Is anyone aware of a cross reference for a cat converter with 2.25 inlet and outlet, 3 bolt flanges and 10 inch length (standard Civic/Integra/Accord fitment)? I tried looking at specs the ITR, it's only 2. I tried v6 Accord, even looked at cats for Supras etc.

I'm doing an ITR swap on my daily and want to keep everything 2.25 consistent. I don't want to be dependent on an exhaust shop to weld one up.

Thanks

 

Any good muffler shop should be able to make what you need. 94

 

Thank you, I'm aware, but I really prefer something off the shelf that I can bolt up in the driveway in the middle of the night. And also be able to replace it the same way should the need arise.
I'd be surprised if someone doesn't know of one after all these years.

 

I would be surprised if there was an adapter like that, but as I said any good muffler shop should be able to make it for you and you could install it.

Question, where are yo trying to adapt to/from, from the cat to the exhaust pipe or from the down pipe to the cat?
Got any pix? 94

 

I'm not adapting anything. The ITR downpipe is 2.25inch, my exhaust is 2.25 inch. I'm looking for an Integra/Civic cat but larger 2.25 inch inlets and outlets. Biggest I can find is 2inch.

I'm looking for a catalytic converter. 2.25 inch inlet/out, roughly 10 inches long.

 

Have you checked with... Catalytic Converters that is what I have on my 94 RS with a full 2,25" SS ceramic coated H&S exhaust, not sure how long the cat is but it was ordered to fit the system, far as I know they have anything you need. 94

 

I was looking for exactly what you describe and couldn't find anything. I ended up with a 14" OAL universal Eastern converter and chopped the flanges off of a cheap test pipe. The lengths match perfectly so it wasn't too bad of a job. Just FYI, I wanted a bolt-on solution also.

 

I ended up getting an NSX cat. It's the right diameter and length, but doesn't come with flanges. I'm going to have the exhaust shop put the flanges on ahead of time so I can assemble the exhaust in my driveway.
