Trouble finding twin cats
 

--------------------------------------------------------------------------------

I have a 96 lt1 trans and am looking to purchase two hiflow cats for when I get the headers installed, problem is, I cant find any. every distributor page I have has cats for 93-95 lt1's or ls1's only. i found a few universals but i'm not sure whats what anymore. I have the 1 3/4 inch slp shorty (some say mids) http://www.slponline.com/view_product.asp?P=30017C

it doesnt say how large the tubing is on the headers but i assume where they match up with the cats is factory manifold size (whatever that is, 2.25-2.5"?) since they are designed to mate to the stock cats? so i have no idea what size cats i should get if i have to get universal highflos?

See the Random high flow Y-pipe on the link below. You might still need the SLP adapter kit? I don't know of anyone that sells just hiflow cats for the dual cat LT1s as they have an odd bend on the drivers side. Only thing I've seen high flow is the complete Y-pipe.

did you check summit yet?

**** thats expensive... looks liek it moves the drivers cat to... a no no for visual inspection :(

actually, i doubt that they could see the drivers side cat where it is in the factory location....

yea i had to buy both of those suckers, it was like 300ish bucks. whoopeedoo! :(

Did you find just the cats or did youget the whole pipe? seems like an aweful waste of money to have to replace the whole y jsut to get hiflows

i was in a hurry so i just bought the whole pipe. and yea i do agree that its a waste of money to just get cats...

What else have you done to your car?

At QTP we use Magnaflow Cats they are 3" OBDII Universals and they sell for $50 a cat. Were actually working on producing our own catalytic converters to use with our Y-pipes that are very similar to Random Tech Bullet Cats (300cell)

Isnt the ypipe 2.5" anyway?

I got a compact 3" cat from Pypesexhaust.com for the driver's side and got a 3" Catco cat for the passenger side. I got them off Ebay so my net cost was like $40 for both. I cut the y-pipe and clamped them in but ended up having the driver's side welded for another $40. Here's my y-pipe with dual 3" cats on my 96 SS.

that poor SS... :D

Gutted cat ftw!

then you need to pay the money for O2 simms with OBDII

technically...no...have no more cats on my car, and no more rear 02 sensors and it runs fine...i have the sims, just never installed them yet :rofl:

if you buy cats they are gonna take a **** on you after you put a cam in your car. cam + cats = crap

what do you mean?

Only if it's tuned to extreme lean will it kill the cats. Too much heat in the exhaust will melt the cat's internally.

go on ebay, magnaflow carsound highflowss are like 65 bucks a peice, part number 94109 is the best ones they are 3" in/out shortys

that's what I bought for my 95...

just got 2 2.5s from eBay, bnib...54 each, for my Lincoln, gonna have them welded in next week:mrgreen:

ORY FTW
