Yet more Exhaust Q's
I was just curious, I hear some people talking that some back pressure for a NA is good. So what would be the best combo or parts? Header/stock piping, catbacks, get rid of the cat? What works the best for a NA car...?

Hmmm, I've been searching and I've found many opinions on the Air Pump and Throttle Body mod and some others...but cannot locate the actual "how-to" thread. Can anyone help me?

AAHHHHH!!!!
back pressure makes torque, high flow makes HP (for N/A cars anyway). try to find a good combo. maybe RB header -> presilencer -> 2 inch dual, or 2.5 single(?) catback.
oh, with the S4 and the ports, you can wire them open or do some sort of electrical actuation crap.
I've never heard of an "airpump mod"

There is also another way to open them, and it costs about 100 bucks after you buy every thing. And it takes a 3 way air valve, an air horn pump, and an RPM switch. I will post the link to the site that tells you how to do it once I get home.

With just catalytic converter replacement pipe with presilencer and Racing Beat cat back exhaust sytem with the stock exhaust manifold would my 5th and 6th ports still function properly?
