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 Northridge Auto Repair Technicians we know this is true. A clogged catalytic converter will eventually affect the performance of your vehicle in Northridge, Glendale, Pasadena and Downey. 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.

Art is your go-to trusted expert and a rare, extraordinary genius, kind and funny mechanic!! Very lucky to have met Art and have his outstanding help to resolve all my issues on my older vehicle that had several serious electrical problems (parasitic drain, instrument clusters on dash no longer working, and my driver seat button no longer worked) that no one else could help me solve!! Art is so smart and hardworking! Art is also very quick to get the work done especially considering older vehicle parts are very difficult to find, and yet Art kindly charges a very reasonable price. Art also replaced my badly leaking radiator thanks to him for carefully noticing this before I had an issue! Art was well worth the further distance I had to drive to but worth every mile! Art is very much loved and appreciated! Thank you so very much Art and for taking such amazing care of me!! :) You are the Best!
