STM Tuned Inc.


Vehicle Fitment:
2017-2019 Audi RS3

The STM Titanium Single Exit Turbo-Back Exhaust is the pinnacle of performance, quality and function! The full Ti exhaust with stainless downpipe weighs only 24.5 pounds vs the factory parts weighing 80.9 pounds - saving you over 56 pounds!

All components are hand fabricated and tig-welded in-house at STM. The full 3.5" stainless steel downpipe features a billet v-band flange to mate perfectly to your factory turbo. The downpipe then bolts to the 3.5" titanium exhaust and continues on straight through with a clean, lightweight, 4" single exit tip.

Oxygen Sensor Bungs:
The downpipe has three o2 bungs. Two to accomodate 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. If you ned a new one, it is available here: 8V0253460.
