The Sound

Capitalizing on the design innovations and success of our 996 and 997 range, the starting point for designing the 991turbo exhaust had been set high. Our trademark perfect x pipe geometry, harmonically tuned silencer geometry, Inconel 625, and our proprietary acoustic silencer packing materials result in a system that has become famous for that perfect sound. Zero drone, and a raised pitch raucous incendiary howl in higher rpms and hard throttle. The design is so perfect, that you can even run catless versions silently at cruising speeds, only unleashing that howl when you drive the car hard.

During development there were some clear evolutionary design steps that we could incorporate. The secondary tail pipe allowed us to integrate an effective gas overflow system. The concept was conceived at the fluid dynamic modelling stage, and effectively works to cut low rpm noise, while allowing an effective increased cross section at higher rpms producing a more accentuated Jekyll and Hyde personality, and slightly broader torque curves.

Gentle Retinal — No Irritation for Me
Color: Pink (PDRN)
I was honestly nervous to try these because they contain retinal, and the under-eye area can be sensitive. But I had zero irritation. No burning, no redness, no peeling. They feel cooling and soothing when applied, and the hydrogel texture stays in place without sliding around. After consistent use, my under-eye area looks smoother and more refreshed. I’ve noticed subtle improvement in fine lines and overall brightness. If you’re curious about trying retinal in a gentle way, this is a great entry point. Just make sure to use sunscreen during the day, as you would with any vitamin A product.

Hydrates well
Color: Pink (PDRN)
So far the product has been nice. My understanding is that eye area looks hydrated. It does not diminish the under eye bags. Have been using for a few weeks. Maybe I’ll give it more time to see better results.

Such a pampering treat!
Color: Pink (PDRN)
Ok I love these!!! I’ve started using them almost every morning! They just feel like a little pamper before I start my day. They definitely tighten up my under eye and decrease puffiness. I try to leave them on for 25 min or so. Maybe not quite as good as the Peter Roth but I feel like I can use them frequently due to the reasonable price point and still see some results. I save the Peter Roth for a couple times a month. Definitely repurchasing these.

Eye patches that work
Color: Pink (PDRN)
Love them! Cooling to the eyes, easy to apply with no slipping. These eyes patches work and they’re great for the price. The only patches I’ll buy going forward. I just apply my eye cream first and then follow with the patches and you can definitely see the results once removing.
