Key Features

  • Cat-Back Configuration: This system replaces the rear exhaust section for the listed Civic 1.5T Sedan application without representing a header, downpipe, or catalytic-converter replacement.
  • T-304 Stainless Steel: The mirror-polished stainless construction provides the verified material and finish information needed when comparing exhaust options.
  • Mandrel-Bent Tubing: The page specifies mandrel-bent tubing, helping buyers identify the system’s formed pipe construction.
  • N1-Style Muffler and Tip: The N1-style muffler is paired with a 3.8-inch outlet tip for the product’s stated rear-exit appearance and sound character.
  • Direct Bolt-On Layout: On the verified 1.5T 4-door Sedan application, installation does not require cutting, welding, or custom fabrication.
  • Included Hardware: The product page states that required installation hardware is included, so inspect all parts before removing the factory exhaust.

Sound Reference

The product page describes an N1-style tone. Actual sound in the cabin can vary with engine speed, transmission, load, and other exhaust modifications; use the customer-car video as a reference rather than expecting identical results on every vehicle.
