I don't need to pass emissions, just need a cat for visual purposes and I don't have a smog pump. Does anyone make a high flow mid pipe without the air tube? Thanks.

 

Just run a dummy tube to it

 

You could purchase a metallic substrate cat, then just cut a midpipe and use bands or have it welded into place. They won't do much for emissions, but if you only have a visual check they are technically a cat.

 

Just buy a resonated mid pipe. They won't know the difference as long as it looks like a cat.

 

You could have one custom built without the tube, or just buy one, cut the tube off and have it welded shut.

Will a high flow cat burn up or anything without air supplied to it?

 

This is the route I was considering if there is not off the shelf solution. It's cheap and clean, just a bit of extra work.

Jason, I have a resonated MP. Between the smell and overall appearance of the muffler... I can't imagine it would fool anyone.

 

I bought one off RX7store.net and the tube for the air pump was plugged off, I had to have the pipe removed off the old cat and welded onto the highflow at a machine shop.

 

No, the airpump is for emissions. I guess it could help cool things off, but its not necessary.
