I got an 88 gxl with a custom cold air intake, and a corksport cat back. Which setup would be best? Will the 6 ports open, or will i have to wire them?

header is way way too loud. I have had both setups.

the header doesnt really add hp on the stock setup either

I think I lost some torque at low rpm when I went from the pipe and presilencer to the header.

heres a thread with a few ways of making the 5'th and 6'th ports act normally on an exhaust setup with low backpressure. if the ports are wired open, you will lose a lot of low end power.
