Recently had mine installed with my 3" dp. The piece looked nicely constructed. Definitely recommended!

how is the fitment for this, will it bolt on directly in the stock location, or does it need to be adjusted somewhat?

Bolts directly.

Today i just emailed Randomtech regarding the flow of the particular cat...

This unit which belongs to the 7000 series and it has 3 inch inlet/outlet flows 617cfm...

I have to say that this is the HIGHEST flow number in cfm from all the cats i have ever seen...

It is even higher than the 597cfm that the Vibrant cat advertises on their website and vendor sites...

Now don't get confused. On their website Randomtech states that their 3 inch cat flows 502cfm, but this is the 9000 series and not the 7000, like the Evo cat, which is the race style unit...

This saturday i will put it on the car and see if it makes a difference from the Ultimate racing unit that i currently use...

What is the flow rating of the UR cat.?

i don't know an exact number, but usually the ceramic substrate cats flow in the high 300s maybe the low 400s cfm...

If this is the case then we are dealing with at least 200cfm more flow, which will definitely make more power.

Saturday i will install it in the place of the UR unit and make a baserun, before retune the car.

Last dynosheet was 344whp. I will put the Randomtech unit and piping kit (which i doubt it will influence the whp value, except maybe better response) and dyno it...

Yes, they will, but they aren't so cheap.

Randon Tech Cats are pretty nice. Just this week I switched out exhaust from a 3" TBE w/ Randon Tech Cat to a 3" TBE w/ Test Pipe. We only gained about 8-10hp through out the powerband on a Mustang Dyno. I might switch back since this new exhaust is so loud!

kouzman -- Would you please post where you bought the Random Tech cat? Also, is anyone running Meth or Alk. with a catalytic converter? (I have no idea if the additional fuel types would damage the cat.)...Thanks

Edgeracing.com has the best prices I've seen. Not sure if it was mentioned, but the Random Tech cat does not have a bung for the rear O2 sensor. I had to have one welded in at my local speedshop. If you've got a cat-back, no biggie though.

Also, you might want to have a look at the Perrin HFC. Its also a metal substrate cat. It is very similar in external appearance to the Random Tech unit. Kinda wondering if its not the same catalyst element. The nice things about the Perrin are that its a bit less expensive, the flanges are nicer, and it has an O2 bung.

I have the random cat also. It is nice. I have the older Buschur exhaust with the slip fit with the clamps. I hacked off the lip on one end of the cat, slid off the flange and put a new 3 in. clamp on it because there is a gap about 2 in. just large enough that it wasn't really possible to a flange on the mid pipe. I have a small leak where the bolts go in the clamp, but it is pretty minor. Just a heads up for people with the slip-fit Buschur exhaust.
