More Details on Our Top Picks
Invidia Gemini Cat-Back Exhaust System with Stainless Steel Rolled Tip for Nissan 370Z
The Invidia Gemini stands out for its combination of high-quality stainless steel construction and precise engineering, making it a top choice for those seeking a well-rounded upgrade. Compared to the Borla 140052, it offers a more refined sound and better fit, but at a higher price and with potentially louder volume. Its premium materials translate into durability and a noticeable performance boost, especially in sound and throttle response. The main tradeoff is that installation may require professional help, and the exhaust can be louder than stock, which might not suit all drivers. Overall, this system is ideal for enthusiasts who want a high-end, durable upgrade that balances sound with performance enhancement.
Pros:- High-quality stainless steel ensures durability and corrosion resistance
- Enhanced exhaust sound and performance
- Precise fit for Nissan 370Z models

The Auto Dynasty 4.5″ Rolled Catback offers a compelling mix of affordability and performance, making it an excellent choice for budget-conscious enthusiasts. While it doesn’t boast the same high-end finish as the Invidia Gemini, it provides a significant horsepower and torque boost, thanks to its durable T-304 stainless steel construction. Compared to the Borla 140052, it may produce a slightly louder exhaust note, but it maintains a straightforward bolt-on process that requires no modifications. This pick makes the most sense for drivers who want a noticeable performance upgrade without the premium price, though some may find the sound too aggressive or loud. It’s ideal for those looking for value rather than absolute refinement.

Auto Dynasty 4.5-inch Clamp-On Catback Exhaust Tip System for 2009-2019 Nissan 370Z
The Auto Dynasty Clamp-On System is designed with durability and performance in mind, especially appealing to owners of 3.7L V6 models who want a substantial upgrade. Its heavier weight of 60 lbs is a double-edged sword—indicating a solid build but also complicating installation. Compared to the Invidia Gemini, it offers a straightforward bolt-on process, but may lack the refined finish and sound quality, instead favoring durability and increased horsepower. Its specific focus on 3.7L engines limits its versatility, making it less ideal for other configurations. This system makes the most sense for owners who prioritize ruggedness and performance enhancement over subtlety or ease of installation.
Pros:- Increases horsepower and torque
- Made of durable, corrosion-resistant stainless steel
- Straightforward bolt-on installation with included hardware
Cons:- Heavy weight at 60 lbs complicates installation
- Designed specifically for 3.7L engines, limiting compatibility
Best for: Owners of 3.7L V6 Nissan 370Z models seeking a rugged, high-performance upgrade
Not ideal for: Casual drivers or those with lighter budgets who prefer easier, lighter systems

Compared to the Invidia Gemini, it offers a more aggressive sound signature and a longer-lasting, durable build. While installation can be somewhat technical, it rewards owners with a distinctive exhaust tone and improved power output. Its higher price reflects the premium materials and engineering, but it remains a favorite among serious enthusiasts who demand longevity and a proven performance boost.

The DNA MOTORING CBE-370Z-D-T3 excels at delivering increased horsepower and torque, especially for 3.7L VQ37VHR V6 engines, thanks to its mandrel bends and TIG-welded CNC flanges. Compared with the Auto Dynasty 4.5″, it offers a more engineered approach with tuned resonators and low-restriction mufflers, resulting in a deeper, more aggressive sound. Its stainless steel build promises durability, but installation requires some technical skill, and it’s not a universal fit.

Compared with the Invidia titanium system, it provides a more corrosion-resistant build, making it better suited for owners who prioritize longevity and a polished look.
