The Exhaust Episode - EP.186
Nissan Skyline
Car

Nissan Skyline

The Nissan Skyline is a performance car made by Nissan. Many owners change the exhaust to change the sound and sometimes the driving feel. The podcast is talking about different exhaust options that people use on Skylines.

Term

exhaust

“Exhaust” is the system that sends engine gases out the back of the car. People notice it because changing it can make the car sound louder or deeper.

Term

wheels

“Wheels” are the rims and tires you see on the outside of the car. People upgrade them because they can change how the car looks right away.

Term

wheel gap

“Wheel gap” is the space between the tire and the fender. Lowering the car usually reduces that gap and changes how the car looks.

Term

low pros

“Low pros” means low-profile tires with a shorter rubber sidewall. They often make the car look lower and can feel a bit more responsive when you turn.

Brand

moteggies

“Moteggies” is a brand of aftermarket wheels. People recognize them because they were common on tuner cars.

Term

muffler shop

A muffler shop is where you go to have an exhaust made or modified for your specific car. They can cut and weld pipes so it fits the way you want.

Term

catbacks

A cat-back is an aftermarket exhaust that goes from the catalytic converter to the back of the car. People buy it because it’s often easier to install than building a custom exhaust from scratch.

Term

crush bent

Crush bending is a way exhaust pipes are bent by squeezing them into shape. It’s common for custom work, but the bend can sometimes restrict flow if it’s not done carefully.

Mitsubishi Eclipse
Car

Mitsubishi Eclipse

The Mitsubishi Eclipse is a sporty Mitsubishi coupe that lots of people modify. Here, the point is that the host couldn’t find an exhaust they liked for their naturally aspirated Eclipse, so they went custom.

Term

NA

NA means naturally aspirated, so the engine makes power without a turbo or supercharger. That can matter because exhaust parts may not fit or may not be available the same way.

Term

EPA

EPA is a U.S. government agency that sets and enforces rules about pollution. Exhaust parts can be restricted because they can affect emissions, so shops worry about breaking those rules.

Term

turbo spooling

Turbo spooling is what happens when you press the gas and the turbo starts spinning faster to make boost. People often love the sound it makes while it’s ramping up.

Term

cold start

A cold start is when you start the car after it’s been off for a while and the engine is still cold. The exhaust often sounds louder or different at first because the engine is running differently while it warms up.

Brand

Nismo

Nismo is Nissan’s performance brand. It makes enthusiast parts like exhausts, and the speaker is saying their car came with one.

Term

downpipe back

“Downpipe back” means the exhaust upgrade runs from the downpipe toward the back of the car. It typically replaces the sections after the downpipe, like the mid-pipe and muffler.

Term

street legal

“Street legal” means the car and its emissions equipment meet the legal requirements to be driven on public roads. In import/inspection contexts, that can determine which exhaust components are installed so the vehicle can pass compliance checks.

Term

tune

A “tune” means changing the car’s computer settings. They’re saying the exhaust by itself won’t do much, but the tune can help the engine use the exhaust better.

Term

turbo outlets back

They’re talking about where the exhaust upgrade starts—right after the turbo. Where you change the exhaust can matter because some restrictions are earlier or later in the system.

Term

without a cat

“Cat” is short for catalytic converter, which helps control exhaust emissions. They’re saying the setup is “without a cat,” which can change exhaust flow and usually requires careful tuning—and it may not be legal for street use.

Civic Type R my EK9
Car

Civic Type R my EK9

The Honda Civic Type R (EK9) is a sporty Civic made for driving enthusiasts. Here, they’re using it to explain how swapping the exhaust can change how the car breathes and how much power you actually feel.

Brand

Mugen header back

Mugen is a performance parts brand that makes upgrades for Hondas. “Header back” means the exhaust upgrade runs from the header all the way back, and they’re using it to show how exhaust changes can improve breathing.

Term

wastegate flap

On a turbo, the wastegate flap is a valve that helps control boost. When it opens, it lets some exhaust go around the turbo so the turbo doesn’t push too much pressure.

Term

elbow

Here “elbow” means the curved pipe right after the turbo that redirects exhaust. If that curve is restrictive, it can slow flow; a better-shaped elbow can help exhaust move more freely.

Term

muffler style

Muffler style refers to the design of the rear exhaust components that shape sound and how the tailpipe looks. Different muffler designs (single vs dual, oval vs round tips, single vs dual mufflers) can change both the visual “stance” and the exhaust note.

Brand

apexi

Apexi is a company that makes aftermarket performance parts, including exhausts. In this discussion, they’re referencing Apexi as an example of a specific dual-tip look.

Person

Reinhard

They mention “Reinhard” as the person who makes a certain exhaust setup. The episode doesn’t say enough for us to know exactly who that is.

Brand

H.A.S.

H.A.S. is mentioned as an aftermarket exhaust brand that made a dual exhaust setup in the past. The speaker doesn’t explain the company in this clip.

Term

dragger

“Dragger” sounds like a specific exhaust product name. They’re saying it used a dual exhaust layout that ran up near the turbo, not just at the back.

Honda Civic
Car

Honda Civic

The Honda Civic is a popular compact car that many people modify. They’re using it as an example of when dual exhaust tips can look overdone.

Nissan Gtr
Car

Nissan Gtr

The Nissan GT-R is a fast, performance-focused sports car. The podcast mentions the “32 GTR,” which is a specific older generation of the GT-R. They’re basically saying it’s the kind of car people treat as special or acceptable.

Toyota Supra
Car

Toyota Supra

The Toyota Supra is a sports car designed for faster driving and a more exciting feel than a normal car. People often modify the exhaust to change the sound and performance. The podcast is mentioning a specific exhaust-related detail on a Supra.

