What is the diamater going in and out of the cat? I also tried to take off the cat (just to look) and broke one of the bolts. What's the old addage, Righty Tighty, Lefty Loosey, RIGHT. Is this one of the few times that left turns do not equate to lossening a bolt? Oh yeah, I have also heard about an "exhaust resonator mod", anyone know what this is?

Thanks.

 

1) I've never encountered a left-hand thread on a Nissan vehicle. Righty Tighty, Lefty Loosey in all cases.

2) It's advisable to choose a meaningful Subject line when you originate a thread. In this case Catalytic Converter Questions might have been a better choice than Anyone know?

 

Daniel, thanks for the clarification on the first question. And thanks for the advice on the second one, it really helped me out.
