I got one from a 2011 E89 Z4 3.0i, before they went 4 pot turbo. Looks decent but I'll probably end up replacing at least the inner one before install.
Should I pay someone to flash to E89 Z4 code? Or should I get Tuning service from ECS aka Turner Motorsports? Is there more power to make with tune? Currently on OE header and will be for a while until clutch replacement in 20k miles or so.
