Confused, Annoyed And Irritated
 

So just got my Motordyne ART pipes this afternoon and installed it almost immediately after.

I am starting a thread because after listening to that garbage(More Below) i cannot be bothered to read through reviews etc

So i have the Akrapovic exhaust, Its not loud but its beautiful nevertheless, Had a little muscly tone to it which i kinda liked, More on the silent side but great exhaust.

So after an hour and a half that the garage guy took to install,
I start my car and take it for a spin

IT FREAKING SOUNDS LIKE A FART CAN
IS there supposed to be some break in period, Because i paid a **** lot for a fart can (+ that retarded shipping amount)

I drove it home, Parked the car and got into my other car cz it sounded ****.
Please tell me this rattle that i hear from the exhaust now is just the car saying i am learning, gimme a few days ????!!!???
I am ok with rasp or drone, But this is just garbage

/rant

i would post a video but i hate it so much that i just ran away from my car 'embarassed'.

Help ?!??!?!?!??!

Exhaust leak? Or... Yeah... That's what happens when you remove the cats

They are not resonated so their basically straight thru piping which results in rasp :ugh2:

You will need to either use resonated test pipes or a HFC

To gain some horsepower

Aw come on..so this ART is basically an expensive fart can.
i assumed test pipes wouls sound this bad.
So i went ahead and bought this overpriced fart can.
Will upload a sound clip when i can, i dont want to go near my car currently hoping she changes the sound overnight or something
*fingers crossed*

There is a break-in, and at the same time some exhausts just don't do well with test pipes of any kind

I really hope its break in.
I would be glad if it would be just be half as bad.

Thanks for your replies though.
I m goin to drive with the music really high fr a few days and will update this thread accordingly

Ill save the next poor soul if this gatbage continues

Sub'd

so what is it? making rattle noise? too much rasp? I had a rattle noise too in the beginning, but it goes away after break in.

I really hope it is. Rasp is a very decent word, This can only be described as a rattle.
When i do go over 4k rpm,Then its very evident.Well i have driven about 50 kms, I guess break in period is more than that.

You know people put cans attached to this 'just married' cars, I have never heard one of those cars, But i highly suspect it sounds exactly like this.
Attached for better reference :rofl2:

Rattling? Are you sure your midpipe isn't hitting the cross member? It could have shifted out while installing your Art pipes.

Well i have considered the possibility but that would mean the sound should come all the time right ?
Not when i am only flooring it

I dont think it could be bad installation (I am useless mechanically so i am not defending myself :P but the guy who does all my work is pretty good) However I will be going to check again this evening just to make sure everything is right

This just sounds so bad. I am too lazy to get a video and i would have to get a drive by to actually make you hear that ugly rubbish noise.

Actually if the mid pipe is sitting a hair above the crossmember it would rattles once the heat causes the metal pipe to expand, at least in my experience that's how it happened on my car before I had it readjusted.

I have no clue what a cross member is

Can you explain to me so i can explain to the garage guy to check for whatsoever it is.
Its just frustrating lol

I secretely hope that this is some break in period so i dont have to remove it. I do 'feel' power but at the cost of a fart can on my car :S

I found this.

Can u take a pic or post a pic of the whole exhaust minus the art pipes?

http://www.the370z.com/1401480-post3.html
First picture, zoom in the middle there is a flat metal part in black that crosses your mid pipes }==|==[ hope this helps:D

OMG I REALLY HOPE THIS IS ACCURATE.
1500 miles is a **** lot. Long drive INC. Luckily petrol is cheap here :P

As far as the pics are concerned, I doubt i have a pic, Ill just attach one found on the net of my exhaust
(i has the carbon fiber one :D not important but i want to throw it out there because they are pretty):happydance:

Thanks for that. figured it out , Will check it in the garage later
I feel a little hopeful right now
Thanks for that guys.

Will update later in the night if anything is wrong with the cross member.

You dont need a lift to check it, just grab one of the muffler tip by hand and bounce it up and down, if you can feel it hitting or it's making a clanking sound then that's your problem.

Nope.
Soild. No movement, No sound.
I feel better that my 'guy' doesnt do these mistakes,
But i am still going to take up the car on a lift and make him check again.
But as mentioned i guess there is a breaking in for these ART's.

