AMS Performance VR30DDTT Street Full Downpipes W/GESI Cats

The AMS Performance VR30DDTT Street Full Downpipes are the ultimate upgrade for your Infiniti Q50, Q60, or Nissan Z equipped with the 3.0L twin-turbo V6. Built for performance enthusiasts who demand both power and reliability, these precision-engineered 3” downpipes optimize exhaust flow to unlock gains of up to +20 horsepower over AMS Race Lower Downpipes, while delivering faster spool-up and smoother throttle response.

Constructed entirely from 304 stainless steel and TIG-welded for durability, each downpipe integrates EPA-compliant GESI high-flow catalytic converters rated for over 800 horsepower. The result is a perfect balance of performance, strength, and emissions control.

Designed with advanced SolidWorks 3D modeling, every bend and transition has been optimized to minimize back pressure and heat buildup. The included 2.5”–3.0” adapter ensures compatibility with both stock and aftermarket cat-back systems, providing true plug-and-play installation with OEM-like fitment and clearance.

When paired with the AMS Red Alpha Tune, these downpipes unleash the VR30’s full capability — enhancing power, response, and exhaust tone. Expect a deep, throaty sound under throttle with no excessive drone, thanks to precision-engineered flow paths and smooth turbine transitions.

Backed by AMS Performance’s unmatched reputation for engineering and quality, the VR30DDTT Street Full Downpipes are the premium choice for any enthusiast seeking maximum power without compromise.
