process of using the  SOFT pressure washer setting to spray out the black (oil burn) gunk. REMEMBER: Don't do this on the street and be careful not to damage any engine components.
