    Time is the true test. I have gone this route of having cats recored with metal catalysts, and they worked for a few thousand miles, then started throwing "low catalyst efficiency" codes, which some aftermarket metallic core cats do as well. I am back to factory catalysts. If you guys didn't know, Ferrari used metallic cored cats in 1999 production cars. I found one on Ebay (new) and bought it...you could tell immediately the difference in the matrix from the original ceramic ones. These were the ones Ferrari was offering on a "special" a few years ago for $3500 installed for the pair at FNA dealers. The guy I bought from said he only needed one, and kept the other in storage....and later sold to me.

    No CEL's but I put my code reader on today and it showed a pending P1451.code. ill have to check some more to see what is causing it.

    OK. I finally found the time to take my car in for a smog check with the Fabspeed re-cored OME Cats. The word from the technician was that everything was reading really clean and based on the emissions, the car would easily pass in California. California has the most stringent emission requirements of any state and I was told that a pass from a California station is acceptable in all 50 states. No comment on the re-core of the Cats either.

    Below are the emission readings from one pipe at 1,000+/- rpm and both pipes at 2,500 rpm.

    If you want to have original looking Cats for either Concorso or State requirements with increased performance this looks to be a good way to go.

    Frankenstein welds at best!!! 2nd set is much better and still period correct IMO.

    In fairness to Fabspeed, mine was the test case. Even with that, for some reason I have two different Cats that they had to work with. The one with the clean weld had a heat shield around it which looks to have been easier to cut off and weld back together. The other one (right side) has no heat shield and has the numbers stamped right on the exterior wall of the Cat. I haven't heard back from anyone if this is a "normal" configuration.

    As for the welds, I could have used my grinder on them but I didn't really care. Its not noticeable when on the car. My car received a Gold at an FCA Concourso a week ago and no dings for the Cats. (Other ticky-tack dings though)

    HI Guys

    It is Joe Fabiani at Fabspeed Motorsport USA. I wanted to let you all know that the Fabspeed engineering team are actively working on Ferrari OEM catalytic converter rebuilding/ recoring services here at Fabspeed Motorsport USA. For concours and or "looking stock" this is a possible quality option.

    Factory Ferrari catalytic converters are very restrictive and often ceramic material (700+ CPSI and the bricks crack, implode and fail. On USA 360 and 430 cars every single North American car has 6 catalytic converters factory installed and besides the catalytic converter failing over time............there is a TON of sportscar sound and power that immediately liberated with HJS highflow 200 cell catalytic converters. Its not marketing BS its really true. These engines simply want to breathe.

    FYI>
    Currently, Fabspeed has assembly Jigs & welding fixtures and has been manufacturing High performance HJS racing catalytic converters and or catbypass pipes/ straight pipes for these Ferrari OBD1 and OBD2 models: 328, 348, TR, 355, 360 & Challenge, 430 & Scuderia, 458, California, and F12 Berlinetta .

    Each and every Ferrari application requires a certain part# HJS Tri-metallic catalytic converters sized for Ferrari model application to maximize power, fit in the stock location, scub the spent exhaust gas while keep off a CEL light (1996 cars are OBD2) and be extremely durable.

    For example- I consulted with HJS Germany and they specifically recommended a new massive HJS catalytic converters that should arrive any day by FEDEX because the F12 makes 730+HP stock. Other companies could have simply installed a Porsche Twin Turbo or domestic Mustang/Camaro or Corvette catalytic converter..............but the cars power and exhaust flow would have been negatively affected given flow modeling.

    I am NOT making any of this up. Some of these aftermarket companies serving Porsche Ferrari, Lamborghini, Maserati, and other exotic cars are simply Slapping on Chevy Cobalt style cats, Chinese catalytic converters or undersized NO name catalytic converters are Charging Big Bucks for parts that are polished but lose power and often have cores that unravel/unwind/collapse and have very little precious metal wash coating. Platinum, Palladium and Rhodium.

    Ferrari, Lamborghini, and McLaren are using EMITEC brand catalytic converters that they buy in 700 cells per square inch and have wash coated. HJS Germany buys EMITEC tri-metallic cores in 200 CPSI that vastly outflow the OEM restrive cores and heavily loads the metal matrix.

    Fabspeed Motorsport USA buys these highflow sports racing catalytic converters in bulk and stamps out endcones (for example>>reducing cones to take a 4.5" round catalytic converter down to a 60mm tube). We then orbital TIG weld these cores and then weld them onto our CNC mandrel bent pipes while adding EGT probes, Oxygen sensor ports and flanges as dictated by the build manual as dictated by the specific car model.

    Going forward we can easily cut open remove catalytic converter cores and weld in properly sized HJS high flow cores and REMOVE stupid flow directors (1980s ignorance that hurts flow) and steamline exhaust pathways. If the gaps are big and or the Ferrari catalytic converter shells are beat up or failing a quality OEM style MIG weld will close up the gaps and make a strong weld. Each and every single product Ferrari, Lamborghini, Bentley, McLaren factory OEM exhaust systems is MIG welded. There is nothing wrong with a MIG weld and 95% of the time the part is completely hidden in the chassis of the car.

    Fabspeed has many sizes (O.D. outside diameter and length ) of HJS German tri-metallic catalytic converters in stock for these cars. HJS Germany is worlds preeminent catalytic converter supplier and Fabspeed Motorsport is HJS Germany's #2 volume buyer of their catalytic converters.

    Feel free to cruise by our facility and we will show you everything. You are all cordially invited. On my little 2003 360 spider 6 speed I have Fabspeed headers (eliminated the restrictive lousy pre-cat in the factory USA 360 header) and a pair of HJS 200 cell HD Euro level 5 catalytic converters going into either my TUBI muffler or the Fabspeed Maxflo 360 muffler. She really rips and sounds great!

    Hyperflows finally gave up the ghost, being in California, never liked them anyway as the chrome failed the visual more often than not. A fellow fchat member sold me a pair of hollowed out OEM units several years ago, Ted at Fabspeed had them done and back to the shop in no time. Not only did the car pass smog, it no longer triggers an automatic fail on visual…hooray.

    Good luck. My experience with recored OEM housings was not so great. They work for a time...perhaps a year or so...then the dreaded "low catalyst efficiency" code. After a couple tries I gave up and found some new old stock OEM Ansa 1999 metallic catalysts.
