Replace cats?
Hey guys, I have a 2000 c5 m6 that is mostly stock except for a blackwing and a zo6 titanium exhaust. I really want to upgrade the exhaust for both power and sound but I don't think I want to do headers. The reason for that is the car only has 8k miles on it and I don't want to alter it too much. I have been thinking about replacing my 4 cat system with the random tech high flow cats or the off road pipe with the sims. My question is, would it be worth the money and effort? Would it sound good? Thanks for your input!

In my honest opinion, YES, it would provide you a small gain in HP and TQ. The best part is that you will soon tire of your small gain in HP/TQ and desire MORE HP and TQ!!!!! WITH THE SWITCH TO A HIGH FLOW cats,,, Your already set for more FUN!
Get rid of the precats and install the high flow cats!
