ATMO when you don't need it, is for wankers.
You want to keep creating a bad image for all other skyline owners, go ahead. I'll sell mine and buy something thats image hasn't been f**ked in the ass by a whole heap of try hards.
I have a 300rwkw Skyline and I'm still running the factory BOV. Why? Because the car doesn't stall, the cops don't hear it, and so I don't look like a wanker.
Seriously, when was the last time chicks came running out flashing their tits and vaginas trying to get into your car because they heard the sound of your BOV? 98% of people that hear it think you're a try hard wanker. That is the complete truth.
No one cares that your car goes whoosh and backfires everytime you change gears.
