My right side cat has developed a rattle so needs to be replaced.

2 questions:

Can anyone confirm the correct part number :996-113-032-??

Is buying used an option (low risk)?

New and rebuilt units must be constructed of unobtanium given the pricing.

I want to keep the car stock so looking for an OEM replacement.

TIA

 

What year? For a '99, the right cat is 996-113-022-56 and the left cat is 996-113-021-56...

Pelican sells new aftermarket units for about $550, but they are not CARB approved (can't use in California and New York, which probably doesn't matter for a Texan, but worth mentioning just the same).

Used can be a viable option, but 996 cats are not very robust. If you go used, make sure they have a return/replacement policy if the new cat arrives DOA.

A third option (besides new and used) is rebuilding your stock cats; they cut open your existing cat and replace the catalyst. I believe some other 996 folks have done this and may be able to chime in with cost.

It may be worthwhile to check if the element just got dislodged (very common mode of failure) or it has truly "melted" and needs to be replaced. If the former you can ask a muffler shop to open it up and re-weld the insert. To inspect, just remove the cat and the post-cat sensor and peek through the O2 sensor hole and the open pipe end where it connects to the header.

 

Thanks for the quick replies.

Magnaflow sells CARB-legal cats for under $500 with a decent warranty

 

Call Nello @ Maxspeed Motorsports and get the 200 cel cats.

 

If you only change one cat, stay with the same as you are replacing. If you want to go after market, I would do both, not just one, and stay away from "DEC" cats; I bought those then threw them away because they kept throwing bad O2 sensor codes. I put on a used Porsche (matching) cat a year ago and it has been fine.

 

check with oaklahoma foreign for used parts

 

Again...

>>I did some research on a mfg number I found on some cats offered by various companies and found the company that makes them.

I know the name sounds shady, but I've used them on three different P- cars now and they are great.

Roughly $340.00 per side shipped.

 

Question on part numbers and compatibility. The part number of the defective cat is 996-113-032-06. While looking around for used or replacements I am seeing different part numbers - 996-113-032-02 or 03 (likely from an earlier 996 C2). Are these parts compatible?

TIA

 

Since you are in Tx , why not call Woody for used ones?

 

Woody?

 

Don't look at me.
