I've read that n54 is better, but never knew the full details.
Do you mind explaining ?

Thank you,
Well, long story short it has much more aftermarket products out there.
Many say it has much more potential. We honestly don't know the full extent of the n55's power, but the n54 has been very successful. The n54 also has the new single turbo system out there that can reach nearly 650 HP!

Many exhaust systems out there sound best on the n54 as well..
Basically you have 75% of the market in your favor. I would get the n54 just so that I can tune it more easily.
