Hello everyone I have a 2002 Nissan Maxima and I am planning to remove the cat that doesn't have the o2 sensor in it and replacing it with a test pipe. What would the benefits be and will I get more crackle and pop? BTW I have a catback exhaust from the non o2'd cat.

Thank you,

Slightly louder with more rasp.

You need to delete precats.

Now how would I delete the precats and what would I replace it with?

Replace them with headers or pull them off and hollow them out.
