Catalytic converter issues

[B229218]

I have a Whipple stage one has anybody had any blowout issues with their catalytic converters yet? I live in California so long tubes and aftermarket converters are out. Has anybody found out what the new supercharged. Dark horse is running for converters? I wonder if those will bolt in our cars.

Yes I've experience cat failure. Whipple update the tune in the last couple months that might address this. My filename has stagefp_v2sk_rr3a in it. My cats failed within 4k kms of installing the supercharger. I always put 93 in it.

I think the mustang SC has the 5.2L motor.

I saw a Fluid Motor Union video the other day where he spliced some GT500 cats onto a S550. This is a carb grey area because the cats have 51 state approval, but not on a S650. I'm not sure if the Dark Horse SC cats will bolt right up.

You have factory warranty so if you do melt the cats Ford will replace them, if you stay on the stock tune.

What happens if you just remove the catalytic converter?

They kick you out of California.

there ave been several cases from people on this board who have had the catalytic converters melt ( the inside honeycomb overheats and turns into a blob)

A couple of cases were people pushing the car hard for a long period of time, others had put more boost in than the number Ford achieved with the stock Ford Performance pulleys.

Frankly the Ford tune is as much as you can safely boost the car and even the it does not like running high or full boost for extended periods of time. You can push it past the Ford limits but you are playing with the possibility of catastrophic and expensive failures without beefing things up.

Ha. I'm in Florida and know a guy with a Super Snake who added headers, then removed the Xbox and cat at the same time & thus had a straight pipe to the muffler.

I'm sure his neighbours love him.

Yeah California is a bit draconian with their emissions sniffer boxes on roadways being able to detect and flag vehicles that aren't emissions compliant. My province lets you do whatever you want and the federal government doesn't bother enforcing anything. It sucks to see commercial / long haul trucks spewing tons of unburnt diesel into the air though.

Also I don't think they kick you out, you just can't register the vehicle plus fines fines fines and more fines. However after watching the movie Speed, I'm sure California has a spectacular public transit system that meets everyones needs in a timely fashion and in some ways is much better than owning a vehicle. Along with walkable communities that make car ownership irrelevant.
