As the saying goes...you got to pay to play! It just about how much is it worth to you. We are here to help you spend your money, LMAO!!! I have gone past the rabbit through the worm hole and into the black hole. I see Spooler as he is keeping me company.

I just moved back to the same area I shot this video. This spring I’m going to go back and re-create with my new setup for direct comparison.

That is still my favorite exhaust after all these years. That is why I have a Carbon Fiber muffler 3in. exhaust on my car now.

LOL, Yeap we are racing the black hole.

For deep note you need resonated system, I have Fast Intentions with 12" res and motordyne LTH with resonated module (very close to johnny car)

This is the best clip I could get for outside sound.




But it drones, I don't know if 18" res will be drone free, a friend said his HKS hi power doesn't drone, and it is very quiet until you slam the throttle.

I have the greddy evo gt with ART pipes, not Supercharged, and it definitely drones. Which is unfortunate because it sounds amazing above 3k and WOT. I can’t wait to hear it fly by me or what people say when i take it to the track. There is a narrow rev range where you can eliminate the majority of the drone, or just stay above 3k ;), and depends on what highway speed you go because i think 55-65 is drone. May be high too, I don’t remember.

Sometimes i wonder if my ART pipes are real because it has so much drone and people claim ART pipes reduce drone compared to hfc or test pipes, meaning their heads probably explode on a daily basis.

The idle and natural backfires are nice

I have Greddy GT also but I have FI resonated test pipes and while there is drone - like you say - it’s not at all bad - and it sounds aggressive and deep when you WOT.

I read somewhere catbacks are more responsible for drone, also engine mounts play a part, it was very good when I had stock mounts, with solid mounts, it became a lot noisier inside.

Man this video is making me second guess wanting a motordyne. I'm seriously torn on the motordyne over the fast intentions. My plus for the motordyne the sound is exotic and no drone negative is I've heard it's insanely loud and don't really want to have to deal with getting a ticket for it. The plus for the fast intentions is it sounds deep, and it's quieter (can anyone give me a good idea of how much quieter?). Negative is the drone at cruising speed. I've watched every video and still can't decide.

This is the video that convinced me to go with the FI CBE and Berk cats. Listen to it with headphones or on a quality audio system. Although he doesn't' state it, I believe this FI setup is using resonators. I say that because mine sounds even louder and meaner.

I thought ART pipes remedied rasp rather than drone. I had ART pipes with my Top Speed exhaust and Motordyne exhaust and it deepened the sound from my Circuit Werks. I did not have drone with either exhaust also. I drive 120 miles daily for work and its mostly hwy so I stay in the 3k-4k rpm range. But I also have a G37 so maybe the extra sound deadening makes the difference.

I loved my Motordyne exhaust on my G37. I think paired with HFC, sound volume won't be too bad.

Motordyne is the way. I love my shockwave. I'll be ordering either art pipes or lths with helmholtz resonators this spring. i'm just not sure how much work i'm ready to do. look up 370z motordyne exhaust w art pipes on youtube. that sh*t sounds so nasty.

I had a Motordyne CBE on my 350z with Art pipes, and my wife has a MD CBE on her G37.

-If you're keeping stock cats, the drone isn't bad, although it is definitely present.
-If you're getting rid of cats, expect drone at highway speeds.

It is significantly louder than a Fast Intentions. My FI even with long tube headers is about 82-85 dB inside the car with the tester near head level. I'll check my wife's car, if you PM me a reminder, but it's not much quieter and she's inside a better insulated cabin and still has OEM cats. I'd guess my 350z was 90-95 dB under load.

:iagree: I love mine as well, but yeah, around 55-65mph(2500-3k rpm) it does drone. Currently running ART pipes too, but switching to FI resonated TPs in a few weeks.

Thanks guys for all the info. All this is very helpful.
