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.

poor quality control, cheap flex joints

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?