They seem like a great company and i woudnt want to be calling these things 600$ fart cans which somehow landed up wrecking my akrapovic sound too haha
(ofc i can just remove them but these ART's are all shiny and pretty. so giving them the benefit of the doubt and will keep driving em for 1000 miles. OMG FAR AWAY)

The exhaust is the problem. When u open up the exhaust by removing the cats or installing hfc you can get that fart can noise and some serious vibration and rattles. A lot of exhaust companies don't take in consideration if this happens. U need a exhaust that will be more compatible with your art pipes.

Would changing my rear part of the exhaust help ?
I dont want to invest in a whole new CBE.


Anyway Update 1 - 24 hours after installing the HFC's

Under 3k RPM, Shes deep, Not great sounding but deep
The moment i push it down, Cheap fart can sound.Rattle to be more specific, Its not a sound created by pipes hitting each other, The sound is evident to be coming out of my exhaust tips.

It's the design of your exhaust, it just doesn't vibe with test pipes. Either get rid of the test pipes or get rid of the catback for something like FI or ARK.

Are you sure or assuming ?
I myself have thought about this but cant really be certain of this since i dont have much knowledge on this

Theres several dozen people with ART pipes here that love them, and have no issues while using other styles of CBE. Im not certain, but clearly you dont like the sound so you have to make a choice.

I think it has something to do with the single muffler rather than two. Similar to a stock design.

Will wait for a few days for it to settle in.
If not fast intentions here i come

I ordered non-resonated test pipes andni have ARK catback, I think its going to sound sinister.

How are the arks ?
I dont care much for loud..the akrapovics fall on the silent side but they are deep.
I would prefer a little louder but something deep.
How are the arks when it comes to that ?
Sheesh exhaust shopping again i guess

If the H-pipe diameters are larger, it may make "whooshing" or rasping sounds.

If you are hearing a raw rasp/rattle on decel in particular, around 2 - 2.5 K, it's the ART pipes. I don't know about break in -- they are supposed to be designed with Helmholtz resonators, or so I thought...

If the rattle is random, try adding some thick rubber washers to dampen some of the vibrations (heat resistant stuff, like for high quality intake tubing, cut into sections) where the pipes may be making contact with the cross member, as someone suggested.

Good luck! Getting the VQ motor to NOT sound like a spluttering pick up truck is no mean feat...

I had very modest rasp with resonated (standard) TP's plus the (poorly quality, frankly) Nismo S-tune Weldina -- switched to OBX wider Y and got woohsing -- I've heard of similar issues on some H and X's as well -- went back to the Weldina, which suffered several leaks over time...

You might swap out the H pipe for a take-off Nismo one, or see about adding additional resonators somewhere in the mix -- there's a thread or two on the subject.

I like it, very high quality and the Grip has Helmholtz resonators in the back like the HKS hi-power. I honestly dont anticipate a lot of rasp once when I install the test pipes.

I believe the V3 ART pipes are not packed with fiberglass actually. That was for previous versions. Call Motordyne to verify, but I remember them posting that at one point.

I had V3 ART pipes with my Berk exhaust (after trying HFCs) and they added a little fartiness as well. It wasn't too noticeable so I drove with it for a couple years then sold em.

V3 Art Pipes have no fiberglass. It's the design of the exhaust. Put your stock cats on or get a new exhaust...

Well since more than 1 person has said its the design,

I am going to change my exhaust most likely.But only after driving this madness for a week to make sure theres no settling in.

My vote for a Motordyne Shockwave since you already have their Art pipe and manifold.

The Motordyne exhaust is not even close to being worth what they are selling it for... Sorry but it's one of the worst exhaust I have ever owned..

I am debating with myself.Hoping fora reply from Fast intentions

I dont really like to wait so

Fast intentions is apparently the best but i do not have the patience to wait.
I am looking for another exhaust, Deep but not too loud.
Louder than Akrapovic though.

Funny though..bought akrapovic. Loved it. Bought art pipes hated it. Buying new exhaust..hahahah my logic hahaha

Will be buying fast intention cbe 18" resonators.
Lol 3 months from now ill update this thread haha

You won't regret it. And its worth the wait. It only took 3 weeks for them make my test pipes, maybe it wont take so long for the CBE

Just curious what issues did you have with it? A couple i heard in person sounded very good. It's one I'm considering getting next, currently I have Ark Grip and DT-s

You need to wait for the carbon build up to lessen the rasp. Take about 2 weeks. Just like a rifle
