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 John's Garage we know this is true. A clogged catalytic converter will eventually affect the performance of your vehicle in Warner Robins, Houston County, Robins Air Force Base and Bonaire. 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 Our Customers Say

Warner Robins, GA

While traveling through Georgia on a Saturday afternoon our travel trailer blew a wheel bearing and we were stranded on I-75. We called many local shops only to be told that they were either closing for the weekend shortly or they could help us later next week. Keith was recommended to us by one RV shop. We called him and he agreed to take a look at it and gave us the address for John's Garage. Keith showed up at 10:30 pm after finishing with another job. He spent about an hour assessing and removing the hub and all the damaged parts. He informed us that he could repair it and would pick up the parts on Sunday morning from his parts supplier. He called mid morning to let us know that his parts supplier did not have the parts available but that they had been ordered on would arrive on Monday morning. He arrived with the parts on Monday morning and had us back on the road before noon. My wife had Googled wheel bearing replacements and determined that it would be between $300 and $500. Keith's invoice was exactly in the middle. We drove from Warner Robins/Macon Georgia all the way north of Toronto Canada and did not have an issue with his work. I would highly recommend Keith if you need repairs in and around Macon GA.
