Do Exhaust Tips Make Cars Louder?

Can exhaust tips make your car louder and if so, how will it sound? Here's a definitive guide that answers this exact question.

So, you want your car to be a bit louder? Well, there’s one affordable (ish) way to go about it: a new, specialized exhaust tip.

Resonating exhaust tips alter the noise your car makes, increasing the volume. They also decrease the pitch, giving your compact-engined vehicle that James Earl Jones rumble.

This guide will address exhaust tips. While they’re an inexpensive way to modify your car (to a limited extent), there are certain things you should know. These include how the sound changes, the legalities of using them, and how much they cost.

I’m prepared to help you with changing a maximum of 2 adjectives in the text you provide. Please share the text you’d like me to modify, and I’ll follow your instructions precisely.

What Is An Exhaust Tip?

No rewards for correct guesses here. Exhaust tips fit onto the end of your exhaust – the ‘terminus.’

Adding a tip changes the sound and, to an almost undetectable effect, the exhaust gas flow.

They’re constructed using diverse materials, including steel and carbon fiber. The shape, bore, material, and overall layout all influence the resulting sound.

Exhaust tips are a popular choice for anyone wanting to modify their car without spending too much money. They won’t have any substantial impact on your vehicle’s performance. However, they can produce a splendid noise.

Do you think your automobile could do with an exhaust tip? Read on before deciding!

Do Exhaust Tips Make Cars Louder?

Hearing Click Sound

Do you want to enhance the sound your vehicle makes? Okay. So, does an exhaust tip make your car louder?

In short, yes. They can, at least. Resonating exhaust tips are usually specifically engineered to make your car sound more forceful.

They’re created in specific shapes and using meticulously selected materials. When these reverberate as the exhaust gases pass through. It’ll sound quite different from your original!

What Kind Of Noise Do Exhaust Tips Make?

Exhaust Tips

This is a somewhat ambiguous query. It’s kind of like asking, “What sound does a wind instrument produce?”

In wind instruments, the sound is always produced in the same way: airflow causes vibrations. But each instrument is distinct. A clarinet, a flute, a saxophone, and a tuba sound nothing alike.

The exhaust tips are also subject to the identical principle. The final sound is determined by the shape, size, and material used.

If you want a better idea of the exact noise an exhaust tip makes, look for videos or audio clips of it. Ideally, it should be attached to the same make and model you have. If not, you can expect something similar, at least.

Do Bigger Exhaust Tips Mean A Louder Noise?

Does a larger exhaust tip mean a louder exhaust tip? Well, yes, in general. But not always.

Note: in engineering, “bore” refers to the inner diameter of a cylindrical shape. So, an exhaust pipe’s bore its inside diameter.

The bigger the exhaust tip is, the more the hot exhaust gases slow down (the flow rate reduces). As they do this, they expand into the space. This typically creates a noisier sound.

For example, consider a small sedan or hatchback and its minuscule exhaust. It doesn’t make any kind of thrilling noise, right? Now, look at the back of a 2005 Impreza WRX STi. Notice a difference?

It’s crucial to note the words “in general” and “usually.” It’s not always true to say that bigger equals louder. It depends heavily on the shape and material, too.

The overall noise your car makes depends on a few elements, including:

  • Engine size
  • Engine speed (“revs” or “rpm”)
  • Exhaust system design (including whether you have a sports exhaust replacement)
  • Catalytic converter efficiency
  • Muffler design and type
  • ECU settings, chips, re-tunes, etc.
  • Road noise
  • Other rattles (suspension, engine mounts, etc.)

If you buy and install a resonating exhaust tip, it’ll add to and modify these noises somewhat. But you’ll need to address each of these elements to see more substantial changes.

Are Exhaust Tips Legal?

Buying a car

Exhaust tips themselves are absolutely legal, especially if they decrease the noise your car makes. But that’s not why you’re reading this page, is it?

In the US, it depends on which state you reside in. Learn more about the noise laws in each state by following this link.

In general, you can’t bypass a muffler. That’s acceptable in terms of exhaust tips since they’re installed after this.

Notably, you can’t drive a car emitting “unusual or excessive” sounds. Some states even have specific noise limits – a set number of decibels – and you’ll be in hot water if your car’s louder than this.

There could be regulations about making noise at night. If you drive your car at night and it’s too loud, your neighbors might be disturbed when you arrive home. It’s not very thoughtful.

Finally, a prominent exhaust tip invites law enforcement to pull you over. The bold, non-subtle types do look suspicious. Police officers are well within their rights to check you out, and you might get a ticket.

So, yes – they’re lawful. But don’t go too extreme. You’ll be asking for trouble.

Do Exhaust Tips Bring Any Kind Of Performance Upgrade?

High Performance

No. Your vehicle will behave in exactly the same manner as before.

There might be a slight, slight change in horsepower. This comes from marginally improved gas flow at the exhaust tip. But it’ll make such trivial difference that you won’t notice a thing.

As a point of reference, a top-quality performance exhaust – the complete system – has the potential to boost performance by as much as 10%. As much as. This necessitates other modifications to the engine, ECU, and brakes, at the very least.

An exhaust tip is a segment of a performance exhaust. It’s also at the very end of the pipes, meaning it really doesn’t influence the gas flow in any substantial way.

Having said that, you might feel like you’re going faster. You aren’t, but the louder noise can give this impression. And if you’re having a little more fun but still going the same speed, then why not?

How Do You Attach Exhaust Tips?

Attaching Exhaust Tips

First, you must ensure the exhaust tip you buy fits your car. Before buying one, check the fit. For the greatest accuracy, look through online forums. You’ll no doubt find someone that’s attached an exhaust tip to your precise make and model before.

Collect your options and then narrow them down. Use factors like noise level, sound (YouTube!), and budget.

Some performance parts stores will allow you to enter your make and model. That way, you can be sure it fits.

Finally, it’s worth measuring the bore and total diameter of your tailpipe/muffler tip. Compare this to the product specification of the item you’re buying. It should be the same or very comparable.

When you have one, simply follow the instructions to attach it to your car. It should come with a series of sleeves or fasteners (or both). Check the package includes these before you purchase them.

It’s then as straightforward as connecting it and tightening it up. And there you have it!

How Much Do Exhaust Tips Cost?

Man Counting Money

Exhaust tips aren’t that costly. Basic ones should cost up to $100, although the majority are $30 to $60.

You’ll most likely be able to attach exhaust tips yourself (see above). If you’re unsure or concerned about it falling off, ask a mechanic to fit it for you. It should take them a matter of minutes, so you shouldn’t expect to pay more than $20 for labor.

This brings your potential total cost to $50 to $80, but most likely less.

Why Exhaust Tips Are Fun… But Relatively Meaningless

Resonating exhaust tips look marvelous and can sound great, too. But they’re a purely aesthetic upgrade to your car. Nothing more.

More substantial performance upgrades that also make your car louder include:

  • Performance exhausts
  • Stage 1 ECU tuning or chips (Stage 2 is a maybe, Stage 3 is a no-no – lots of power but probably illegal and will destroy your engine)
  • Cleaning your engine – removing carbon deposits will help it sound better. Use fuel additives or pay for a rebuild if you have the money.
  • Cleaning your exhaust – again, cleaning the carbon out will help increase the noise.
  • Engine swap – engine swaps are a little unnecessary. Buy a better car; it’ll be cheaper in the long run. However, a bigger engine would produce much more noise. You just have to somehow fit it in your vehicle.

So, if you want to buy exhaust tips to make your car noisier, go ahead. They’ll do just that.

But if you want to increase your car’s bite along with its bark? You’ll need something more… hardcore.
