Nah, you're good :)

Cool, thank you!

Trying to figure out if I should get these ART pipes or go back to stock cats... I love the power from my non resonated test pipes right now but the RASP is killing me. Drone I can live with. I have a t1r catback and right at 3k if I step on it more than 30% throttle I will get this huge raspy explosion of sound and power too -_- Sounds like I'm driving a Civic hitting that vtakkk bs. Would this cut down the rasp to around the same as the stock cats would, or would it still be considerably raspy?

The rasp I have to deal with right now that I really do not like. More noticeable in higher RPM's, the exhaust is supposed to have a very deep tone by itself but definitely not anymore with my test pipes :(

That doesn't sound too bad on the camera you're using, but ART pipes will cut down significantly rasp you're having.

Installed my ART pipes this weekend. Called Motordyne for a quick question, they said Tony would call me right back, and he did. He basically ended up walked me through everything before I started and told me to call back if I had any further questions, really appreciate the awesome customer service! Anyway, I drove the car to the on base auto hobby shop so everything was hot. I figured I'd just break the evil bolts, which I did, and fairly quickly(took a while since the shitty socket kept falling off the extension) I'm not a big strong dude either, just a good breaker bar and some effort. One tip though, i put the socket on the drivers side directly on the bolt and then fished the extension in. (about 30 inches of 1/2in extension) and then hammered lightly to make sure it was seated next to the steering linkage, and proceded to snap that bitch off. it helps to have a friend keep pressure on the end of the bar while you pull, it does come off with a bang. then came loosening the stock bolts which was time consuming, one because **** was hot still, two because some of the bolts arent easily accessable, but not bad at all. all in all, it was 4 hours with moving my car in between, and by myself with shitty tools. reset the ECU, let her idle for a few minutes, enjoyed the smell and took her out. was easy on the gas for as long as I could stand to let the ECU remap and then romped on it. initial impression was some rasp, but it sounds great w/ just post maf tubes, drop ins and stock exhaust. definitely louder, but not bad. sounds mean WOT. no pictures as i'm posting from work, and its been too rainy to really tell how much power I gained but ill tell you this.. rolling on the gas in 3rd in the wet now lights the tires around 4500rpm. good jump in butt dyno happiness and noticable tire spinning power, so I know i'm not fooling myself. Thanks to Motordyne and Tony :) now I want the Shockwave too. haha :shakes head:

Can someone confirm that HR ART pipes don't fit the VHR engine? haha

I ordered a set from FBNissan on December 13th and received the shipping info on Friday evening (Dec. 21st). It says HR ART pipes are on the way to my house.

I explicitly stated that I have a 370z and I was in communication with FBNissan through a little forum called the370z.com so surely they know what engine I have..

afaik, test pipes off the 3.5 HR motor should work on the 3.7 VHR

iirc the 3.7 VHR is the 3.5 HR just bored out a bit more

someone else chime in if im wrong

Can someone clarify for me, are ART pipes ok when used in conjuction with a supercharger setup, or any forced induction for that matter? I just read that RTP's aren't advised for boost, but wanted to double check on Motordyne's ART pipes to be sure...
Thanks! I'm beginning my mods and want to leave my options open for FI in the future

Yes, no problem with FI on ART pipes.

hey. i have a 08 g35x sedan and i just ordered art test pipes for my g. i told them i had an all wheel drive and that it was an auto so they said i would neeed the one for the hr motor, they did not say anything about it no being compatible with my all wheel drive. i was browsing through the site and happened to see that it does not fit on the awd...so my question is did i just buy something that is not going to fit or did u guys fix the problem since its already almost two years later? i searched on forums and i see that you guys are looking for lab rats for the test pipes. i am interested but i already bought mines. i should get it in the mail sometime next week. but will it fit?

hey motor dyne. I just purchased art pipes for my 08 g35x awd sedan. i mentioned it was awd but they did not tell me anything about the art pipes not fitting properly. Has the fitment problem been addressed now? willl my art pipes fit perfectly on my g35x sedan? or is the promotion where i get a discount and full money back guarantee if they d:confused:o not fit still going?

i just bought art pipes yesterday but they did not tell me they would not fit and i explained i had a g35x all wheel drive. has the issue been resolved? if not i would like to participate. can i still get the discount too? i payed full price:confused:

You are best off calling MD directly to ask if they know for sure, i can't remember if i've seen the answer anywhere.

