Probably one of the best sounding exhausts out there for the B8/B8.5 S4/S5 platform with little to no drone. When the valves are open the car screams and it’s such a thrill. On the other hand when the valves are closed it’s basically stock-like (comes in handy). 100% do I recommend valved exhausts, exhaust system. On another note, the customer service is amazing, quick to respond and help you with whatever questions and what not you have.
My customer service experience was amazing start to finish. I was in the loop on the progress as well as the tracking information. I was able to get in contact very easily with questions or concerns. The product itself is amazing. This catback gave me the exact sound I was looking for when the valves are open but also gave me comfort when the valves are closed. I can’t recommend this product enough
