370Z exhaust upgrades shape more than sound. They change how the car feels pulling away from a stop, merging onto a freeway, or settling into a long highway cruise. The right setup depends on whether the priority is simpler bolt-on replacement, lighter rear hardware, or a fuller cat-back layout with a stronger finish.
The seven picks below focus on fitment, pipe layout, tip style, and install scope. That makes the shortlist useful for daily-driven Z cars, weekend garage projects, and drivers who want a cleaner rear view without guessing at part compatibility.

More Details On Our Top Picks
Axle-back swaps like this one tend to suit owners who want a cleaner rear section without moving deeper into the exhaust system. The stainless construction and double-wall dual tips give it a finished look, while the included gaskets and hardware help keep the install list straightforward.
That makes it a sensible fit for a daily-driven 370Z that still needs civil street manners. Compared with the louder muffler-delete style below, this EXT-MD005 setup should appeal to drivers who want a more measured step rather than a full personality change.
Strong Points
- Axle-back layout keeps the upgrade focused at the rear of the car.
- Stainless steel construction suits regular road use and resists the tired look that cheaper finishes can pick up.
- 4.5-inch double-wall dual tips create a more finished rear appearance.
- Included gaskets and nut-and-bolt hardware reduce parts chasing during installation.
Things To Consider
- Axle-back changes are narrower in scope than a full cat-back system.
- The stainless silver finish is more subtle than the burn or titanium-style tips used on some of the other picks.
- Owners who want a deeper hardware change may lean toward the DC Sports Y pipe or the Invidia cat-backs.
Feature Card
Who It Suits Best
Street-driven 370Z setups that want a rear-only refresh without jumping into a louder, full-length exhaust change.
Where Another Pick Suits Better
Invidia HS09N7ZGID Gemini Cat-Back Exhaust System with Titanium Rolled Tip fits drivers who want a more complete exhaust change with a stronger visual accent.
A cat-back system replaces a larger section of the exhaust than an axle-back, so this Invidia option sits in a more committed upgrade lane. The 60 mm piping and 110 mm titanium rolled tip give it a performance-minded profile with a cleaner visual edge at the rear.
That broader scope makes sense for Z owners who want a more complete change in tone and flow than the first pick offers. The trade-off is simple, more hardware means more install effort, so this suits garage projects or shop installs better than quick cosmetic swaps.
Highlights
- Cat-back design reaches farther into the exhaust path than an axle-back setup.
- 60 mm piping gives it a clear performance-oriented layout.
- 110 mm titanium rolled tip adds a distinct finish at the rear.
- Fits 370Z applications from 2009-up, which keeps the compatibility window broad.
- Well matched to drivers who want a more noticeable step than a rear section swap.
Room For Improvement
- The larger scope usually takes more time to install than the axle-back picks.
- Titanium styling is more assertive than the stainless look on the sister Invidia model below.
- Stock-quiet expectations are unrealistic in this category, so the tone change deserves consideration before purchase.
Technical Sheet
Who Will Love This
370Z owners seeking a more comprehensive exhaust change with a stronger visual finish and a performance-oriented pipe layout.
Skip It When
Auto Dynasty 4.5″ Rolled Catback Exhaust System for 2009-2019 370Z makes more sense for shoppers who want a simpler rolled-tip look and a more straightforward cat-back route.
This version pushes farther toward a louder, more direct rear-section change than the standard muffler axle-back above. It still uses stainless steel and the same double-wall dual-tip format, so the visual theme stays polished even as the exhaust path becomes simpler.
That mix suits owners who want the rear of the car to feel more aggressive without moving into a full cat-back package. The honest read is that a muffler-delete style is more specialized, so it fits best where sound and attitude matter more than restraint.
Bright Spots
- Muffler-delete layout creates a more direct rear exhaust path.
- Stainless steel build helps it fit the rhythm of regular street use.
- Double-wall dual tips preserve a finished appearance even with the simpler layout.
- Included gaskets and hardware support a cleaner installation process.
Points To Note
- The more aggressive layout is less restrained than the standard axle-back version.
- Drivers who want a balanced street tone may prefer the non-delete EXT-MD005 instead.
- Careful sealing during install matters, since rear-section swaps depend on solid fitment at the joints.
Core Details
Whose Shelf It Belongs On
370Z owners chasing a sharper rear-exhaust character and a simpler axle-back route than a full cat-back system.
Another Choice May Suit
Extreme Online Store 370Z Muffler Axle-Back EXT-MD005 works better for drivers who want the same general fitment with a less aggressive sound direction.
The Y-pipe sits earlier in the exhaust path than the rear-only swaps, so it affects how the system moves gases before they reach the back of the car. DC Sports also lists improved ground clearance and a deleted flex section, which matters on lowered cars or on driveways with awkward approach angles.
That broader fitment across 370Z, 350Z, G35, and G37 platforms makes it especially useful in mixed-project garages. Compared with the Invidia and Auto Dynasty cat-backs, this is the more targeted hardware change for someone who wants a single structural upgrade rather than a full system replacement.
Upsides
- Y-pipe placement can free up flow earlier in the exhaust route.
- Deleting the flex section simplifies the hardware layout.
- Ground-clearance improvement is useful on lowered builds.
- Quick bolt-on installation suits owners who want a focused project.
Softer Spots
- The part only addresses one section of the exhaust, so the change is narrower than a cat-back.
- Vehicle fit spans several platforms, which means careful application matching still matters.
Built With In Mind
Drivers with a 370Z, or a related Z/G chassis, who want an earlier-stage exhaust upgrade and better clearance without replacing the whole system.
Swap It Out When
Invidia HS09N7ZGID Gemini Cat-Back Exhaust System with Stainless Steel Rolled Tip suits shoppers who want a complete rearward system rather than a mid-pipe style change.
