Borla Cat Back system for 02-08 Audi A4 Quattro 2.0L 4cyl

This Borla S-Type cat-back exhaust system is built from premium T-304 stainless steel, which is stronger and more resistant to corrosion than T-400 series steel. The system features ultra-smooth mandrel bends that help maximize exhaust flow and power. Borla engineers use computer modeling and advanced sound analysis to tune each system, aiming to create a distinctive sound that also provides useful acoustic feedback to the driver for gear selection and throttle input.

The S-Type system is designed to unleash hidden horsepower by increasing exhaust velocity. This can lead to improved driving excitement and potentially better fuel economy. The polished T-304 stainless steel tips give the rear of your Audi A4 Quattro a clean, performance-oriented look. Borla's patented straight-through and multi-core technology is at the heart of this system, ensuring it performs as well as it sounds.

This cat-back system replaces the factory exhaust from the catalytic converter back. It's engineered for a precise fit on your 2002-2008 Audi A4 Quattro, whether it's a sedan or Avant, with either the 1.8T or 2.0T engine, and automatic or manual transmission. Borla backs this system with a Million-Mile Warranty, reflecting their long history and experience in exhaust manufacturing.
