I have acquired an n51 (3 stage intake) with aa headers, pe, and aa tune. The seamless throttle response, power, and full throttle wail is perfect and intoxicating but the non-stop part-throttle drone is deafening and fatiguing. Is there a way to retain most, if not all, of the power delivery and top end sound while ridding the car of the drone? Removing the headers? Switching the exhaust? Tweaking the tune? It's a shame there's no free lunch but options are welcome.

Drone?

I have 3.73 diff as well and even cruising at 80 doesn't produce what I would call drone at 3200 rpm in 6th. Windows up. - quiet Windows down - riot |

Interesting. Yes, secondary cats and resonator remain. But even the slightest tip-in during cruise results in a cabin-filling hum that has to be shouted over.

Expected drone too. As others reported. So I bought a 135 muffler which is supposed to make it more civilized. I haven't tried it myself. But it's an option

But otherwise I dont think there's much you can do for the drone without giving something up. |

Go to an exhaust fabricator and ask for a drone pipe.

Drone here with stock n52 and PE exhaust.
It's only in the mid range, but it's a bit more than what I like, and my other car is just loud all three time. Looking to get more power and sounds in WOT without the drone. |
