That should be all I need correct? I figured I would get a new o2 sensor as I'm pretty sure the one on there is original.

If anyone has any suggestions especially in the converter department let me have em.

 

I heard CatCo Conveters are good:

The exhaust is good

With the o2 sensor though. I would get oem. I had trouble with aftermarket o2 sensors, and the oem was only $50 for less hassle and oem plug in.

 

Good point on the O2 is it easiest to just order the O2 from acura?

Also, I was looking around on the catco site can you not order direct from them? Do you know any good suppliers?

 

catco or random tech are great high flow cats, magnaflow also has a deccent highflow cat, I have the catco. Def get an oem o2 sensor

 

i head people were having problems with the magnaflow one because it was trowing codes.

 

Yeah just go to your acura dealership for it.

you can search around for catco there should be a bunch of online sites you could get it from

 

You have to use the o2 shim just like any highflow cat

 

those highflow cats are universal right? so you need the bung to be welded on?

 

the universal ones yes... there are ones that are designed specifically for a vehicle though.

 

yep

 

 

Getting a bung welded in is stupid easy for anyone that can weld and they cost like nothing.

 

Instead of starting a new thread, i'll just contribute to this one. I was looking for a cat also, and saw some metal core cats vs ceramic core. I came across this insert while searching:

"Metal core catalytic converters are better than standard ceramic. More resistant to the effects of vibration that traditional catalytic converters and capable of holding up to high performance high temperature applications. 300 cells per square inch with a flow rate of 578 CFM which is up to 40% better than other performance cat converters on the market today. Suitable for engines up to 5.0L. "

Does anyone have a metal core cat on their car?

 

I did some reading about metal cores too. Supposed to last till they literally fall off the car. I ended up buying a Bosal however.

 

Damn lol. Sounds promising. How much did u pay for the Bosal? The metal core ones from vibrant are only $129 shipped from where i saw them for sale

It's direct fit and has the bung weld etc. It's ceramic though as far as i can tell.

 

Then again, i need mine for the prelude not the accord, so theres a difference. was yours 2 bolt or 3 bolt flange?

 

Just went and looked to make sure I told you right... It's 3 bolt flange on the back side. It's a direct replacement so I assume that's the same as stock cats.

 

what about the part that bolts to the header, is that a 2 bolt or 3 bolt flange?

 

The one I just put on was 2bolt on that side, 3bolt going to rear. So if it were a 2.x replacement, it would most likely be a 2bolt as well. This is just a test pipe that I have.

 

2 bolt I believe.


I couldn't ever find an angled photo.

It should be whatever the stock converter is.

 

The Magnaflow one throws codes because there's not enough platinum in it to convert the gases, that's why it's high flow. I've had this cat for two years.

As for the O2 and catback, why bother? I think it's a waste of money, especially for the new exhaust, our stock muffler is stainless steel

 

The kid that had the car before my put on an aftermarket muffler with some cheap piping and it all rotted out. I'm having pieces of the ceramic rattling all the way back to where I can reach in and pull it out of my tail pipe + rusted pipes all through + rusted out chrome trips so I just bought a new cat and a catback system.

I plan on having the car for a while so it needed to be done.

 

Are you guys seeing any CEL Codes with Bosal Cat?

 

It isn't installed yet. I decided to order some suspension parts and I'm gonna have everything installed at once.

It shouldn't through codes it's supposed to be an OEM replacement. However I can't guarantee anything. If I remember I'll update this thread.
