Downpipe Nissan 350Z Decat

Downpipe Nissan 350Z 60 mm – stainless steel, straight-through mufflers, flexible joints

The 60 mm performance downpipe for Nissan 350Z is one of the most effective exhaust upgrades for this legendary Japanese sports car. Built from durable stainless steel, and equipped with straight-through mufflers and flex joints, it combines increased horsepower, improved durability and a deep, aggressive exhaust tone. This upgrade is ideal both for daily driving enthusiasts and for track users who want to unleash the full potential of their Nissan 350Z.

Why upgrade the downpipe on a Nissan 350Z?

The factory exhaust system on the 350Z is a compromise between emissions standards, comfort and performance. In practice, the stock downpipe restricts exhaust flow, increases back pressure and limits the true sound of the VQ35 engine. Installing a 60 mm stainless steel high-flow downpipe removes those restrictions and delivers:

• Horsepower and torque gains of up to 10–20 HP depending on setup
• Improved throttle response and stronger mid-range acceleration
• Reduced back pressure and less engine stress under load
• Deeper, more aggressive exhaust sound typical of performance cars
• Durability against heat and corrosion thanks to stainless steel construction
• Direct bolt-on installation with no welding or cutting required

Stainless steel construction

Material choice is critical in performance exhaust components. This downpipe is made from T-304 stainless steel, resistant to rust, heat and cracks. It ensures years of reliable use even under hard driving conditions, making it the perfect solution for performance builds and track use.

Straight-through mufflers for a performance sound

The downpipe features integrated straight-through mufflers that maximize flow while enhancing the exhaust tone. The result is a deeper, race-inspired sound that transforms the character of the 350Z. Many owners highlight the improved exhaust note as one of the most satisfying aspects of this modification.

Flex joints – reliability and comfort

Flex joints are built into the design to reduce vibrations and prevent cracking of the exhaust system. This improves long-term durability and reduces unwanted resonance in the cabin. Whether you use your car daily or on the track, flex joints help extend the life of the exhaust system while maintaining comfort.

Compatibility – which models does it fit?

This downpipe is designed specifically for the Nissan 350Z and fits all engine versions (VQ35DE and VQ35HR), manufactured from 2003 to 2009. It is a direct replacement for the OEM downpipe and requires no additional modifications.

Technical specifications

• Pipe diameter: 60 mm
• Material: stainless steel T-304
• Features: straight-through mufflers, flex joints
• Installation: direct bolt-on (plug & play)
• Compatibility: Nissan 350Z (2003–2009, all versions)

Benefits of installing a 60 mm performance downpipe

Upgrading to this downpipe is one of the most effective ways to improve the driving experience in a Nissan 350Z. Key benefits include:

• Horsepower and torque gains for improved acceleration
• Sharper throttle response and stronger mid-range performance
• Sporty, aggressive exhaust tone with a deeper growl
• Durability – resistant to corrosion and extreme heat
• Lightweight design compared to stock components
• Direct bolt-on fitment without modification
• Suitable for both daily driving and racing applications

Catless downpipe – what you should know

This performance downpipe is often chosen in a catless (decat) configuration for maximum flow and power gains. While this delivers the most aggressive sound and best performance results, users who drive their cars daily may also consider using a high-flow catalytic converter. Either way, upgrading the downpipe transforms the 350Z into a sharper, more powerful machine.

Summary – the perfect exhaust upgrade for Nissan 350Z

If you own a Nissan 350Z and want to increase performance, improve throttle response, reduce back pressure and enjoy a deeper, sportier exhaust note, the 60 mm stainless steel downpipe with straight-through mufflers and flex joints is the perfect choice. It combines reliability, performance gains and a racing-inspired sound, making it one of the most recommended exhaust upgrades for the 350Z platform.
