I have a 86 NA rx7 and a test pipe is there a way to rig it for the ports to work with it instead of buying a expensive rb prsilencer

 

Hollow out a catalytic converter.

 

NA I don't want to do that

 

A RB pre-silencer is not even remotely expensive, and hopefully you figured out that you could just weld a pick-up tube onto your test pipe. Of course, this would be illegal for street driving in your area and you would never pass inspection with it, but we already went over this in a previous thread.

What kind of answers were you expecting? I'm just wondering how logic works in your mind.

 

That's all I wanted to know if I could weld it to the test pipe and I mean like more expensive then a test pipe it's not expensive i just don't want to buy something else if I already have one thing I could maybe work with

 

What abt the check valve that goes to the main converter that's what I want to know do I weld it to the test pipe or what

 

Does the car have a header? If so just tap it on tube number 2 at its highest point, use 18 inches of 1/4" copper tubing to dissipate heat and connect this to the inlet for the actuators. The pressure will open them, that simple!

 

Btw you will need a 1/4" copper compression fitting from the hardware store to make this work.

 

I thought the oxygen sensor goes there

 

Do you see what I mean
