ARK PERFORMANCE INC : 370z TRUE DUAL Prototype Teaser w/ dB Test.

Neo187H · 09-21-2010, 05:16 PM

Since you told me the issue was an incorrect install I took the time to take the exhaust back apart and lo and behold the midpipe where it connects to the X pipe is indeed warped, I'm trying to get pictures of it that will show up on my phone camera though it is proving quite difficult.

TeamARK · 09-21-2010, 05:19 PM

email me those pictures directly to alex@arkperformanceusa.com so I can guide you with the install.

I don't know how the Xpipe can be warped.

didnt get a pm?

Here are some detailed installed pictures. This was done with the same batch that all ARK 370z exhaust came out of.

Enjoy

The install went flawlessly other than this, took a whole of 35 minutes from start to finish. I really don't mean to make this a larger issue than it is, sorry I got my feathers ruffled a bit with your response.

I misspoke, its the pipe that connects to the x pipe between the muffler and the x pipe, the flange where it meets the X pipe WAS warped. I took a large grinder to it and took off maybe half a mm of material off mostly the ears and it seals perfectly now. Like I said before, the leak was very small and didn't even cause any noise just some minor flow was felt from it while leak checking the system over. But the small leak has now been corrected without spending any money or really any hassle at all, I just wanted to note it as it really was my only concern with the exhaust system as a whole.

Please don't get me wrong, I am a VERY satisfied customer, anyone that has heard the exhaust has said thats how it should sound from the factory.

Edit: I will send the pictures out once I get home and able to upload them.

Installed the GRIP type 2 exhaust on my Z tonight, exhaust looks great, sounds great.

One problem the exhaust seems to be hitting the cross member on the passenger side, just like the guy in the previous pages. I was worried about the gap between the x-pipe and the cross member when I put it together, but it didn't come to close, after about a 40 minute drive, it rubs under decel and idiling.

I suppose I need to get back underneath and try to use a jack raise the x pipe.

I will let you guys know how it goes.

Update:

As a quick fix the next morning after my post I spaced the cross member down about 5mm to stop the rattle.

Since then I have been driving with non resonated test pipes and the exhaust, and WOW, on acceleration it is very aggressive, ie pretty loud! Too loud for my taste for a daily driver, even a weekend car. One thing that impressed me though is the muffler itself. When you accelerate it screams, but when cruising, over 2500 rpm it is nice and quiet, near stock quiet. Below 2500 rpm while cruising it drones just barely.

Keep in mind that the test pipes were the main contributing factor to the volume. I finally had time yesterday to install the cats and adjust the exhaust to clear the crossmember correctly.

On a stock Nismo, only mod being the exhaust, the volume now is near stock.

I didn't dyno because I got too excited. Once I had the box, I was doing the install.

You have to raise the midpipe and then bolt it up. It will hold just fine. When adjusting, you can push it all the way to the top so that there is room for play when you tighten it.
