E53 tuning

All in all, unless you floor the car regularly it may not be worth the $2500.
Case in point - I’ve had four BMW Five series cars with different engines. NA Six, Turbo Six, V8. Surprisingly all got about the same gas mileage because I just laid into the gas on the less powerful engines more to drive the speed I wanted.
I switched to a E550 Cab and now a E53 cab, so I like fast and the higher performance trim looks better and sounds better. Maybe you would get pleasure with a new performance exhaust.
