So far my muffler has broke at the hanger welds and now their is a crack inside the flex joint in the Y pipe, all in 4,000 miles with no track time at all. The shop near me said the had another Z come in recently with a leak in the Y pipe on the same side, so clearly there are quality control issues.

I suppose you get what you pay for, it's the cheapest full catback out there, but IMO it's one of the best looking for that stock-ish look and sounds amazing.

Is anyone else having any issues with their Gemini?

UPDATE:

I figured I should update this since I fixed the issue, the flex pipe was cracking because I didn't re-install the oem cat bracket when installing test pipes. The extra flex from the engine without that bracket was too much for the flex pipes it seems. It's been several months since re-installing the bracket with no issues.

That doesn't explain why the hanger all the way at the muffler cracked at the weld, but I'll toss that up to a manufacturing issue and Invidia replaced it very fast. Still very happy with the exhaust.
