I Wonna go catless on my 86 NA rx7 do I just get a down pipe and test pipe or do I have to do anything else or have to worry about something

If u still have the air pump and it works you will lose the auxiliary ports because they rely on back pressure from the cats. Other than that nothing to worry about. So just cut them out if your auxiliary ports don't work

I have a Racing Beat down pipe I took off my 86 NA only has 8K miles, like new. make you a good deal. You will want the RB Presilencer as well. It has the Aux Port supply pipe built in to it. Worked great on my car. You can toss the Air pump and its related stuff. The ACV on the side of the LIM can go as well. Don't need any more as I'm going Turbo.

How do I know if they work because I want to go catless but I also want it running good still

Thebeastborja

So if I get the rb I won't have to worry abt the ports and still would work like a test pipe and were would be the cheapest place to buy one or does any1 have a used one

rotary_FD3S

How I did it is ( a little unorthodox ) rev the engine to 4800 RPM and look to see if the actuator to the auxiliary ports move.
Or try moving the actuator arms by hand

Thebeastborja

Ok I have a down pipe and test pipe not installed is there a way of getting the ports still working with these because I really don't want to buy something hella expensive but if I have to I guess

rotary_FD3S

You can wire the ports open but its possible that it would hurt low end driveability. What exactly are you using the car for?

Thebeastborja

Dam everyday driver drift and race alil so the racing beat prob be the best way to go

rotary_FD3S

I would spend a little bit extra for the RB then

Thebeastborja

Ok then so with the rb I won't have to worry abt the ports and still works like a stright pipe

rotary_FD3S

If it has the return pipe to the ports yeah

You can't drive on the street with no cat in Fresno.

Then just run a cat-back system. Use a high flow cat if you can.

According to the Racing Beat website (as far as I understood), you can only run a cat-back system on the street, as they don't allow any high-flow cats or modifications to the cats at all. You can only run a new cat if its CARB approved, and it'll only get approved if its OEM (or an OEM equivalent replacement). Someone feel free to correct anything that may be wrong; this was just what I was able to take away from what I read.

Aren't cars older that 25 years old exempt from emissions anyways? Idk as I live in Alabama and its no big deal here

Thebeastborja, do u by any chance go by the name thebeastborja on instagram? I'm one of your followers if so your FC is sick

Tunerguy21

I can't say for sure, but I don't think so. I think the only way an exemption would be considered is if its registered as an antique and wears antique plates. Even with that, you're limited to how far/when you can drive it if it is registered as such. That's how it works here in VA, at least; can't imagine it being much different in Cali. More strict, sure, but not much different. My .02.
