I ordered this to replace the flex pipe section on the Eurojet Gen 1 turbocharged rear exhaust for a 2007 VW GTI. My mechanic asked me to get a flex section that's a little larger than the existing one so there's a little more room for error when cutting the old one and welding the new one on. It worked great. He said the installation was a bit tricky as there was only 3/4 of the pipe to weld after the flexible section. He also noted that it was a much better quality than what he was used to from coiled tubing. My exhaust sounds like it should again and I'm not embarrassed driving while hearing like a straight pipe diesel truck!
