STM Audi RS3 Titanium Single Exit Turbo-Back Exhaust

The STM Titanium Single Exit Turbo-Back Exhaust represents the epitome of performance, quality, and functionality! Crafted entirely from titanium, this exhaust system, including the stainless steel downpipe, weighs a mere 24.5 pounds compared to the factory parts weighing 80.9 pounds - resulting in an impressive weight saving of over 56 pounds!

Every component is meticulously hand fabricated and TIG-welded in-house at STM. The full 3.5" stainless steel downpipe features a billet V-band flange designed to seamlessly mate with your factory turbo. From there, the downpipe connects to the 3.5" titanium exhaust, culminating in a sleek, lightweight, 4" single exit tip for a clean and aggressive look.

Vehicle Fitment: 
2017-2020 Audi RS3 
 
Oxygen Sensor Bungs: 
The downpipe has three o2 bungs. Two to accommodate your factory sensors and an extra bung that can be used with an aftermarket wideband or sealed off with the included plug if not used. 
 
Remflex Graphite Gasket: 
The 1/8" thick gasket is designed to crush 50% to perfectly fill gaps in the flange surface. 
 
Tip Options: 
The 4" tip is available brushed titanium or burned blue for a show quality finish! 
 
Turbo Clamp: 
You can re-use your existing, factory clamp.
