I just recently purchased a 3inch high flow catalyic converter ( rx7store.net ), and it doesn't have the passage for the stock airpump connection? I was wondering if it would be okay running this Cat without the airpump connected, or do i risk ruining it and clogging it up???

Thanks

3 minutes between post and bump?
search, read this... may help. https://www.rx7club.com/showthread.p...ht=airpump+cat

search took me less than the three minutes you took to bump this thread.

 

i read that thread and there are mixed opinions, not sure which one to believe?

anymore feedback is appreciated...

 

I have had a high flow cat with no air pump for over two years now and have experienced no issues what's so ever. Granted I only put about 2500 miles per year on my FD. Hope that helps you out somewhat.

Good luck.

 

He's not called shortfuse for nothing .

The cat will run cooler without injected air which may help the longevity of the cat. Most modern catalitic converters are efficient enough they don't need extra oxygen. Many FD owners have been running aftermarket cats without air injection for some time and some have lasted quite a while. The ones that failed quickly are more than likely because the cat was made cheap or the tune was making the exhaust temps too high. I think the whole clogging cat without air injection may be voodoo science. I was confident enough to run my aftermarket cat without air injection and have had no problems so far but it's still less than 10k miles but looks fine.

 

haha yeah I do have a Shortfuse when it comes to practically everything in life (jk)...

Anyways thanks a lot for the help, im confident to run my car without the Airpump now.

Thanks again
