I recently acquired a 76 2.0L and am considering autocrossing it next year. I'm a bit concerned about the 88HP of the 76 vs the 95HP of the 73-74 2.0. I'm wondering how much of this I can get back by temporarily disabling some of the emission controls. Does anyone have experience with (1) disabling the air injector pump, or (2) putting in a cat bypass pipe (test pipe)? Does anyone know where I can get a test pipe for a 75-76 2.0? Or do I just need to get an exhaust from a 73 or 74?

Of course this will all need to be easily reversible.
