Best 370Z Exhaust System: Compare 10 Fitment Options

#1 · Best Overall

1. Auto Dynasty Cat-Back

• Weight: 80 lb

Best for: Full Cat-Back Upgrade.

Why it ranks #1: Its cat-back layout serves buyers seeking more than an axle-back, with listed 2009–2019 fitment and 2.25-inch inlet and 4.5-inch outlet connections.

A 4.5-inch outlet and cat-back layout set this Auto Dynasty system apart, enabling a broader exhaust-path upgrade than an axle-back change. It is listed for 2009–2019 Nissan 370Z models and pairs T-304 stainless steel construction with racing-style exhaust design.

The 2.25-inch inlet and 4.5-inch outlet identify the system’s connection dimensions, useful when planning an exhaust replacement. Its cat-back configuration reaches beyond the axle-back options in this roundup, while the supplied description attributes increased exhaust airflow to larger pipes, low-restriction mufflers, and tuned resonators. At 80 pounds, it is a substantial assembly to handle during installation. The listing states it is not legal for California emission models, a decisive regional restriction.

Skip it if you need a California-emissions-legal system; this listing explicitly excludes California emission models.

Choose this cat-back if you want a larger exhaust-path replacement for a 2009–2019 370Z and can accommodate its 80-pound assembly. California emission-model owners should rule it out because the listing says it is not legal there.

#2 · Lightest Full-System Option

2. Tomei Full Titanium Kit

• Material Type: Titanium
• Compatible with Vehicle Type: 2009-2011 370Z VQ37VHR
• Weight: 12.6 lb

Best for: Lightweight Titanium Setup.

Why it ranks #2: The complete titanium kit weighs 12.6 pounds and lists 80mm piping, but fitment is specified for 2009–2011 cars; later models need a Tomei mid Y pipe.

At 12.6 pounds, the Tomei full-titanium kit weighs 41.4 pounds less than the stated OEM system, enabling a substantial exhaust-weight reduction. Its Type R single-exit layout is specified for 2009–2011 370Z VQ37VHR models, with a mid Y-pipe requirement for 2012-and-newer cars.

The 80mm piping is larger than the listed 65mm OEM piping, while the 152mm high-flow silencer supports the product’s exhaust-flow focus. Titanium construction keeps the complete system’s stated weight to 12.6 pounds, a practical advantage when handling the assembly. The kit includes pipes, silencer, gaskets, clamps, springs, nuts, bolts, and a sound reducer. For 2012+ 370Zs, the listing specifically requires Tomei’s titanium mid Y pipe.

Skip it if you have a 2012+ 370Z and want a kit without a separate mid Y-pipe; this listing requires Tomei’s titanium mid Y pipe.

Pick this kit for a lightweight titanium single-exit setup on a 2009–2011 VQ37VHR 370Z. The year boundary matters: 2012-and-newer cars require the specified Tomei titanium mid Y-pipe in addition to this kit.

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.

A resonated axle-back layout pairs with a burn-finish stainless exterior on this TUNERBITS system, enabling buyers to choose the resonated version rather than its straight counterpart. It is listed for 2009–2021 Nissan 370Z models, with 2.50-inch-ID piping and double-wall 4.50-inch tips.

The resonated axle-back format keeps the replacement at the rear while distinguishing it from the listed straight axle-back products. Stainless steel construction carries the burn finish, and the double-wall tips measure 4.50 inches outside diameter for the specified outlet treatment. The 2.50-inch inside-diameter piping and 3/8-inch flanges provide useful dimensions when planning the connection. Installation instructions are not supplied; the listing recommends a shop or factory manual.

Why it ranks #4: It pairs a gloss-black stainless finish with a resonated axle-back layout, 2.50-inch piping, and 4.50-inch outside-diameter tips for listed 2009–2021 cars.

The gloss-black finish paired with a resonated axle-back configuration defines this TUNERBITS option, enabling a dark-finish rear-section replacement. The listing covers Nissan 370Z models from 2009–2021 and specifies stainless steel construction, 2.50-inch-ID piping, and double-wall 4.50-inch tips.

Choosing the resonated layout separates this product from the brand’s listed straight axle-back versions, while keeping the system’s scope at the axle-back. Stainless steel provides the stated base material for the gloss-black finish. The 4.50-inch outside-diameter double-wall tips and 2.50-inch inside-diameter piping identify the key outlet and pipe dimensions; 3/8-inch flanges are also specified. Since no installation instructions are included, use the referenced shop or factory manual for installation guidance.

The axle-back configuration limits the replacement to the rear section, while the resonated design identifies its layout relative to straight options.

8. TUNERBITS Gloss Black Straight Axle-Back

• Material Type: Stainless Steel

Best for: Gloss-Black Straight Axle-Back.

Why it ranks #8: Its gloss-black stainless construction and 2.50-inch piping suit buyers prioritizing finish, though this is a straight axle-back rather than a complete system.

Gloss-black stainless steel gives this TUNERBITS straight axle-back its defining finish, enabling a dark appearance at the rear while retaining the listed straight configuration. The product is specified for Nissan 370Z models from 2009–2021, with 2.50-inch-ID piping and double-wall 4.50-inch tips.

Mandrel-bent piping and hand-crafted TIG welding describe how the stainless steel mid-pipe is formed, while the 2.5-inch diameter identifies its pipe size.
