What length cat should I get. I see there are 18", 13", and so on? What is the difference between 2-way and 3-way, I see this for a few listed?
These are just a few questions I had before getting one. lol smile.gif

 

What is this going on? If you need one to replace the stocker, I have my 2nd one. If you need one to go into an aftermarket system, then get any size and have a shop weld it in.

 

well we are kinda on the subject, anyone know a cheap place to buy the o2 simulator's to get rid of the check engine light? im straight piped, and have been for about 2 months, and last night it decided to throw the o2 code, so it must have finally realized there was no cat.

 

No ,I'm looking for an aftermarket one. I'm getting my exhaust done catback. I was wondering if it made a difference in the size ( length ) of the aftermarket cat that is installed? And was wondering what the difference is between 2-way and 3-way? Is one better than the other?

 

No offense.. but for the one or two HP that a cat would have absorbed.. why did you go straight piped? I do not know about you, but I happen to like breathing the cleanest possible air I can. On a race car that might see a thousand miles a year, I can understand, but not on a street car.
