Are the AMS Performance Infiniti Q50 Q60 downpipes EPA compliant?

Yes. The AMS Performance Infiniti Q50 Q60 downpipes use ultra-high-output GESI G-Sport catalytic converters that are EPA compliant, so they retain catalysts rather than delete them. The 304 stainless cats support up to 850hp each while meeting emissions standards.

How much power do the AMS Performance Infiniti Q50 Q60 downpipes support?

The GESI catalytic converters in the AMS Performance Infiniti Q50 Q60 downpipes are rated to support up to 850hp each. Combined with full 3 inch mandrel-bent stainless tubing, they reduce back pressure for enhanced boost response and improved turbo spool-up.

Do the AMS Performance Infiniti Q50 Q60 downpipes fit the Nissan Z?

Yes. The AMS Performance Infiniti Q50 Q60 downpipes fit the V37 Infiniti Q50 (2014-2024), V37 Q60 (2017-2022), and RZ34 Nissan Z (2023-present), all sharing the VR30DDTT 3.0L twin-turbo V6 engine.

Will the AMS Performance Infiniti Q50 Q60 downpipes work with my existing exhaust?

Yes. The AMS Performance Infiniti Q50 Q60 downpipes include a 2.5 inch to 3.0 inch adapter for compatibility with stock, 2.5 inch, or 3 inch catback exhausts. The retained EPA-compliant cats also keep a subdued exhaust note that tames loud catbacks.

Do the AMS Performance Infiniti Q50 Q60 downpipes fit well and resist cracking?

Yes. The AMS Performance Infiniti Q50 Q60 downpipes were designed with 3D scans and CAD for OEM-like fitment, with robust integrated mounting brackets that secure the exhaust to the chassis, reducing flex and minimising the cracking common to inferior alternatives.

Description

AMS Performance Street Lower Downpipes for V37 Infiniti Q50 & Q60 / RZ34 Nissan Z

Infiniti Q50 Q60 downpipes from AMS Performance are the VR30DDTT Street Lower Downpipes, meticulously engineered for those who demand top-tier performance and emissions compliance. Designed by the AMS SnailWorks team in 3D CAD software, these Infiniti Q50 Q60 downpipes use full 3″ mandrel-bent stainless steel tubing for optimal exhaust flow, enhanced boost response, and improved turbo spool-up. They include ultra-high-output GESI catalytic converters, compliant with EPA regulations and capable of supporting up to 850hp each, striking the perfect balance between catalyst efficiency and reduced exhaust back pressure. Crafted for a flawless fit and long-lasting durability, and backed by over 23 years of AMS research and development in forced induction, they also fit the V37 Q60 and RZ34 Nissan Z sharing the VR30DDTT engine.

Why the AMS Performance Infiniti Q50 Q60 Downpipes?

AMS is fundamentally an engineering-driven company, and the Infiniti Q50 Q60 downpipes were designed by the SnailWorks Engineering Team in SolidWorks 3D CAD to be the best-performing downpipes available. The team used 3D scans and computer-aided design to precisely map the inlet, outlet, and mounting locations, optimizing exhaust flow with full 3″ mandrel-bent tubing, then used 3D-printed prototypes to install, test-fit, and refine the geometry for perfect OEM-like fitment. Robust integrated mounting brackets secure the exhaust to the chassis, reducing flex and minimizing the risk of cracking, a common issue with inferior alternatives.

Ultra-High-Output GESI Catalytic Converters

The GESI G-Sport catalytic converters integrated into the AMS Infiniti Q50 Q60 downpipes deliver outstanding performance and reliability. Constructed from 304-series stainless steel, they are EPA-compliant, meeting stringent emissions standards while providing superior exhaust flow. A 300 CPSI cell count and G-Sport triangle cell design effectively reduce back pressure to maximize performance, while Double-Lock technology securely holds the substrate in place and a proprietary precious-metal wash coat ensures consistent emissions reduction. Rated to withstand temperatures up to 1500°F, these converters are ideal for forced induction, offering the perfect balance of durability and efficiency. Retaining EPA-compliant catalysts also keeps a clean, subdued exhaust note that tames loud catback systems.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
