Best Exhaust For 370Z: Compare Axle-Back, Cat-Back and Titanium Options

#1 · Best Overall

1. EOS Muffler Axle Back

• Material Type: Stainless Steel
• Weight: 20 lb
• Material: Stainless Steel

Best for: OEM-range dual-tip axle-back swap.

Why it ranks #1: Lists fitment for all Z34 370Z models, uses stainless steel, and includes paired gaskets plus nuts and bolts for its axle-back installation.

A direct-fit axle-back package for 2009–2021 Nissan Z34 370Z models gives owners a focused replacement without stepping up to a listed full cat-back system. Stainless-steel construction and 4.5-inch double-wall dual tips make the rear section the main change, while the included left-and-right gaskets and fasteners support the swap.

The stated all-model 2009–2021 fit range makes this a defined option for owners seeking an axle-back replacement across those model years. Its stainless-steel construction and 4.5-inch double-wall dual tips pair material choice with a prominent exhaust finish. The package includes a left-and-right exhaust pair, matching gaskets, and nuts and bolts, so the listed installation hardware is supplied together. Because this is an axle-back muffler system, it does not replace the entire exhaust path.

Skip it if you want a full cat-back system rather than an axle-back replacement; Auto Dynasty’s 4.5-inch cat-back is the listed broader-system option.

This suits 370Z owners seeking a stainless axle-back replacement with dual double-wall tips and included basic hardware. Its stated fitment spans 2009–2021 Z34 models, but buyers wanting a full cat-back should choose a broader system.

#2 · Full Cat-Back

2. Auto Dynasty Catback

• Weight: 80 lb

Best for: Cat-back system for power-focused builds.

Why it ranks #2: Provides a cat-back configuration for the 370Z with T-304 stainless steel, 2.25-inch inlet and 4.5-inch outlet connections.

A cat-back layout separates this Auto Dynasty system from axle-back replacements, giving 2009–2019 370Z owners a broader exhaust-section upgrade. The listing specifies 2.25-inch inlet and 4.5-inch outlet connections, along with larger pipes, low-restriction mufflers, and tuned resonators; together, those details frame its airflow-oriented, performance-focused use.

The 2009–2019 compatibility range gives buyers a defined model-year window, while the cat-back format extends beyond a rear axle-back section. Its 2.25-inch inlet and 4.5-inch outlet provide specific connection dimensions to consider when planning the installation. The description also names larger pipes, low-restriction mufflers, and tuned resonators as the airflow-focused hardware. The manufacturer claims a 15–25 horsepower or low-end-torque increase, but the listing does not establish that result for every vehicle or setup.

Skip it if you need a California-emissions-legal exhaust; the listing explicitly says this system is not CARB compliant.

This is for 2009–2019 370Z owners seeking a cat-back layout and specified inlet and outlet dimensions. Its non-CARB-compliant status is a decisive boundary for California emission models, so check that legal constraint before choosing it.

#3 · Lightweight Titanium

3. Tomei Titanium Muffler Kit

• Material Type: Titanium
• Weight: 12.6 lb
• Material: Titanium

Best for: Lightweight titanium early-model system.

Why it ranks #3: Its titanium system weighs 12.6 pounds and uses 80mm piping, but specified fitment is limited and later applications require a Tomei mid Y pipe.

At a listed 12.6 pounds, this full-titanium Type R kit is aimed at owners prioritizing a lighter exhaust for a 2009–2011 370Z VQ37VHR. Its stated 80mm piping, compared with 65mm OEM, and high-flow 152mm silencer connect the weight-focused package to an airflow-oriented layout.

The stated 12.6-pound system weight is 41.4 pounds lighter than the OEM system according to the listing, making weight reduction a central reason to consider it. Its 80mm piping versus 65mm OEM and 152mm high-flow silencer are specified performance-oriented dimensions. The kit includes pipes, silencer assembly, gaskets, clamps, springs, nuts, bolts, and a sound reducer ver.2, which consolidates listed components. Fit is limited to 2009–2011 VQ37VHR models; 2012+ cars require the Tomei titanium mid Y pipe.

Skip it if you own a 2012-or-newer 370Z and do not want to add the required Tomei titanium mid Y pipe.

This suits owners of 2009–2011 VQ37VHR 370Zs seeking a lightweight titanium full system with specified larger piping. The fit boundary matters: 2012-and-newer cars require the Tomei titanium mid Y pipe.

Listed on Amazon as: TOMEI Full Titanium Muffler Kit Compatible with 2009-11 NISSAN 370Z VQ37VHR, Type R Exhaust Single Exit. For 2012+ 370Z the Tomei Titanium mid Y pipe is required.

The product is listed for all Nissan 370Z models from 2009–2021, giving buyers a stated fit range.

• Material Type: Stainless Steel
• Weight: 4 lb
• Material: Stainless Steel

Best for: Lightweight muffler-delete axle-back.

#10

10. EOS Resonated Mid-Pipe

• Material Type: Stainless Steel
• Weight: 20 lb
• Material: Stainless Steel

Best for: EOS-compatible resonated mid-pipe.

Why it ranks #10: This is a separate resonated mid-pipe, not a complete exhaust; its listed compatibility is with EOS axle-backs and may exclude other aftermarket systems.

A three-piece, 2.5-inch resonated mid-pipe gives this Extreme Online Store part a specific role between exhaust sections on 2009–2021 Nissan 370Z Z34 models. Its listing names EOS axle-back compatibility, hand-crafted TIG welding, and mandrel-bent piping, making system matching central to the choice.

The stated fit range covers 2009–2021 Z34 370Z models, but the listing specifically says compatibility is with EOS Nissan 370Z axle-back exhaust and that it may not work with other aftermarket systems. That makes existing exhaust brand a key planning check. The 2.5-inch mandrel-bent piping and hand-crafted TIG welding describe the pipe construction, while the three-piece kit includes three pairs of gaskets and hardware. Bolt-on installation is listed, supporting a hardware-based connection workflow.

Skip it if you have a non-EOS aftermarket axle-back; the listing warns this mid-pipe may not work with other aftermarket exhaust systems.
