Exhaust Related FAQs
What is a rough idle?
A rough idle describes a vehicle's engine with spark plugs that are not firing correctly when the vehicle is in park, with no gas applied. Most vehicles idle between 600 and 1,200 RPM and should hold their idle speed consistently.
Can you put any exhaust on any car?
Not every exhaust will fit every car. Compatibility isn't just about car make and model; engine specs, optional extras, and even trim levels can influence the fit. Make sure you consider not just the make and model, but also engine details, fancy extras, and even trim levels before getting your heart set on a shiny new system.
Why is smoke coming out of my tailpipe?
The most common reason for thick smoke coming out of your car's exhaust pipe is the fuel to air ratio in your engine is too rich. This means that the fuel injectors are either adding too much fuel or that the intake valves aren't letting enough air in. This is caused by a cracked or leaking fuel injector, a failing O2 sensor, or air filter that needs replacing.
Catalytic Converter FAQs
Can I drive with the catalytic converter light on?
A bad catalytic converter can increase your car's exhaust emissions, but it does not prevent you from driving. At RST Automotive Inc. we know this is true. A clogged catalytic converter will eventually affect the performance of your vehicle in Fremont, Union City, Newark and Milpitas. Exhaust gases will not escape easily and create an increase in exhaust gas pressure. The buildup in pressure can lead to high-cost repair bills in the future.
What can cause a catalytic converter light to come on?
A catalytic converter helps reduce harmful engine emissions from entering the air by breaking down the harmful byproduct of internal combustion into less-harmful compounds. If your catalytic converter isn't working properly the check engine light will come on. The most common causes for a catalytic convert warning light to display are a clogged, cracked or melted converter. Sometimes the problem isn't the catalytic converter at all but an exhaust leak letting gases out of the system before it reaches the converter.
What happens to your car after the catalytic converter gets taken?
Removing the catalytic converter has a dramatic impact on your vehicle's acoustics. A deep, loud roar replaces the engine's usual hum, intensifying as you accelerate. Additionally, expect rough transitions and sputtering sounds when shifting gears, indicating impaired performance and potential engine damage.

What People Say About Us
I Brought my car in for an oil change. There was a light on the dash panel that I thought was just a reminder to change the oil. Turns out that it was Nissan's version of the check engine light. Roger and his team were able to diagnose the issue and clear the light. Always great service at RST!
I'd have to say after dealing with multiple mechanics in the tri-cities area that, hands down Roger is by far the most honest and professional mechanic I've dealt with to date, I'll be upgrading my 1971 corvette from a Muncie 4 speed to a Tremec 5-speed soon, I'll be contacting Roger again in the near future, to handle this project for me, I can count on his work, and he has the integrity to stand behind his work! Kudos to Roger and the RST staff!!

I brought my recently acquired American Clipper motor home in to have the coolant system flushed and the chassis lube. Roger took care of my needs on my old motor home and I want to continue to get the same service I have come to expect.
Thank you Roger & Jamie for providing excellent service! Our catalytic converter was stolen from our beloved RV. One of my tenants recommended us to them. Our CC was discontinued, but I was able to find a compatible one. Roger ordered it, delivered next day. We brought our RV in, and it was installed, caged. Not only that, we got it smog checked also. All in 1 DAY!! Thank you for helping us out, and providing speedy service. We will definitely will be back again for service on our RV! Thank-you!
I recommend Roger. He is an excellent mechanic and he does specialize in older cars which is what I have so that's helpful for me as well. Prices tend to be on the more expensive side, but with the older car I previously had, he was one of the few who could fix it.
RST has taken care of my truck since it was born. I trust no one else to work on the truck. When they tell me my vehicle is safe and running well, I feel so secure. I am 84 years old and safe and secure is a MUST. 5 stars does not seem enough.
