im in the market for an N1 back box and b-pipe for my EP3 and just wanted to know a few things...
1. how much would both bits cost new and second hand?
2. would both bits allow me to go on track days within the DB levels?
3. is there any trouble fitting both bits to a standard manifold?
4. how much more power/torque am i going to feel when fitted?
