Product Specifications

2009–2020 Nissan 370Z 3.7L V6 (Z34) Single-Tip Cat-Back Exhaust

This single-exit cat-back exhaust is built for the 2009–2020 Nissan 370Z with the 3.7L VQ37VHR V6 in 2-door Coupe and Convertible (Z34) body styles. It replaces the exhaust section behind the factory catalytic converters with 3-inch stainless steel piping, a muffler, and a single outlet. Two stainless grades are available for the main pipes — 304 stainless steel or budget-friendly 201 stainless steel — so you can match the system to your budget without changing the rest of the design.

As a cat-back system, it is designed to keep the factory catalytic converters and O2 sensors in place. If your 370Z already runs aftermarket headers, test pipes, or a modified Y-pipe, confirm the inlet connection with our support team before ordering.

Specifications

The specifications below apply to both material options. The Material option selects the grade of the 3-inch main (bend) pipes: 304 stainless steel (SKU FLEXS22-00084SR-001-L) or 201 stainless steel (SKU FLEXS22-00084SR-000-L).

Component Material Thickness (mm) Notes
Bend pipes 304 stainless steel (SS304 option) or 201 stainless steel (SS201 option) 1.23–1.25 Set by the Material option
Muffler inner perforated tube 409 stainless steel 0.95–0.97 Inside the muffler body
Perforated tube end cap 304 stainless steel 0.87 Caps the inner tube
Flanges Stainless steel — Laser-cut for precise fit

Key Features

  • Single-Exit Cat-Back Layout: This is a full cat-back system rather than an axle-back, and it ends in one outlet instead of two. It covers the stainless main pipes, the muffler, and the single tip behind the factory catalytic converters, so the converters and factory O2 sensors stay in place.
  • Two Stainless Steel Pipe Grades: The Material option sets the grade of the 3-inch main pipes. SS304 (SKU FLEXS22-00084SR-001-L) offers higher corrosion resistance, while SS201 (SKU FLEXS22-00084SR-000-L) is the budget-conscious choice; the rest of the system layout is shared by both options.
  • Removable Muffler Insert: The muffler includes a removable dual-layer insert. Keep it installed for the tamer setting or remove it for a louder, more open tone, and switch back at any time without replacing the exhaust.
  • TIG-Welded Sections with Laser-Cut Flanges: The stainless piping is joined with TIG welds, and the system uses laser-cut flanges at its connection points, as described in the specifications above.
  • Multi-Grade Stainless Build: Both material options share the same muffler construction — a 409 stainless steel inner perforated tube and a 304 stainless steel end cap — with the 304/201 choice limited to the main pipes.

Common Pairing Parts

These parts are sold separately and are listed on this page as recommended pairing upgrades for the 370Z. Confirm each part’s fitment with your vehicle before ordering.

Check Before Ordering

  • This is a single-outlet cat-back exhaust for the 2009–2020 Nissan 370Z 3.7L V6 (VQ37VHR), 2-door Coupe or Convertible (Z34). Confirm your model year, engine, and body style before ordering.
  • The Material option sets your bend-pipe grade and SKU (SS304 = FLEXS22-00084SR-001-L; SS201 = FLEXS22-00084SR-000-L). Verify the option you select at checkout.
  • The factory catalytic converters and O2 sensors are retained with this cat-back; this system is not a test-pipe or catalytic-converter-delete setup.
  • If your 370Z already has aftermarket headers, test pipes, or a modified Y-pipe, the inlet connection can differ from a factory setup — contact our support team to confirm compatibility before ordering.
  • Individual hardware (gaskets, clamps, bolts) is not itemized on this listing. If you need hardware with the kit, confirm what is included before ordering.
