Anything flex is never a good idea. As for the cats, numerous guys with Roush stage 2 blowers are killing them with a few wide open blasts at the track.
It's an option. I thought possibly some aftermarket innovator would have come up with something
Might be the only solution
Flex joints aren’t so bad. It’s how they deal with thermal expansion. The gt500 has one on each side.
I didn’t say cats aren’t failing. Ive failed 3 myself. But none of them were melted is my point.
Back then you made do with what you had. T squares and machines driven with leather belts. Now with computer aided design, FMEA, simulators and computer aided manufacturing I would think they can do better. Except when accountants get involved.
The DEMON doesn't.. and it's the same manufacture type cat. Factory knows how to tune with cats intact. Most aftermarket tuners do not.
Maybe Ford doesn't do a good job with their engine strategies. I know a few stock 2013 GT500s that burned up some cats. They appear the same as the ones that are on the 550. Roush works with Ford to do their tunes for the stage two set up. Several of those have burned up cats.
Are the gt500 cats better? I would assume they are. Are they a better alternative?
Yes I have a pair on my 2018 now. But they don’t fit super easily. And they have flex joints.
