I am running the third cat delete, but I have a Pro-Cat hi flow third cat if you are interested.

ALTP makes a hi flow third cat too.

i don't think there's much gain from either of them.

Judging by the no. of views and the no. of replys it seems that there aren't many people here using hi-flow cats. The only reason why i will be going with one is because im planning on changing the j-pipe and the cat back so why leave the stock cat in place?

Any opinions on Magnaflow/CarsSound cats? I use to be into Mustangs (and still am, just needed something more ptractical) anyway a lot of people wtih these cars use Magnaflow cats with no issues and they are very affortable.

I was considering this one but have a question. I have found out the the stock cat is 3 way and the Random Tech. cats dont differentiate between 2 or 3 way cats. So does that realy matter when buy a universal cat?

I have one and it just seems like it makes the exhaust raspier with little or no gain at all.

if you swap the jpipe, and catback, you will be at 2.5"... it's almost mandatory to change out the cat for either a testpipe or a highflowing cat

the following choices are what you have
random tech thru excelerateperformance
magnaflow spuncat thru rv6-p.com
atlp hiflowing cat thru atlp.com
