I have an F-Sport Axelback with the secondary cats removed and a greddy intake. I have cabin noise but I wouldn't call it drone. I love the range of volume my car has. When cruising, its relatively quiet but as soon as you get on it, it screams.

 

hovik92, can you post a clip of your exhaust with secondary cat delete?

 

No problem. Give me until tomorrow and I'll have it up

 

I'll venture further and say deleting the 2nd cats. reduced drone, I'm on Joe-Z axle back. Like Hovik said, there is still cabin exhaust noise, but the booming drone is pretty much gone.

 

hovik92 and daobn24, do you mind sharing videos of your exhaust sounds with reduced drone?
Just curious about it

 

If you do not like the drone, drop the exhaust and apply some sound proofing up there. Problem solved.

 

lol
I already went back to stock, but I was just interested to hear the difference between deleting and not deleting secondary cat
