so ive been working finally and had some extra money and decided it would be a good idea to replace my cat so i did. truck runs a little better now and now has a little deeper exhaust sound its nice.

 

details details. What did you get and how much and where?

 

I just got a MagnaFlow high flow cat from "Performance Curve", an eBay vendor. $56 shipped:

(that auction's done, but hit "View seller's other items" to find a new one)

Great price, Immediate ship, perfect condition. I'll hopefully have it on "soon".

 

Hmmmm, isn't that a universal fit? Did you have to cut off the mounting brackets of your front and rear pipes and then clamp it on?

 

yah i'm trying to figure out the same thing, cause i've got a new 2.25" exhaust and now want a new cat, but i was hoping for something that would bolt on using the stock flanges. also, should i get a 2"in, 2"out cat? or 2.25in/out?

 

i thought the toyota stock size was 2.25", but you may want to double check that

 

its 2" on 2nd. generations. i'm not positive about 3rds though.

 

You can get all different sizes from ebay. Just note what you need and do the whole "view sellers other auction" link like Mark said.

 

Yeup, 3rds are 2.25" stock.

I went with 2.5" 'cause when I put headers on I went to 2.5" pipe from the cat on back to the tail, and the shop kept the stock cat. The way it is now, I have a 2.5" -> 2.25" reducer from the collector to the cat, then a 2.25" -> 2.5" expander from the cat to the exhaust. It's a bit Frankenstein...

The Magnaflow cat shows up just like it shows in the eBay pic. No flanges, and it's about 1/2 the length of the stock cat. That actually works out pretty well for me, 'cause when I got the headers put on, there is only about 4" of pipe from the end of the collector to the cat. The front O2 sensor is real cozy right there, and my wideband is cooking pretty well - there's a lot of heat at that point.

Anyway, the sort length of the cat will let me extend the run from the collector which will open up some room in there.

 

Mark, is this the same cat you have..? http://cgi.ebay.com/ebaymotors/ws/eB...RK%3AMEWA%3AIT

I was going to get one this weekend and was wonderin how did you connect yours?
Any chance you have some pics?

 

It's the same cat in that it's the Magnaflow HighFlow universal, but I bought mine from a different vendor (see my link above) and it's a 2.5" cat (the one at your link is a 2.25").

Mine isn't installed yet... I have two people that are willing to do it (or to put a torch in my hands!) and we have to work out a schedule. In general, mine will be welded in - I don't like clamps in an exhaust system. I have enough problems keep flanges sealed, I don't want to fight tubing clamps as well.


Christian ("<96 Runner>") is the guy that started the current cycle of the "Magnaflow HighFlow Cat" craze. He recently got one from the vendor I got mine from and I think his is already installed. He may have some more words on how to make it happen.

 

i just got a universal one from buckys and had them install it it only cost me 140 dollars all together and they welded the new cat on so i didnt mind paying that much. also if i would have waited longer or not noticed the smell it could have been alot worse then just spending 140 because i asked the guy when i picked my truck up how clogged the old one was and he said about 3/4 of it was clogged not much flow there.
