"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." —Chad M D from Lead, SD bought a Magnaflow Catalytic Converters - 49 State Legal for a 1990 Volvo 740.
