for anyone that has this drop-in filter.. was there a difference in sound vs. the stock filter @ high rpms?? just wondering..

 

I noticed a difference in the sound from the exhaust, definitely.

 

I noticed a little soft whine, a good whine. Like a turbo, only yet very soft. Only noticable in 1-3 gears, at low speeds. It's pretty nice in my opinion.

 

There's no real "sound" or "exhaust sound" difference, except for one thing, that the others have already pointed out.

It sounds like someone left a tiny "window" open in the air intake manifold... like a sucking air sort of sound that isn't present with the stock K&N.

With that said, I'm selling my K&N and going with a CAI.

Send me a PM if interested.

I didn't notice any change in sound when I had mine.

 

It's taken me a couple of days to answer this question as I only installed my K&N on Monday. Now it could just be that I 'think' I hear a difference because whatever it is - it's subtle, but after running it for 4-5 days I really believe there is a slightly clearer, more open, smoother note and I have to equate that to better engine breathing. Even if it doesn't do much to performance - I believe the K&N is a good investment if your not going CAI.
