Ray. When I used to have my E-30 I started of with Stahl headers, they worked fine but they hung down kind of low, I eventually got tired of fixing them and changed to Supersprints they are a much tidier fit and gave me a lot more ground clearence, I couldn't tell any difference in lap times, so I would recommend the Supersprints, check with BMP. I also used a Flowmaster muffler.
