Remove cowl to hear more engine noise.
Unplug the diverter valves and plug holes its a diy blow off valve sound.
Good mods for the money:
Dci about $100 makes a nice sound and increases air flow.
Tune- $700+ best part about the n54 is tuning it! ( no dash lights, clears codes and its proven to be as reliable as stock)
Downpipes- under 400 for vrsf, reduce backprrssure, more sound and power, morr turbo spool!
How do you remove the cowl and unplug the diverter? Do you have a thread for those?
Lastly, where were you able to find a $100 intake?
Thank you for the help!
