Hi-Flow cat- Use the airump or not ?
The cat I bought has a plug where the airpump goes.

Do I connect the air hose or should i just forget it and loose the airpump?

Depends on where you got it/who made it. The one that N-Tech sells I've heard doesn't need the airpump. If you got it from RX7.com, it apparently does need the airpump. And if you got it somewhere else, ???.

I would say yes. If it didn't need the AP then why go through the trouble of attaching the nipple?

The airpump will help your hi-flo work better over the years and last longer - but if you don't use it then it's no big deal - it will be years before you need to replace the cat again.

Assuming you are near the edge, you stand a much better chance of passing emissions if you connect the air pipe.
