]]>Race / Competition / International Use Only
This product is designed for installation on a race-only vehicle, defined as a vehicle that is used exclusively for competition and that cannot be licensed or registered for use on the public roads and highways within the United States. This product is not available for sale on emissions-controlled vehicles within the United States without a completed AMS Race Waiver form. International users outside of the United States should act in accordance with their local laws and regulations.
AMS Performance VR30DDTT Street Full Downpipes are the best performing and most durable full 3″ mandrel bent units on the market. During testing our shop Q60 with our VR30 Full Downpipes, and Red Alpha Tune, our Engine Calibrators saw 20 horsepower gains over our VR30 Race Lower Downpipes! The power came on earlier and the twin turbo’s spool-up was significantly improved. The long gradual transitions within the mandrel bent pipe section allows exhaust gasses to maintain velocity without a buildup of back pressure inside of the system. We were able to design a superior product because of our superior engineering.
First in Class Durability and Performance From Proper Engineering
AMS is first and foremost an engineering company. The AMS Engineering team utilized Solidworks (3D software) to blueprint the inlet and outlets to optimize exhaust flow. The AMS Street Full Downpipes feature heavy gauge stainless steel to retain as much heat in the down pipe as possible. Our Engineers 3D printed the downpipes to ensure an OEM level of fitment. Our threaded O2 sensor bungs allow the use of factory O2 sensor. Our downpipes perform better and are not prone to cracking like the alternatives offered by some of the competition. AMS’ Engineering Team produced a product that doesn’t just perform better, they made it sound better too.
High Performance GESI Catalytic Converters
Utilizing EPA compliant catalytic converters from industry titan GESI, our AMS downpipes for the VR30DDTT are the perfect solution for increased performance and OEM-like fitment and emission control.
Our universal line of G-Sport Emissions Systems Catalytic Converters are designed to support the growing high performance aftermarket. To simplify your decision, our converter models target applications based on vehicle horsepower and exhaust sizing. Our High Output (HO) target up to 500 hp per exhaust bank, while our Ultra High Output (UHO) support up to 850 hp per exhaust bank.

The AMS Performance VR30DDTT Street Lower Downpipes are crafted for those who demand excellence in both performance and emissions compliance. Utilizing advanced engineering techniques, our SnailWorks© team employed 3D CAD software to design these downpipes with full 3″ mandrel-bent stainless steel tubing, ensuring superior exhaust flow and improved boost response and turbo spool up. The ultra high output GESI catalytic converters, compliant with EPA regulations and capable of supporting up to 850 HP each, provide a perfect blend of catalyst efficiency and removing exhaust back pressure within the system. Engineered for a flawless fit and long-lasting durability, these downpipes offer innovation and precision in every detail, making them an ideal upgrade for high performance enthusiasts.
First in Class Durability and Fitment From Proper Engineering
AMS is first and foremost an engineering company. The VR30DDTT Street Lower Downpipes were designed using Solidworks© 3D CAD software by our SnailWorks© Engineering Team to be the best performing on the market. Our engineers utilized 3D scans and computer aided design to blueprint the inlet, outlet, and mounting locations to optimize exhaust flow via mandrel bent full 3″ tubing. Utilizing 3D printed prototypes, our team was able to install and test fit and then rapidly refine our geometry in CAD resulting in perfect OEM-like fitment. Even the small details have been considered, including our robust integrated mounting brackets that allow the exhaust to be secured to the chassis. These brackets reduce flex, and means your pipes are not prone to cracking like the cheap alternatives offered by some of the competition. Our engineering mindset and attention to detail in the design of the new VR30DDTT Street Lower Downpipes is what sets it apart from everything else on the market.
Ultra High Output GESI Catalytic Converters
The GESI G-Sport catalytic converters integrated into the AMS Performance VR30DDTT Street Lower Downpipes offer exceptional performance and reliability. These 304 series stainless steel constructed converters are EPA compliant — ensuring they meet stringent emissions standards while delivering superior exhaust flow. Featuring a 300 CPSI cell count and a G-Sport triangle cell design, they effectively reduce back pressure, maximizing performance. The Double-Lock technology securely locks the substrate in place, and the proprietary precious metal wash coat guarantees consistent emissions reduction. Designed to withstand temperatures up to 1500°F, these catalytic converters are ideal for forced induction applications, providing the perfect balance of durability and efficiency within the exhaust system.
Our latest updates to our line of Advanced Series G-Sport Catalytic Converters expands our proven core technology to better support the growing high performance aftermarket. Our converter models target applications based on model year, vehicle horsepower and exhaust sizing. Our new Advanced Series is reinforced with our proven S-Wound Core and supports up to 850hp per converter.
