Just wondering what the dimensions of the secondary cat, the one directly off the y-pipe, were. I'm need to replace mine as it's getting clogged and i'm loosing hp. I saw a few universal ones by eastern catalytic for real cheap but i'm not sure what dimensions my converter is. Thanks

 

it's either 12" or 13" long, not sure on the diameter

 

I think its 2.5" and 12" long but don't qoute me on it

 

OK, thanks. for those who have replaced this cat, what kind did they replace it with. A lot of reviews say that the cheaper the converter the crappier it is. I want something that will get the job done for not an arm and a leg. if it happens to add hp all the better..btw I would also enjoy passing the emissions tests.

 

Here is one option on Stillen's website:

I haven't really seen too many other options for catalytic converters. It's pretty expensive though and I've heard that it makes little to no difference as far as horsepower goes, despite its "Super High Flow" name. Might make your exhaust sound a little different though...

I think Cattman also carries catalytic converters, though I don't see any on his group deal thread. You may want to give him call though...

Contact Cattman or Warpspeed,
I have purchased 1 metallic substrate from Warpspeed for my "03" and a ceramic for my "90" both flanged and both a perfect fit! Highly recommend it; they start at $100(ceramic), $185(metallic)

 

how is the ceramic one? Is it worth it to just pay the extra money for metallic?
