Catalytic converter delete pipe

I deleted the converter on my Formula for a while and after the novelty wore off - about three days later - I couldn't stand it. Mine sounds fantastic without it. I get a awesome burbule and screaming rumble with it off. If you use "straight pipe", whenever you let off the gas, you'll have "burbling" alot of Backfiring it'll sound more like an old truck.

Don't glass packs eventually were out? I dont know about now, but in the old days they were packed with course grade steelwool. We would install them, fill them up with water and let it set overnite. In a day or two they sounded great. Out in the I really like the way it sounds. Of course, the big cam and the headers help, too. Praise the Lowered! The sound is great for both idle and high revolution! I have a tendancy to run with the school of thought of no cat myself. Which are the superior headers 2.

What is the best solution in the spot the CAT lived in? What is the superior exhaust system? I would assume some companies headers, some sort or 2" pipe, and a Borla Exhaust.

I would like to know what kind of horsepower and torque would be gained with a setup like that, assuming everything else on the engine is stock. Thanks Seeking a Fiero, preferably a GT and automatic. A clogged catalytic converter is another story but in all honestly other then just being a cheap skate theres no reason at all to delete your catalytic converters.

Catalytic converters being so awful for performance is a myth that needs to die about as much as the lotus suspension crock.

Arn I think your looking at it from a weird "perspective". I'm not suggesting that he "ADD" a catalytic converter to "improve" low-end torque.

I am suggesting that he maintains a catalytic converter a newer, larger CFM rated one to "maintain" the low-end torque. You WILL see a power gain by eliminating the stock catalytic converter on the Fiero, however, if you took two stock automatic Fieros everything identical I guarantee to you that the one with the "high flow" cat will win in the quarter mile.

Removing a cat on the Fiero will reduce restriction, but there's a lot to consider. The Fiero's V6 is a decent motor It was NOT designed for high-rpm driving.

When they designed the exhaust system, they designed it taking everything into consideration. IE: the size of the exhuast piping was determined while looking at the total aspect of the exhaust including the catalytic converter and the muffler.

Everythig is designed to match. There is the concern that the fumes from your exhaust could reach the vehicle cabin too. It may do more than induce a headache. It could create life-threatening situations in some circumstances. You will create more noise when you drive. Although the sound of an engine which is not held back by a catalytic converter sounds healthy, it can also become unhealthy from a noise perspective. If you have the windows down and the engine full, you might exceed decibels without this device.

Any noise above 85 decibels is potentially dangerous to your hearing health. See above. You may use more fuel without a catalytic converter. The catalytic converter does more than convert harmful gas into something less dangerous. It also squeezes a better fuel economy out of some vehicles. However, some people have reported that once they remove this device, they discover that their miles or kilometers per gallon actually go down.

The most common explanation seems to be that they are burning more gas because their O2 sensors are not reading correctly and therefore requiring more fuel usage. Relatedly, there are reports that a notable amount of backpressure is lost. If your vehicle must go through an emissions test, then it is essential to remember that there is a visual test in addition to the performance evaluate. Testers are usually required by law to report failures like this, which means an uncomfortable conversation will be waiting for you when you try to drive away.

A failure may cause your vehicle to be impounded too. You will lose your low-end torque without a catalytic converter. The catalytic converters in the past were very restrictive because the exhaust coming from the combustion process was extremely toxic. Catalytic converters are standard for most vehicles in most states. It is one of, if not the, most important parts of a car to make battle with ever stringent emissions standards.

Cat-converters turn hazardous toxins into harmless gases. However, because factory catalytic converters make nice with emissions standards, it causes some backpressure which limits your engine to produce more horsepower thus, hindering performance.

A test pipe is the section of piping in an exhaust where the catalytic converter is. Removing the catalytic converter creates much higher exhaust flow. For turbocharged cars, this results in less back pressure and better flow for the turbine. Test pipes or, cat delete pipes, or straight pipes, do not contain a catalytic converter. The only solution is to bring the car back to factory specs and pass the inspection. Make sure you research the laws in your area thoroughly before you perform this mod.

Removing the Catalytic converter will not damage your vehicle as long as you tune it afterward. On the contrary, it can make your engine feel alive by removing the backpressure that is created between the catalytic converter and the exhaust manifolds. There are even cases where 50 horsepower is gained. This can apply to engines that are extremely restrictive like diesel cars.

Diesel cars are not that popular in the USA but the diesel truck is extremely popular, many pickup truck drivers are removing their catalytic converters and running coal. This causes huge pollution, and it is not recommended — you can also get a decent fine from this.

So avoid it! This is just for your info. The benefits of removing catalytic converter are clear — you significantly reduce backpressure and gain horsepower. However, the downsides are also huge.

CAT delete should only be done for race cars that are operating on track. Performing this on a regular street car is not recommended. If you have access to a grinder, I recommend you watch a YouTube video and do it yourself.

You can get the pipe extension from Amazon. Cutting your catalytic converter is going to give you a bunch of horsepower — that is true but you should never do it on a daily street car. What ends up happening is you being forced to put back your CAT and costing additional money or time in the process. If you are serious about making horsepower, you should save up some money and go the proven route of installing turbo or exhausts. Passionate about everything mechanical.
