Gee whiz old man - don't act like I'm the pain in the ass that I am - surely you knew that when you sold me a car?
Anyways, question is this: there is a shitload of piping on the GTR; balance pipes between the turbs, etc, etc. Makes working on the car tricky & ppl tell me that it is mainly for emission control - can you tell me what can go & what needs to stay in order for the engine to run properly?
