Who makes a functional cat converter for 2.5" collectors? I'll probably end up having custom 2.5" exhaust pipe, so all I need now is just a cat... Preferrably with pre-welded flanges and 02 bung. Vehicle is 00 Si.

 

I bought a 3" random tech, and had it welded in with flanges. Works great. Cost about $150 for the cat.

 

Any place online or any dealers on honda-tech? That's a decent price. And do you know if you can get an 02 bung with it too?

 

I didn't need a 02 bung for mine, my header has the 02 sensor in it. PM me, and I'll get you pricing.

 

wouldnt 3" be too much if for an exhaust if your not turbo?

 

Doesn't seem to bother my car.

JDM 4-1 w/ 2.5" collector --> Random 3" cat --> Apex'i N1 2.385" exhaust.

No problems here.
