Test pipe question
In the last week I have replaced my stock mufflers with a set of magnaflows from Corvette Central deeper sound. and looks stock. Then I found a test pipe on ebay took off the 25 year old catalytic converter now it really sounds nice and I can really feel a few extra HP and the car does not seem to bog down when get on the gas at cruising speed.My question is the tube taht went to the converter I just put a cap on it at the point where in went into the fitting that was on the converter. Is this all I need to do? Should I plug or cap it somewhere else. I started to car before I capped the line and I could feel nothing coming out of or being drawn into the tube.

You could cap off that line or remove the entire line...either way will work. I do not think you will feel any air out of this tube at idle...only when crusing down the road...before the CCC switches the air to the converter. I maybe wrong on this, but I have never been able to feel any air coming out of the AIR pump on my car.

Unfortunately, I can't help on this Tim. My car was already de-smogged when i got it. I have no air pump, but I think it is basically just there to pump "cooler" air into the catalytic converter to keep it from burning up. You may be able to remove all of the air pump stuff completely, unless it goes into the manifolds too.
I remember that you wanted to try and keep your car pretty stock, so probably just cap it off.
