Catalytic Converter

[Cyrk]

I am running Magnaflow cats... I am not sure which ones. I can try and find out the part #. They are a a universal size for the VX. They were about $180 per cat.

cyrk,
that would be awsome if you could find ANYTHING. i have looked for magnaflow cats, multiple places, and all i have found are "cat-back exhaust systems". im pretty sure, thats not what im looking for right now. i just need the converters themselves. im not being choosey here, ANY direct fit cat, and i would be happy.
also getting frustrating is searching sites that sell cats, click on cats, click year make model, then click search, and get to exhaust tips, and mufflers.....errrrrr, no cats anywhere.
well, thanks in advance for looking,
david

by the way, in my case, if the aftermarkets are getting replaced wth factorys,(whenever they come in ) i wouldnt want universal fits, right??? dont universal fits have to be welded on. thus loosing the "flange"? (i havent had a chance to ever see the converters in the vx....) OR would they cut the flange off of my old converters, weld them on the universals, then insall em.?
should i quit looking for direct fit, and think about univeral?

thanks again everyone..

I'd go universal in a heartbeat...check out the PAGES of cats on the Summit Racing site...LOTS to choose from.
Just crawl under with a measuring tape to figure out what you need (diameter/length)...any competent exhaust shop should be able to make them work.

Better yet, have the exhaust shop do the measuring & then have them check out the selection at Summit & make a recommendation.

If you hadn't noticed, August is almost half shot & you have been without your VX for FAR too long.

Good Luck !

This might apply to you or it may help someone else.

The warranty on any 1995 or newer vehicle's catalytic converter is 8-year or 80,000-miles. (epa federal law)

I found this out when I was searching for a replacement cat for my wrangler, I was lucky it feel into the warranty, Free Replacement.

mark,

yeah, thats what mine fell under too. 8yr 80000.... its just trying to find a cat that the dealer will install now......... . i gave the dealer a magnaflow number given to me by another board member, but that cat didnt have a place for the o2 sensor. so the dealer will not install that one.....i guess the o2 sensor HAS to be in the cat???? it cant be put in the pipe before the cat???? i just dont know anymore.

Sorry man, I call BS on the dealer.

True (if it was me you're referring to) the cat numbers I gave you do not have O2 ports BUT NEITHER DO THE STOCK.The O2 ports are before and after the cats on the pipe - see image below.


An aftermarket cat would be cut in and the stock O2 sensors would remain.


Let me know if you need more info or another opinion - I've gotten to know my muffler guy very well .

Cheers

kenny ,
if the cats were "cut in", what position would that leave me in when the factory cats come in, and the dealer installs them. im thinking thats the dealers hangup. i thouht there were flanges on each end on our factory cats. looking at the drawing you posted, i dont see what their problem would be either. and the guy i talked to at that number on the ad, had a cat without the stainless that he said would work. i gave the dealer all this same info, he said he would call me back if he found out they would
work.
isuzu does not know when they will start production on the re=engineerred cats.
isuzu will not tell me why they pulled all the cats off the shelves, leaving no parts redealy available for emmissions.
sigh................


tommorows friday, ..............time for another phone call, but armed with more info!!

thanks kenny,

[Kenny]

nope, the stock is not flanged.


Once you have a Magnaflow cat, why go back to stock when it's available? If I understand you correctly...

[IndianaVX]

that is what isuzu is wanting to do. they just want to get me on the road again with the aftermarket cats. i wont be holding my breath on the factory cats though, but yeah, they are replacing the aftermarkets, with new, re=engineered cats when they come in......go figure.......right now, id be happy with anything, as long as my vx is in my driveway again.........

While you're looking at this view, consider protecting that little crescent-roll shaped thing on the left. This is your transmission mode switch, and it's a common weak point of the VX. Some people have suggested some extra shielding on the exhaust pipe where it passes by. I personally haven't added any protection, yet, but I've done the switch replacement, and although it wasn't all that difficult, a couple cents worth of prevention probably isn't a bad idea.

I opened up my switch, and although I can't quite see what caused it to fail, blaming it on the heat of the nearby cat can't be too far off.

Thanks alot for the extra advice. You guys are awesome with additional info like this. It's like having our own shop online, and these days that's priceless!

You mean like this?

I've had a starboard side converter/Y pipe on order for ages due to torn flex section on mine.

I just received email from Sharff that its finally in stock, so if anyone else needs one, NOW might be a good time to order.

The old converter is going into the scrap, but if someone needs it for a flange or cat, better holler out.
