High Flow Cat?

[Sparticus]

I have been looking at buying headers and wanted to get a Hight flow cat with it. But I really dont know to much about them. So here goes a list of questions

1. What will it do to the car. (gains, losses, and anything else)

2. Will it be louder.

3. Are they easy to install and are there any out there that will not set off the CEL

4. Where is a good place to get them for a cheap price that will work with borla gen 4 headers.

And any input is welcome. Thanks

1. about 4-6 hp gains. They work well with borla header to make good power though.
2. yes
3. yes to the install, kinda to the CEL. Cobb's causes a CEL, but they also have a 20 dollar fix.
4. I don't know about cheap. I bought from Cobb so it was expensivie.

Cobb's new custom one is not very expensive. $315 I think, compared to Random Tech. I had a random tech fall apart in < 6 mo. anyway. I haven't installed the new Cobb one, so I cannot vouch for anything, but they claim that it fits very well.

[Sparticus]

well that is alot more money then I was thinking they were going to be. I was thinking they were around 100-200. Well thanks for the info.

Cant you get high flow cats for like $50 from Summit??

[Storm]

Yes. A Catco universal (see also weld on) hi-flo cat is $59.99. Add in custom flanging by your local Midas shop and you're looking at about 1/2 the price of the Cobb or RandomTech cat (which is probably a Catco anyway)

All I have sat about car mods is most of the time you get what you pay for.

...and a lifetime warrantee is pretty good for $60. 'course you don't get the fancy name...

Dynomax makes a good high flow cat, and it's fairly cheap.

Here is one place (also the Perfection metallic cat is available from them).
Both are probably availabe at local mufler or performance shops.

edit:
Also note the link to their sister company http://www.discountconverter.com/


Anyone buy from either of these places??

[Albert]

I visited a few of their pages and found CATCO (ceramic substrate) cats for $40 but you have to purchase at least ten units.

****I called them and the sales rep says he can get the "newest" CATCO (metallic substrate) 3-way for $172


About how much is install if owner provides his own cat?


Update: The Dynomax site says their cats (ceramic) are illegal on post '95 OBDII cars. So... which cats can we legally use??

Just to let you guys know, one of the vendors is selling the 4th Generation Brullen headers for only $295 shipped. These are the latest from Brullen and they have taken care of all the problems which some of the earlier generation headers had. I don't know exactly which vendor. You might have to do a search under Vendor For Sale classifieds. I would highly recommend them and they also have a $10 CEL fix should you ever have a CEL issue.

Nope...not Brullen.

Rennick is selling the Borla for $295 shipped.

Rennick has/had one used Brullen header for ~$400.


**Also, who is selling the CEL fix for $10 ?

[Sparticus]

well I dont feel alone anymore, I am no the only one that has the same questions.

[Will98RS]

so is there any reason to get the cobb or random tech rather than getting a catco or another universal?

based mostly on the experiences of others wilth premature cat failure I would choose a metallic substrate cat over the less expensive ceramic substrate type. One major drawback with ceramic cats are possible premature failure if A/F ratio deviates much from stock. Either overheating from running lean or fouling from running too rich. Now if your plans don't include any mods that will throw the A/F ratio out of wack then a cermaic cat might fit the bill.
Price wise, just for the cat (some come with installation kit):
- hi-flow ceramic runs $50 - $110
- hi-flow metallic $140 - $190



Catco:
- ceramic:~ $60
- metallic: ~ $170

Xtremeflow:
- ceramic: ~$100
- metallic: ~$210

** Dynomax Super Converter are a good ceramic converter.
**Tennaco (Perfection) makes a good metalic converter but are hard to find.

And don't forget the direct fit prefabbed pipes from Cobb, TWE, ILP, and Random Tech: ~$240-$360.


Ultimately cash flow, your engine package, and good info from people you trust will make your selection easier.

I got my Random/Cobb cat installed, adjusted. I got a recurring CEL light for the first week & 1/2, then I bought a set of Denso Iridium plugs and reset the ECU, and I am STYLIN'. Great power, clean tailpipe, no CEL and schmoove. Get the cat, whichever one. I have the stock headers and I'm not sure I want to bother replacing them now.

PS - I know this has been addressed, but what practical advantages are there to wrapping the exhaust. I have the stock shields on the headers, so I was just thinking of wrapping the cat/mid/rear sections. Pro/Con?
