I have a random tech cat installed on my '95 g20, I used part #822230 and it fits fine. I think it's the same as #822231 except ..30 has an o2 sensor bung. I don't remember the measurements on it though. Did you measure inside or outside diameter?TeqP said:I was wondering if anyone has purchased a random technology catalytic converter?
I was planning on buying one, but I am not sure about the model #.
I thought the sentra 2.0L Model #822231 would fit, but when I called random tech, they said that the in/out lets are 2.25". My stock cat in/out lets are 2.5" (i used a digital mic to measure).
If anyone has the correct part # for a cat that would fit my 93.5 G20, I would appreciate it.
Here are some links about exhaust on SR20's that might be helpful.TeqP said:I measured the inside diameter and it was 2.5" on my stock cat.
Would there be a problem if I used the smaller diameter and my original was 2.5"?
The 2.5" model they recommended is for a Maxima
How do you like the new cat?
