ECU + Exhaust system for X6 5.0i (Advice needed)
Hey folks, hope all is ok. I'm willing to install an exhause system + ECU tune and I really don't know what you guys would recommend.
What I need is a quiet exhaust system + super powerful, easy to install ECU tune.
Appreciate your assistance.
Thanks,
Massa7
