So i was just looking around on ebay and someother sights... I was looking at uppipes and i noticed that some have the flexable middle sections like justins and some dont. So my question is what is the difference?
your engine, exhaust and turbo shake, it is all normal with everything going on. This helps prevent leaks from appearing over time. Many people are fine with non flex versions, but some have issues. The stock up pipe has a flex section in it.
