I am sorry you feel this way and have an unfortunate experience with our products. We have and many other shops in the US and Worldwide have used our titanium inlets and intakes without any issue. Our inlets and intake pipes are fused together without any filler rod. Additionally, the pie cuts are laser cut and cleaned, thereby not creating a possibility of slag. If there was a potential issue, I would be the first person to stand up and take care of the situation. It appears however that you had people working on your car which clearly aren't capable of the work they are performing.
I will respond to your points below:
1. Sent $8800 worth of turbos with cracked waste gate ports.
The Majority of stock manifold upgrades have fractures on the wastegate outlet port. This is normal and I confirmed this with a number of other vendors who make this style of upgrade. Nevertheless, I found a set of perfect ones off a 2015, had them modified, and shipped them next day to your install shop.
2. Compressor outlet didn't fit OEM hoses as advertised.
This was our mistake, we usually spec these parts with an intercooler piping kit and use the appropriate silicone but with stock piping, an additional pipe is needed. We payed for the fabrication for the additional pipe.
3. Wastegates were missing plugs, causing weird behavior.
We do not believe these were missing as we pack them with every kit. We believe your installer lost these and didn't install them.
4. Wastegate actuator nuts fell off during dyno testing.
Again, installation error. These should be tightened and pressure tested before installation of the motor into the car.
5. Wastegate actuator diaphragm turned sideways, causing it to stay open, mimicking a boost leak.
Again, install error, one that really tells the little knowledge the installer had as he bent the arm to sit improperly.
6. Welds that are so poorly done that you can cut yourself if you put your hand inside.
It is fused together pie cuts, this is normal and there will be some edges on the pie cuts.
I called you yesterday immediately when Jose informed me of your issues. I am 100% certain that our inlets didn't cause this and judging from the installation issues, it appears you just got stuck with a mechanic that didn't know what he was doing. After talking with you, i further believe this to be the case with all of the other issues and timeframe issues that became present.
I offered a replacement CHRA at my cost, and will still provide that for you. But I know this is not anything that is the fault of our product. I find the situation very unfortunate with all of the time and money wasted but hopefully the new mechanic you have the car with will be able to get the car running properly.
