Mercedes E550 Biturbo X-Pipe Exhaust (Stage 1 Tuned)

2014 E550 Biturbo (W212)
Stage 1 ECU Tuned
4.7l V8 Biturbo (M278)
---------------------------------------------
Stock resonator and Secondary catalytics removed
Stock resonator replaced with X-pipe (2.5")
Secondary catalytics replaced with straight pipes
(Stock catalytic converters and Stock mufflers still on vehicle)
----------------------------------------------
Sounds a lot more deeper and throaty at cold start and especially stepping full throttle. No noticeable drone inside he cabin, which is a big result from the X-pipe.
Why picked X-pipe over straight pipe or H-pipe ?
X pipe from my experience keeps the drone level low and gives it more of an exotic race car sound compared to the H-pipe and straight pipe. If you are looking to get your car louder with more of a deep raspy/old school muscle car tone id recommend a H-pipe or straight pipe over the X-pipe.

Future plans with exhaust
3" Catless downpipes to a 3" X-pipe or straight pipes down to stock mufflers, which should set me up for a future Stage 2 tune!
