Headers is probably the last thing you can do to increase power without going forced induction.

2014 E550-sold 😩
Makes no sense to spend $10-15K on turbos or supercharger when you can move on to the highly tunable 2012-2014 TTV8, where the horsepower gains put you in E63 range.
I would sell it.

Imagine its a same engine 5.5 as amg e63 2012 but no turbo on it plus its 4matic once u get e63’s turbo on it it’s definitely going to be better than stock amg!

Then go for it. E63's are all 4Matic, with different differential allocations to accommodate the massive horsepower. Personally, I think it's a mistake, but let us know where you end up as I don't know a single sole who has done it.

Full exhaust, 100 shot of nitrous and re-tune.

Yes, the tuner has to adjust the ecu tune to make sure fueling and timing are correct with the nitrous. Also use cooler heat range spark plugs with correct gap.

This is one option...it has been done on the 5.5L if you search around.
