Key Features
- Left and right pipes: Replaces both factory downpipe sections as a pair, from the listed factory flange connection toward the cat-back connection.
- Catless layout: Removes the factory catalytic converter sections on both banks for an off-road or competition exhaust build.
- 2.4-inch mandrel-bent stainless tubing: The listed full-diameter bends avoid the factory crush-bent neck-down, stated on the current page as roughly 2.1 inches at its choke point.
- Pre-welded O2 sensor bungs: The listed mounting points let the factory downstream sensors thread into the replacement pipes without drilling or welding.
- TIG-welded construction and CNC-machined flanges: The listed joints and connection surfaces are intended for durable assembly and a bolt-on fit.
- Silver stainless finish: The listed solid stainless construction is intended to resist moisture, road salt and thermal cycling without a painted coating.
Performance and Exhaust Character
The current product information describes reduced backpressure, stronger midrange pull from 2,500 RPM to redline, improved top-end power and throttle response, and a more open exhaust note. It states that, when paired with a Stage 2 tune from APR, Integrated Engineering, 034Motorsport or JHM, the setup can produce 30–50 AWHP and 40–60 lb-ft over a Stage 1 flash. These figures depend on the vehicle and tune.
