I decided im going to take out the 5th 6th ports, port the engine and bust the guts out of the cats, no emissions. I dont care about the low end power because from what i can remember from my first na all the power is up top anyway.

 

Your not gaining any power top end by taking the sleeves out. There really isn't any reason to take them out. Why wouldn't you want low end power?

 

It will make enough power to drive around and with porting an open exhaust for free, and it will be very simple and cheap. power will be better up high with porting and open exhaust
