Is there a picture of the OEM cat bracket that is needed to be reused? I'm getting my ART pipes put on this weekend and don't wanna go through any headaches.

Kind of hard to make out in this picture, but its in the bottom right, it connects both cats. It's really hard to miss when youre under the car.

glad everything worked out.

I contacted who i got the exhaust from and they are sending me out a new piece right away.. Still though if it happens again invidia needs to use a higher quality flex joint.. looking on other forums and searching the flex joint issue seems to be a semi common occurance. Thats what the flex joint is there for.. to flex from the vibration and movement of the engine if it keeps breaking because of that whats the point.

yeah its pretty clear that with enough abuse it cracks. I broke 2 driving normally simply because I didn't have that bracket. so far its holding up good but im worried about when I take it to the track or the extra stress from the super charger. if it brakes again ill likely have a shop weld in some custom flex joints.

The funny thing is there was no abuse.. I literally didnt even have the exhaust 1 month.. and there was no abuse

I had one pipe on for 2 weeks and it saw maybe 100 miles before it cracked, trust me I know how you feel haha

same here, after i put the test pipes on it wasnt 2 weeks before the flex pipe cracked. i recieved my new flex pipe in the mail wednesday. im going to try to put it on this weekend with the bracket.

Any body with the Gemini and ART pipes have this issue?

Tony@Motordyne says it not needed and docaam who has this setup says he didn't use it wuth no issue.

Hmm will this exhaust work with the tanabe y pipe?

no, go look at pictures of the exhaust and you will see why.

Oh it's an x pipe. I don't know where I read y pipe lol. I had an hks before in my old car. Now thinking of getting this since it's cheaper. Hopefully I'll have no problems.

Something inside of my muffler was cracked!! (test pipe and y-pipe on the car) It's making rattling noisy!! I took my car to dealer and they ordered new muffler for me and it's under warranty!! I have no idea how that happend..

im surprised the dealer warrantied your stock muffler since you have test pipes and a y pipe.

Because test pipes and after market y pipe have nothing at all to do with his stock muffler...

He was pointing out the fact that the dealer could have not warrantied the muffler because he modified the rest of the exhaust system. An upgraded y pipe and test pipes flow more air than the stock exhaust which could damage the stock muffler, and possibly did.

So, it's safe to assume that if you have your stock cat on then you won't have breaking or cracking issues.

for the most part I would say yes, you should have no issues. I still have no problems with the bracket in place.

im going on my second week with my new flex pipe and i have no issues knock on wood.

thats exactly what i was pointing out.

i had my gemini exhaust on for about 3 months before i put test pipes on and i had no issues so i would say thats true, but the test pipes compliment the sound very well imo.

Im going to be putting on the new passenger side pipe that invidia sent me today, so far the drivers side flex joint has been fine and its the passenger side thats leaking.

Just saw this.... I had an issue with the weld on one of the flanges that connect to the cat; it was only welded half way around and had a massive leak. Not sure how they missed that, but they sent me a replacement pipe, and I have not had any issues in the 5000 miles since installing.

I also have a loose hanger that is rattling on one side. I am not sure if the Z exhaust is the same (I have a G37 sedan), but the hanger on the muffler is 2 pieces and the part that attaches to the car slides over the piece that attaches to the muffler. On one side there is a weld holding the 2 together, and the other side is missing the weld altogether. Again just looked like over-sight on their (QA?) part.

Overall, the welds and quality look good, but I think, at least in my case, it was a QA issue. As mentioned, you get what you pay for. In the end, Invidia took care of the major issue, and at some point I will get a quick weld on the hanger to address the other issue.

So i put the new pipe in that invidia sent me and its STILL leaking.. the new pipe apparently leaks as well lol.. big thumbs down to invidia..

poor quality control, cheap flex joints :mad:

are you sure its a leak? this exhaust makes a hissing noise, in fact i believe all the aftermarket exhausts make that noise on the 370. at least from what ive heard on youtube videos. does it only make the noise when u let off the gas?

i meant to quote this message haha :rofl2:

Nope definitely leaking you can hear it just idling when you have it up on the lift.

maybe they sent you one of my old pipes :icon17:

haha probably

thats horrible haha. if that had happened to me i believe i would just take it to a muffler shop instead of going through them again.

yea.. dealer that i bought my car from is hella cool!! Plus dealer installed test pipe for free!! ^^ Nissan FTW!!

my dealer told me today that they wouldnt warranty my engine if something went wrong because i have a test pipe

For real?? wow.. My dealer told me IT doesn't matter what after market parts, as long as dealer installs the part, My car is under warranty!! Even turbo~!!! I love my dealer!! They r hella cool!!

hella cool lolz
