Well, I'm running a 2.5" test pipe as it stands, but I'm addicted to 3" OD now with the 3" cattman, heh. This TP is for S13s and S14s, but is the same length and has welded flanges (as oppose to my current set up) and is SS. For $40, I figure I'd try it out. Wish it didn't have that 02 bung though. Anyone have any experience with this?

GET IT!! And weld a bung onto it..
Let us know how it turns out. I may go this route as well.

 

Are the flanges oriented properly though?

Lemme know if this works also

 

That's the one thing I'm worried about...guess we'll find out huh?

 

Or route #2... call Dallas @ WSP to fab up a 3" SS test pipe w welded on flanges...my guess $40-$50? They have a jig and it will fit perfectly!

 

I'm going to put my cat back on due to stupid cali emissions and the fact that if I get caught with no cat, I'm in deep sh*t.

 

I've been running a WSP metallic substrate cat for about 6 yrs now and it has welded on flanges and flows really well!

 

WSP as in warpspeed?

 

Yes! $165-$185 in 2003..IIRC

 

Cattman sells test pipes and a Fastcat as well

 

Have the Fastcat. Love it.

 

All metal. I'm sure you do.

 

I had 2 of those. Both fell apart within 2 weeks. Only mod I had at the time was a y-pipe...

 

If you had the Metallic substrate how did it fall apart it's all stainless inside and out? You sound like you had a ceramic Carsound and a air/fuel ratio problem or burning oil!

 

Oh yeah, CARSOUNDS I got from warpspeed. No air fuel problem though. Right after the 2nd failed I went to a dyno place just to check the afr before I wasted more money on a another cat. At idle and closed loop it was right on 14.5-14.8 and wot was right around 12 something. Also that motor never burned a drop of oil. Dallas said he had no clue why they failed...

 

Maybe a bad batch?

 

That's what I suspected after I was sure my car wasn't running rich...
