I'm looking to replace my midpipe with a hi-flow cat.
Any recommendations? I'm looking at the RE-A one on rhd. But I need one that will definitely work without the airpump.
Sorry if this has allready been covered...I can find plenty of threads on cats, but not on ones compatable with the air pump deleted.

Cheers

Tom.

 

bonez

 

Awesome - thanks. A hell of a lot cheaper too .

 

I have a Sard, very happy with it...albeit for a short time

 

Are you running that with or without the airpump?

Also regarding noise...The louder the better..I love the sound of a midpipe.

 

Do some research on the SMB metal cat from SMB in AU.

 

I have a Bonez on mine and will be removing the airpump as soon as I get the airpump idler pulley kit from the group buy here on the forum. I was talking with mrb63083 who ran that setup for quite some time with no problems.

 

Just keep in mind that without an airpump, the environment for any cat is rather harsh. Getting the best quality cat and good tuning can help it last.

 

What he said. The cat with traditional cores require the air injection at that precise location to work properly. Not adding that extra air often results in decreased life.

The high flow cats using 'metal' based cores do not require the air injection.

There is a thread that I posted in a couple of years ago that has a lot of this info if someone cares to research it.

 

SMB. Can be ordered with air pump attachment.

 

Yes I have the airpump

 

I'll keep that in mind. Thanks.
Would you recommend a Bonez? My only concern it that it seems a lot cheaper that the ones on rhd...

Cheers

Tom.

 

I used the Bonez for many years. It's not a metallic substrate but it's probably the best ceramic based cat available for the FD.

 

Thanks - I'll look into it

 

Kyle,

This was without an airpump right?

I only ran for a little over a year without the airpump on it. Still, the cat looked clean when I sold it.

 

btw, im running no precat, 3" dp with bonez high flow cat and i cant even enjoy my music anymore because of the noise, even at idle its still growling

 

I am running a hks dp with a bonez hf cat air pump attached and 3 in trust exhaust. nice low tone growl. sounds mean..... who listens to a stereo in an FD anyway ..(LOL)

actually it just calls for a better sound system or an excuse to spend more money on the FD . it did for me at least.

on topic... ran a bonez hi-flo for about a week... then returned it to my cousin. i liked it. none of the stinkiness or smoke like my newly installed res mp. the HF is rather loud in comparison.. but its nice loud(low/deep growl). i didnt expect my res mp+apexi gt to be quieter than stock+gt/bonez+gt. if i had time+money to do it all over again i'd go with bonez

 

I love to listen to the motor and turbos when driving my FD its the only music you need. but having a nice stereo to show off is a great add on as long as you keep the interior stock no extra speaker boxes mounted inside the car just my opinion!
