I really like it, but haven’t really had a chance to compare to other sounds except online. It’s definitely louder than stock, but not overly so. It has a deep mellow rumble at idle and cruising, but really comes alive when you open it up. I really like the pops and barking when decelerating.
The big debate was ATAK vs S type. From what I heard, the ATAK is louder and raspier. I didn’t want too loud so I went S type.
My big debate originally was Borla vs Corsa. I had the Corsa on my WK1 and loved the sound. Reminded my of a European exotic, like a Maserati sound. I didn’t go Corsa on my WK2 because of the design/aesthetics. The system for the WK2 is way too busy out back. They have four cans hanging under the rear bumper.
I’d also go cat back. The axle back was designed for 2014 and older WK2s that had a flutter valve in the mid mufflers.
