What do you need to know? I have sold and owned just about every decent E36 system on the market. In terms of power, fit, and quality Supersprint is the leader. They have multiple in-house dynos, everything is TUV approved, actually engineering, and works as advertised. For your E36 they offer everything from the headers back.
