Pops and burgle = bad?

brianx42 · 09-26-2017, 12:03 AM

I have AAM Comp non res TP with tomei catback exhaust. I've noticed that I have been getting a lot of loud pops and burgled when shifting from 2-3rd and 3rd -4rth and sometime downshifts from 6 to 5th. The pops mainly happen when I'm just cruising and holding the rpm around 3k for a lil then clutch in clutch out and pop!

Is this normal? Should I be worried of damaging my internals?

Side note: I don't have my o2 sensors on my cats plugged in because they're stuck on my oem cats. Placed an order on aftermarket ones only to find out that it doesn't fit. I have the small caps to cover the o2 plug currently.

you have ot have rear o2's. Otherwise the car (including the 350z) won't run right. Believe it or not, the secondary o2's do more than just checking the cat.
