- It's not compatible for the N55, Convertible or Xi Models
**Edit -- 91Octane nailed it on the head... HPF & VRSF designs mirror each other. A single 3.5" exhaust pipe that separates for the dual exhaust tips. |
Ours doesn't sound like the HPF nor does it look like the HPF. We utilize a muffler rather than a straight pipe and our exhaust has about the same or a little less drone than the AE at low RPM. I've never personally tested the AA so I can't comment on the drone against that. Just because we chose the 3.5" single pipe route, doesn't mean it's a HPF exhaust. I believe AMS also went with the 3" single rather than 2 2.5" pipes which everyone seems to be doing.
The general area of 2 2.5" vs a 3.5" pipe is almost the same but you have the benefit of a huge weight reduction which will absolutely benefit the car all around (handling, acceleration).
