First ever full titanium exhaust for Audi S4/S5


We have finally released an Audi B9 system that will clear the sport differential without having any fitment issues. Our new B9 system has a new style mid pipe, the mid pipe goes down into one single larger diameter piping that routes past the sport differential without compromising any power loss.


The best sounding, most affordable B9 system has finally arrived. Give your 3.0L Turbocharged V6 the best sounding and most durable system out there. The B9 S4/S5 stock system limits your car to its potential in power and sound. This system does not only sound amazing, but it also has performance benefits. Our system allows you to gain 10-15 HP (when tuned) and give you an amazing sound with the valves open and stock sounding when the valves are closed.

“Amazed”- @s4.killacam

The product itself is amazing! Very nice finish and quality! Fitment came out wonderfully. Most importantly though in my opinion is the service. Valved was quick to respond to any of the questions I had even if they seemed a bit “dumb”! It created a great experience and something I wish more companies would do! No regrets buying this product!

As for the titanium catback
-Quiet and comfortable when needed with a quick flip of a button
-Loud and mean when needed to be with another click
- Honestly a bit more sound too than stainless but the tone is really where it’s at!
-Plus it’s titanium the weight savings is wonderful!
