not me. that was swoope, I poo-poo'd it when he first got, but it's lasted him well
my latest cat has several times more flow area, more flow per cpi, premium catalyst materials, and is rated for 400+ BHP, but the negative is it cost 6x more than the Davesport unit

Nemesis: what pipe are you welding it into?
I've considered cutting up my RP High Flow and possibly having a davesport Cat welded into it.

In a S2 the O2 bung is in the CAT itself, not the midpipe. It has front O2 sensor at the end of the header and a rear O2 in the CAT itself. No idea if you can move it outside the CAT without a CEL though. I'm still running stock but I do remember the layout from my header install.

The OE converter has two catalyst bricks with a space between them and the O2 sensor reads the exhaust gas in this space. The aftermarket cat is a single catalyst brick. Putting a bung after it is the same as the OE setup as far as the rear O2 sensor is concerned, it's just that there isn't a second catalyst brick after it takes the exhaust reading.

Let me check again tonight, because that does sound odd. Jedi - I will be working on a Racing Beat straight race midpipe.

very nice Nemesis: can't wait to hear what you think of this cat.
Where's swoope been? Maybe I'll harass him for some more info on these things. While I like my RP cat, I am on my second one and am not sure how much longer this one will last. Some people have great luck with them, others don't.
Al: if you get around to doing this, let me know what the pipe diamater is, would ya? Or if I beat you to it, I'll send the info to you.

Swoope did something different with his setup. He put the cat to the rear of the midpipe in hopes that the exhaust gas would cool slightly and possibly lengthen the life of the cat. I'm not sure that is necessary with this cat. It will also require an extension cable to reach the new location for the last O2 sensor.

I have the blown rp cat and hipo cat sitting around. I just haven't done anything with it yet.

the first one did not.. had to send it back, but they did get it right..
