Hey Mark, apologies as I dont hop on the forums often anymore.
The car has the following modifications:
N54 intake manifold
N54 throttle body
Custom 3" intake piping to OEM US airbox
K&N drop in filter
AA catless headers
S65 fuel injectors (for e85)
Secondary cat delete
Resonator delete
135i muffler
BPC pro tune
However, I just ordered the Magnaflow N55 135i exhaust which is downpipe back. But it will bolt up to the AA headers since they have the same flange. This will allow me to hopefully keep the sound down, shed some weight, and maybe pickup a few HP
