It sounds great and seems to help with response. However, be aware that on an 2014 Jetta 1.8T, it will take a custom pipe extension. Not a big deal.

2 major differences from stock: 1. the o2 sensor is now located on the cat - pre-filteration - instead of the "Y" pipe. 2. the cat is shorter than the stock cat, but my new "Y" pipe was longer than stock so there was 0 net difference. The Volvo (Jerry) is more torquie and has a smoother power curve. Jerry is far more happy now.

Works well. No more cel. Only complaint I had was the bottom portion was not threaded for studs so I had to use bolts not a big deal but clearance was a little challenging getting bolts that fit just right.