Recently I purchased those ART test pipe from an authorized dealer . After installation , I noticed that right pipe (passenger side) is hanging down MUCH more than the other one . so I contacted Tony at MD and I explain to him this and i attached some photos , he said " the location of the passenger side (right side) ART pipe is correct , and it must be that way out of necessity of clearance on all makes and models of coupes and sedans " !!!

Right now the ART pipe (right side) almost scrape everywhere .


I had many HFC's and test pipes none of them had such fitment issue.
What do you guys think ? is this alright and it should look like that ?

First 2 pictures with Berk CBE and the rest with stock exhaust .

Thanks

Wheres best place to buy their (motordyne) exhaust system?

I'd contact Jomer for best pricing from fredbeansparts. His username is FBNissan.

It looks like the resonator section isn't at the right angle, also remember you have rotation adjustment on the ART pipes, try resetting that first.

What do you mean by rotateing the pipe ? The right resonator itself hanging low , the other side is ok . Even with rotation which I doubt its possible still it will hang low.

The ART pipes are adjustable via rotation on the headers, it affects the height of the y-pipe end under the car.

I just got mine installed on my Stillen super charged 370z. Before I had invida tp but they cracked twice for no reason so I went with the motordyne. I also have tanabe exhaust. These are way quieter than invida. That can be good or bad depending on what sound you want.

In your pic you are missing the support brace that attaches to these, if you don't install the brace then these will crack too. I'm planning on getting these in spring so then I should be able to get a 12.9@110 at the drag strip.

I actually put it on right after this pic was taken but thx for the heads up.

It seems like these tp's are lower than the invidas I had. I hear it hitting when I go over speed bumps where before with invida nothing hit. Does anyone know exactly what is making contact? Is it the reinforce bar that goes across the tp's? I also liked the sound of my invidas better. The only problem is that there welds keep failing me. These motordyne are almost to quiet.

yea they are pretty damn quiet. I think the lowest part of the ART pipes are the ends of the side-branch resonators.

Since the ART pipes use the oem donut gastket, they can pivot on that to change the pipe's angle relative to the header. For example: if you tightened the bottom two bolts on the triangular flange, then went to tighten the top bolt, it would result in the ART pipe being angled downwards too much. Its best to get the pipes sitting how you want them, then tighten the 3 bolts on the flange equally.

^^^^ That, also, make sure there isn't the floor shield bolts sticking through, i don't know if it exists on the 370, but worth checking.

Difference between the v2 and v3 ART pipes?

I believe it's just brackets.

How in the world did you manage to reach and get the very top bolts out on the factory CATS ??? Almost no access to them especially the driver side. 45min you said, and you did that on the ground!!???? It's the worst designed access for CATS ive done. Impossible to get them without 2+ foot extension which you gotta use from the engine bay side

Yes, that would be how you do it.

I wish someone would say something about it in the installation thread. I never came accross this info. 2+ foot extension is not something many people have and even techs.

Anyone know if these ART pipes will work with either the FI TT 3" exhaust system, and the AAM TT Kit?

I have a set of motordyne art pipes installed in my 09 370z and was wondering if its normal for the car to make a hissing kind of sound after letting off the throttle. started happening after I installed the pipes and did not find and leaks when i felt around them.

Yes, it's normal.

My flex pipe broke with my current setup AAM Comp TP + Beluga Y + Beluga Catback
