MagnaFlow Sys C/B 02- Audi A4 1.8T AWD

If you're looking to give your 2002-2008 Audi A4 Quattro with the 1.8L or 2.0L engine a more engaging driving experience, this Touring Series cat-back exhaust system from Magnaflow is a solid choice. It's designed to replace your stock exhaust from the catalytic converter back, aiming to improve both the sound and the performance of your car for everything from daily driving to longer trips.

This system is built from durable 409 stainless steel, which helps resist corrosion and stand up to the miles. The main piping is 2.5 inches in diameter and uses mandrel bends, meaning the pipe's diameter stays consistent throughout the bend. This allows exhaust gases to flow more freely than with crush bends, which can help increase horsepower and torque. The system features a dual split rear exit with 4-inch polished double-wall angle-cut tips, giving your A4 a sportier look. Inside, it uses a straight-through muffler design that Magnaflow says results in moderate exterior and mild interior sound levels, so you get a noticeable exhaust note without it being overwhelming.

Magnaflow used extensive 3D scans during development to create a direct-fit design, which should make installation straightforward. It's manufactured using CNC precision robotic techniques and comes with a limited lifetime construction warranty from Magnaflow. You'll want to refer to the manufacturer's installation instructions for specific details on mounting hardware and procedures.
