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 |
