shouldn't the o2 bungs be located before the cats?

or am I confused? (either in that statement or in looking at the pics)

 

They are for the rear O2 sensors. They go after the cats.

 

Is there ANY and I mean ANY rasp whatsoever on these hfc's? Im considering buying these

 

The CATS themselves do not rasp - but other pieces of your exhaust system may cause rasp do to the increase in flow and sound characteristics. If the system can't filter or handle the flow properly - ANY cat will rasp.

We have yet to hear from a custoimer that the CATS rasp at all...

cant say. i dont have a resonator so my exhaust already had rasp prior to install these.

 

Did the rasp get worse or lessen at all with the CATS?

 

Why not get a hot dog. https://g35driver.com/forums/showthr...ight=resonator

 

with the cutout open, its much much much louder and much much much raspier.

with the cutout closed, not much changed. not much rasp for daily driving, if any at all, but when i step on it...raaaaaaaassssssppppppp

 

did you read this guys review?

 

I so love that thread - Hot Dog - that's so funny how some can't realize it's called a resonator.
