as title states, our accord needs a new cat. obviously an oem honda one is really expensive and want to go save a bit of money with going aftermarket.
here is the description to one I am thinking of getting from rockauto. Should work find without throwing a cel right?

BOSAL Part # 0993672 Direct Fit; Not Legal For Sale in the State of California Direct Fit
Sedan, Coupe; Federal Emissions; O2 Sensor in Center; Standard Load

 

I can't verify the proper part #, but Bosal is OK stuff. They're not a junk fly-by-night company.

 

well I just noticed another bosal cat from rockauto wth the same description.
one is $135 and one is $340. should i opt for the pricier one since its a ULEV engine?

 

ULEV engine never came with manual trans. Has the engine been swapped? If so, is it actually operating as a ULEV? What ECU is being used?

If it's really the ULEV engine, you'll have to be careful about getting the proper cat. I don't know if the price difference is LEV vs. ULEV or something else.

 

I say its a ULEV because the valve cover says ULEV-Vtec on it. dont know if that is a silly assumption to make or not.

We had the car since new so no engine swapping and I dont know how to check the ECU in the accord.

found this, so looks like they did put ULEV in MT accords in 01

we actually have two 01 accords now, one EX and one LX and both have the same valve cover saying ULEV.

 

You're right, I guess that's different from year to year. I remember looking up for someone else, but it might have been 1999 & I assumed it was the same for all 98-02.

I just looked up, & it seems to be different converter according to Honda's part number. DX, LX, EX all have the same converter but the EX-ULEV shows a different one. So when you find a converter, be sure the applications list makes a difference between the converter for a ULEV engine vs. a non-ULEV engine.

I don't actually know WHAT the difference is.

 

I'd like to know how you made out. The original in my '98 was replaced with an inexpensive 3rd party which lasted about 3 years. I was faced with replacing it again, so I opted to go the OEM/Honda route, which probably added $300, but I'm hoping it never needs to be repaired again.

 

I ended up going with that bosal that I had mentioned. cost me $300 shipped off amazon. got it on the car, everything fit no problem and no CEL from it. car is running good and quiet. Still have a CEL from the egr but at least its not from the cat!

 

There's a lot of cheap aftermarket "cats" that are little more than a test-pipe. Gotta be careful what you buy. But like I said, Bosal is a major supplier of exhaust & catalyst stuff.
