Got this exhaust for my 3.0T Q50 and I must say, it does NOT disappoint. Sure, it may not sound as glorious as a N/A VQ37, but man, give it an hour or so to bake in and this bad boy rips. Love the slick low growl it makes. Build is hefty and welds are superb. Quality is top notch! If anything else, getting lower and or full down pipes would release all of this beast's potential. Truly an experience!