Brand

Tomei

Tomei is a company that makes aftermarket performance parts, including exhausts. The host is saying they’ve had a titanium exhaust from Tomei.

Term

twin loop design

“Twin loop” is a way of routing the exhaust pipes so they make two loop-like shapes. People talk about it because it can change the look and sometimes the sound compared with a more basic exhaust layout.

Honda Fits
Car

Honda Fits

The Honda Fit EV is a small Honda Fit that runs on electricity instead of gasoline. The podcast is mentioning a particular design feature that was included from the factory on early versions. It’s basically talking about how that electric Fit looked or was set up.

Term

oval sport style muffler

This is an exhaust muffler with an oval-shaped outlet. It’s partly about the look, but muffler shape and design can also affect the sound.

Brand

HKS

HKS is a well-known Japanese company that makes performance parts, especially exhausts. The host is comparing their exhaust to an HKS one to judge how similar it feels and sounds.

Brand

super turbo

“Super Turbo” is the name of an HKS exhaust style. Different exhaust models from the same brand can sound different, so the name helps enthusiasts identify the exact setup.

Term

straight piped

“Straight piped” means the exhaust is set up with little or no muffling. That usually makes the car much louder and changes the sound a lot.

Brand

buddy club spec to

Buddy Club is an aftermarket parts brand. “Spec to” sounds like a specific exhaust version, and the speaker is saying it’s very loud/extreme compared with more normal exhausts.

Term

four inch straight pipe tube

“Four inch” means the exhaust pipe is very wide. A wide, straight pipe with little muffling usually makes the car louder and more obnoxious-sounding.

Term

boom tube

“Boom tube” is slang for an exhaust that sounds extra boomy—more bassy and resonant than refined. It’s the kind of sound that can be fun at first but gets tiring.

Term

slip fit

“Slip fit” means the exhaust pieces connect by sliding together. Because the exhaust gets really hot and moves a bit, this kind of connection can flex without breaking. It’s a common way to keep the exhaust from stressing the car.

Term

silencer

A “silencer” is an exhaust piece meant to reduce how loud it is. People use them to make an aggressive exhaust more livable for daily driving. It can also change the sound character, not just the volume.

Term

GTRs

“GTRs” means Nissan GT-R cars. People often upgrade the exhaust on these cars, and the sound is a big part of the discussion. Here they’re comparing exhaust brands for GT-Rs.

Brand

Nizmo

“Nizmo” is being mentioned as another exhaust option people compare against HKS. The hosts are basically asking what makes one exhaust sound better than the other. It’s a brand-versus-brand debate about exhaust tone.

Term

3 and a half inch from the outlets to the muffler

They’re measuring how much space there is between the exhaust outlet and the muffler. If that space is too small, the exhaust can scrape or get damaged when you drive over bumps.

Term

resonator

A resonator is a muffler-like part in the exhaust that helps control noise. In the story, the exhaust got low enough to hit it, which then made the car sound dramatically louder.

Term

flange

A flange is a metal connection point where two exhaust pieces meet. If it’s positioned too low, it can scrape or get stuck when you drive over bumps or uneven roads.

Term

clamps

Exhaust clamps are the metal fasteners that hold exhaust pieces together. They help keep everything lined up while still allowing the exhaust to expand and contract.

Nissan R34
Car

Nissan R34

The Nissan R34 is a famous turbocharged Skyline GT-R from Japan. The host is saying that changing the exhaust (along with other tuning) should make the car feel and sound different than stock.

Term

body kit

A body kit is aftermarket body parts that change the car’s exterior styling. The host is saying it can also affect exhaust fitment because the rear bumper area may leave less space.

Term

oval muffler

An oval muffler is just a muffler with an oval shape. They’re considering it, but they’re worried it might not match or fit nicely with the new body kit.

S13
Car

S13

S13 is a Nissan chassis code that’s well known in the tuning world. The host is saying HKS has an exhaust option for the S13 that’s more like a regular muffler setup.

Term

test pipe

A test pipe is basically an exhaust part that replaces the catalytic converter. It can make the car louder and feel a bit freer, but it also means the car isn’t cleaning emissions the way it’s supposed to.

Topic

GTR festival

The speaker references seeing an exhaust in person at a GTR festival, using the event as context for why they wanted to try a particular setup. It’s a named enthusiast gathering tied to Nissan GT-R culture.

Term

cutouts

Exhaust cutouts are openings (often controlled by a valve) that let exhaust exit without passing through the rest of the muffler system. They’re used to dramatically change sound on demand, which is why the speaker says exhaust tech is “peaked” except for cutouts.

Term

titanium

Titanium is a strong, lightweight metal that can handle heat well, so some exhaust parts are made from it. It usually costs more than cheaper metals, which is why it comes up as a premium option.

Term

aluminum

Aluminum is a light metal that some people experiment with for exhaust parts. It can work in certain designs, but it’s not as common as other metals because exhaust heat is tough on materials.

Term

copper

Copper isn’t a common choice for exhaust systems. Exhaust parts have to handle a lot of heat and wear, so you usually see other metals instead.

Term

fart can

“Fart can” is slang for an aftermarket muffler that makes the exhaust very loud and raspy. People usually use it for the sound more than for smooth, quiet driving.

Term

single all the way back to a double

They’re talking about whether the exhaust system has one pipe/outlet or two. Two outlets usually means a “dual exhaust” setup instead of a single one.

Term

dual

“Dual” means there are two exhaust paths instead of one. The hosts are talking about how that can change the way exhaust gases move and how the system sounds.

Term

scavenging effect

“Scavenging” here means the exhaust pulses can help suck the next batch of exhaust gases out more efficiently. The idea is that the exhaust system can work like a tuned airflow network, not just a pipe that carries fumes away.
