What is a Catalytic Converter?

A catalytic converter is a vital emission control device in most modern automobile exhaust systems. Its function is to reduce harmful pollutants in exhaust gases before they are released into the atmosphere.

Catalytic converters were introduced in the 1970s to help reduce vehicle emissions and improve air quality. Today, they are a standard feature on all modern vehicles and are required by law in most countries.

How Does a Catalytic Converter Work?

The catalytic converter uses a catalyst, typically a precious metal such as platinum, palladium, or rhodium, to chemically convert harmful pollutants into less toxic substances. The exhaust gases pass over the surface of the catalytic material, which catalyzes (or speeds up) chemical reactions that convert pollutants such as carbon monoxide (CO) and hydrocarbons (HC) into carbon dioxide (CO2) and water (H2O). Nitrogen oxides (NOx) are also reduced to nitrogen and oxygen.

The catalytic converter operates at high temperatures, which is why it is typically positioned close to the engine. The heat generated by the engine and the exhaust gases is enough to activate the catalyst and initiate the conversion process.

When Should You Replace Your Catalytic Converter?

Generally, a catalytic converter can last around ten years before needing replacement. However, if you experience any of the following symptoms, it may be time to replace your catalytic converter so that you can continue driving safely and efficiently without risking further damage to other components in your vehicle.

Decreased fuel efficiency due to clogged airways; 

Damaged or missing heat shields near the exhaust pipes;

Loud, rattling noises coming from under the hood; 

Smoke emitting from the tailpipe or engine compartment; or illumination of a "check engine" light on your dashboard.

FAQs

Inside the catalytic converter, precious metals like platinum and palladium act as catalysts, spurring a chemical reaction that neutralizes nitrogen oxides, hydrocarbons, and carbon monoxide.
Absolutely, as it's essential for legal compliance and vehicle functionality. A failing catalytic converter can result in poor engine performance and even trigger the check engine light.
Cleaning a catalytic converter can sometimes restore function if it's not too far gone, but replacement is often the better option when facing severe damage or clogging. Considering the importance of a catalytic converter in maintaining vehicle performance and emissions standards, replacement is typically the most reliable solution when faced with significant damage.

I'm genuinely impressed with the Suncent Exhaust Header for my E46. The packaging was exceptional—everything arrived securely sealed with zero shipping damage. Fitment was nearly spot-on, though I encountered a couple of minor hurdles. I needed to slightly adjust the engine mount bracket for a perfect fit, which was a quick and easy tweak. Additionally, the O2 bung placement required a minor firewall modification, but this is a common step with most aftermarket headers for the E46 and was straightforward to resolve. One suggestion: I recommend using OEM header gaskets over the ones included in the kit. The OEM gaskets provide a superior seal, better fit, and improved heat protection for the upper plastic valve cover. Overall, I'm thrilled with the headers. They’re a fantastic upgrade for the E46, and despite the small adjustments, the installation was smooth and hassle-free. Great job, Suncent!

I just installed the BMR adjustable motor mounts (MM007) on my 2014 Mustang GT last weekend, they fit after removing an adjustment shim. I bought some heat tape to wrap around some wires/hoses coming from the supercharger. The headers came with the wrong type of bolts. I bought some stainless steel bolts (M10-1.25x20mm). Finally I bought the BBK exhaust flow tube (BBK-14670) so the exhaust shop could connect it to my 3" Roush cat-back exhaust. I went in for the repair on Wednesday and came back with a very strong push back, and the sound was very deep and powerful. I especially liked the popping sound when I pushed the throttle to the bottom, and the meeting was my happiest time. I hope this helps you.

Just installed headers and x-pipe on a 2007 Corvette z06 ls7. I have put on a lot of headers on cars over the years but these were the best fitting ones yet. Real happy.

Ordered the exhaust kit (Long tube headers, x-pipe, etc) for my 2002 C5 Corvette. They arrived this morning and upon unboxxing I was shocked to see everything is there as described. Hardware and gaskets too. They look amazing. Can't wait to install to my hotrod.
