# aFe Power 49-46403 MACHForce XP Cat-Back Stainless Steel-409 Exhaust System for 2009-2016 Audi A4 and More

### Performance Overview

This mandrel bent, stainless steel, MIG-welded, exhaust system is designed using a race inspired 3-step design (2.75"-2.50"-dual 2.25") increasing exhaust velocity which improves horsepower, torque and throttle response. The dual exit double walled 304 stainless steel tip gives your A4 a subtle yet aggressive stance. The single 2.5" inlet to dual 2.25" outlet straight through designed muffler eliminates high frequency resonance which allows for a quiet idle and an aggressive on throttle sound. This exhaust uses all factory hanger locations for a hassle free installation. No modifications necessary
