Downpipe in stainless steel

Did you know that not all downpipes are made of stainless steel?

The stock exhaust systems are in most cases made of iron or in rare cases steel (what is commonly called iron is actually mild steel).

A standard system is hardly ever made of stainless steel due to the cost of the material. In fact, stainless steel is reserved only for aftermarket exhaust systems that have higher prices.

If you doubt this statement and are convinced that your car has a stainless steel exhaust I recommend you put it on a bridge and look at the exhaust line, you will immediately see at a glance that it is all completely oxidized.

On cars of an important level, the exhaust is made with a good steel and oxidation is very slow, on cheap cars the times are shortened and you can find yourself after a few years already with the perforated muffler.

But why are we telling you all this?

Because the material with which the exhaust system or its components is made is important and affects the price and duration as well as the sound.

Given that the performances do not change, the exact same system if made of simple steel or stainless steel has the same performance, the sound instead changes, like its life, which gets longer and finally, the price, which increases.

In fact, stainless steel is a more expensive material.

Inside the steel alloy other components (mainly chromium) are "mixed" which prevent the metal from oxidizing.

A stainless steel drain has a very long life, its oxidation resistance characteristics make it practically immune to holes and cracks.

This higher quality translates into higher material cost, often 100% higher.

The choice of InoxPower (not surprisingly INOX) is categorical, and plans to produce ONLY INOX downpipes even if the costs are higher.

A philosophy now rare to find, given that companies usually tend to make cheap products, not quality products.

We aim for other goals.

We make Downpipes for cars that on average cost € 50 / € 70,000, and we absolutely do not want them to be installed on these cars for 4 pennies.

Those looking for maximum savings do not find it with us.

This is why we do not make de-catalysts for all cars.

In fact, our downpipes have behind them, before marketing, an important study, we waste time to do simulated and real tests, to create precise templates, we work with many preparers and this makes our level very high and we will certainly not lower it to sell some exhaust in more.

The sound also changes

Yes, the sound changes with the use of stainless steel.

If you think that it is the last part of the exhaust that makes the difference in sound, unfortunately you are wrong.

This rule applied to cars of yesteryear, where the silencer was the only part of the exhaust that attenuated the sound.

Fitting a sports silencer guaranteed you to get a breathtaking sound.

Modern cars have several "caps" and the final silencer is only partly responsible for the sound emitted.

Of course, changing it a little changes the sound, but the real revolution, the real leap in quality, comes by changing the downpipe with a DECAT.

We talk more about this aspect HERE, now without dwelling too much, what you need to know in this in-depth analysis is that a stainless steel dowpipe "sounds" differently from an iron or NON stainless steel dowpipe.

Stainless steel has another stamp, this is due to the percentage of carbon present in the various alloys, which makes the material resonate or not.

In the end it is about vibrations that turn into sound (for many it is noise, for us enthusiasts sound :)) and the sounding board that transmits these vibrations makes the difference.

The stainless steel "sings" better and conveys a better tone.

We understand that saving 100/200 euros for a Chinese or low-quality downpipe can be tempting but you must be aware that quality and materials are paid for.

The downpipe is a fairly stressed component, especially when we are above 350/400 hp.

It is subjected to continuous thermal stress and constant vibrations, a mix that can cause cracks.

From experience we can assure you that it is not a rare occurrence to have the downpipe mounted on the machine with small cracks.

In this case, the least that can happen to you is that your car has a steady decline in performance, instead of running with 500 hp maybe running with 450.

So you eat the power, in practice you think you have a certain amount of power but you find yourself with a perennial decrease in CV, you do not realize it because in practice you never have the maximum power.

In the worst case, however, you have a sharp drop in power and the car goes into recovery in a more or less "protective" way.

If all goes well you come home stunning everyone with a sound that not even a Formula 1 emits, if it goes wrong you leave the car there and call the wrecker because it doesn't move.

Now tell me, is it worth it for a few extra bucks to save on the downpipe?

Listen to me, take the hub caps and stickers from china, but not the mechanical components.

InoxPower's downpipes have a guarantee on cracks (unfortunately no one is exempt), but if something happens we will send you a new Downpipe at no cost to you.

What other companies give you this guarantee?