This cat-back mirrors the titanium-tip Invidia above in layout, but the stainless tip gives it a quieter visual tone. The 60 mm pipe diameter and 110 mm tip size keep the hardware story clear, and that consistency helps when the goal is a cleaner rear presentation rather than a flashy finish.
For street cars that see regular commuting, that restraint can make sense. The trade-off is mostly aesthetic, since the underlying fit and layout remain in the same performance-minded category as the titanium version.
Best Bits
- Cat-back format gives it a broader system footprint than axle-back options.
- Stainless steel rolled tip creates a more understated rear accent.
- 60 mm piping and 110 mm tip sizing mirror the performance-oriented structure of the titanium-tip sibling.
- Fits 2009-up 370Z applications, which keeps the model range useful.
Minor Gripes
- The stainless tip is less visually distinctive than the titanium version.
- Owners wanting only a rear-section swap may find a cat-back broader than necessary.
Feature Rundown
Best Suited To
370Z owners who want the same Gemini layout as the titanium-tip model, but with a more subdued stainless rear finish.
Look Elsewhere When
Burn Stainless Resonated Axle Back Muffler Exhaust for Nissan 370Z 2009-2021 suits shoppers who want a rear-only package with a burn-finish visual accent.
The burn finish gives this axle-back a more customized look than the plain stainless options above, and the resonated layout adds another layer of hardware detail. With 4.50-inch outer diameter tips, 2.50-inch inner diameter piping, and double-walled tips, it leans toward style-conscious street builds.
That makes sense for owners who want the rear of the car to look deliberate without stepping into a full system overhaul. One thing worth considering is finish care, since a burn-coated look tends to show road grime more readily than a plain polished surface.
Positives
- Burn finish gives the rear section a more distinctive look.
- Resonated axle-back design adds another tuning element to the setup.
- 4.50-inch outer tips create a strong visual presence.
- 2.50-inch inner piping keeps the hardware details specific and clear.
Points To Note
- The coated finish may ask for a little more cleaning attention than plain stainless surfaces.
- Rear-only scope keeps it narrower than the cat-back systems in this list.
- Style comes forward quickly here, so restraint-seeking setups may prefer the more subdued Invidia stainless model.
Who Should Grab It
370Z owners who want a rear-mounted exhaust piece with a stronger visual character and a resonated layout.
Where A Sibling Pick Shines
Extreme Online Store 370Z Muffler Axle-Back EXT-MD005 suits drivers who want a simpler stainless look with the same broad model-year fitment.
This Auto Dynasty cat-back lands in the middle ground between a simple axle-back and the more feature-heavy Invidia systems. The 4.5-inch rolled tip keeps the rear view clean, and the broader cat-back format suits owners who want a fuller exhaust change than a rear muffler swap.
For commuters who still want a weekend-project feel, that balance is useful. It does not carry the extra visual flair of titanium or burn-finish tips, but the trade-off is a more restrained look that can suit a lot of daily-driven cars.
Reasons To Buy
- Cat-back layout reaches farther into the system than rear-only options.
- 4.5-inch rolled tip gives the back end a tidy, straightforward finish.
- Works well for drivers who want a mainstream exhaust upgrade path.
- Less ornate styling can suit a cleaner factory-plus look.
Honest Caveats
- Fitment coverage stops at 2019, so later model years need a different route.
- The styling is simpler than the Invidia titanium or TUNERBITS burn-finish options.
Perfect Match For
370Z owners seeking a classic cat-back upgrade with a modest rolled-tip appearance and a broad street-use appeal.
A Better Fit Elsewhere
Invidia HS09N7ZGID Gemini Cat-Back Exhaust System with Titanium Rolled Tip suits drivers who want a more assertive rear accent and the same cat-back depth.
What To Weigh Before Choosing A 370Z Exhaust
Mistakes Worth Dodging
Fitment comes first. A 370Z axle-back, Y-pipe, and cat-back are not interchangeable in scope, so the installed layout needs to match the goal before any finish details matter.
Tip style can also distract from the larger question of how much system change is actually wanted.
The Upgrade Payoff
Higher-tier cat-backs usually cost more because they replace more of the system and use more material. Larger piping, larger tips, and broader coverage also add to the overall hardware load.
That extra spend makes more sense for drivers who want a deeper exhaust change rather than a rear-only visual refresh.
Key Points To Compare Across These Picks
Wrong Turns To Avoid
Many shoppers focus on tip size and overlook fitment year range, which is the first thing that should line up.
Where The Extra Money Goes
In this category, the higher price usually tracks with longer pipe runs, more complete system coverage, and more specific finish work.
Frequently Asked Questions
What Is The Main Difference Between Axle-Back And Cat-Back Exhausts?
An axle-back swap changes only the rear section behind the axle. A cat-back reaches farther forward and replaces more of the exhaust path.
Are Larger Tips Mostly About Appearance?
Yes, tip diameter mostly changes the rear visual presence. It can also signal a more performance-oriented layout, but the full system design matters more than tip size alone.
Does A Y-Pipe Make Sense For A 370Z Street Car?
It can, especially for drivers who want a focused hardware upgrade without replacing the whole exhaust. Clearance and flow changes make the most sense on modified or lowered cars.
Why Do Some Exhausts Use Double-Wall Tips?
Double-wall tips have a layered construction that gives the rear finish a more substantial look. That design detail also helps the tip area appear more complete from behind.
Which Option Fits A Mild Daily-Driven Setup Best?
The Extreme Online Store 370Z Muffler Axle-Back EXT-MD005 and Auto Dynasty 4.5″ Rolled Catback Exhaust System are the calmer choices here. Both lean toward a cleaner street look rather than the more aggressive layouts in the list.
