07 TL-S Few Issues P0420 Need Some Guidance/Help

Hello all, been a while since I've logged onto the forum, But I've had my TL-S (6MT) for about 2 years now, and for the most part has been a solid and reliable car considering the Mileage. Its now at 138,000 mi. and I'm needing to address a few issues. Could you all please point me in the right direction. Just to start, I've scoured the forums for these issues thouroughly and SEARCHED, So please don't flame me lol.

1. The first and main issue I've been trying to hunt down and address for the past 6 months to a year is this excessive road vibration while driving. It used to be much worse, and the car would veer and torque steer to the right very badly, but I've gotten an alignment a couple times, Brand new tires for the front, and rebalanced my tires, and finally, I replaced the Control Arm Compliance Bushings. The road vibration has improved slightly, but is definately noticeable at highway speeds of 70mph+, and can feel it in the steering wheel.

Could it possibly be my motor mounts causing the vibration? Ive noticed that my driver side mount has some slight tearing/cracking in the rubber, and the driver side I'm unsure of as it has a cap covering it.

2. The second and most recent issue I've encountered is a CEL code P0420, Catalytic Deficiancy Bank 1. Ive had a couple Bank 1&2 Lean codes (P3071 & P3072 I believe) come on once or twice in the winter the 2 years I've owned the car, but they always went away on their own and I just figured the O2 sensor was just being lazy or was a slight misreading. But this P0420 Code I'm a little concerned about. I cleared the code with a code scanner, and drove the car for about 3 days and Filled up with Shell Premium 93 Octane fuel, and Today the same code came back.

So, What are my chances that my Bank 1 Cat is actually bad, or is it possibly my O2 Sensor is finally going out? I don't want to blindly throw money at the car and spend more $$ fixing the issue.

BTW, if my cat truly is bad, I've been considering RV6 HFPC's, and was wondering if they would keep the CEL from coming on and allowing me to pass emissions with the O2 Sensors installed.

Thanks in advance for the support and advice guys :thumbsup::thumbsup:
