Good to know, I really like aFe's products. How long have you had them on?

So here's the info to date. On a stock car with just a tune, they made the same increase as cat delete pipes, 50whp. They are spiral cats, bonded to the shell so the can't/won't come apart. I've got no dog in this fight, just passing along info to those that may be looking for an alternative to catless and the smell and yet still have all the benefits of being catless. Oh, and I would consider anything over 700whp on a heartbreaker Mustang dyno "high horsepower"... Dynojet is for those that just want a sheet to wave around. 馃ぃ
There really isn't that much difference between a Mustang and Dynojet dyno, some for sure but certainly not a lot. A lot of it comes down to how the dyno is calibrated and the operator.

I have not put many miles on them yet, I was going to go with the JBA's but I did not like the unwelded flanges. I also recall hearing about one of those failing and taking out a piston.

I'm wondering if the new cats that FCA put on my Cat for the V86 recall are higher flowing? The car makes more burble noise when off the fuel and down shifting. I like that noise, but not the noise it makes at shut down. Or is the burble something else they phucked up?

Cats are the same, not higher flowing. Bubble and popping is usually a sign of unburnt fuel in the exhaust.

"High flow cats also offer better torque gains over catless."

Do you have proof of this?

I had the opposite experience, when i did this test...

Will these throw a CEL if not tuned?

Then it sounds like something else they Phucked up with their reflash.
Funny you say that, I thought I read someone else on here said they noticed their car was popping more after the most recent flash. I don't know where that post is now.

Now I need to listen to mine. I usually have my music going and enjoying the ride, but now all I try to do is listen for more mess.

Dynojet averages 12-15% higher than a Mustang.. that is a huge difference when you're in the 800+hp range and want to boast dyno sheets.

Not nearly that high and again it depends on how the dyno is setup. I've dyno'd on both.

Come next week, I will be testing them with water/meth, oversize snout and 105mm throttle body for a few weeks but they are good to go . Tunetime in Lakewood NJ are the guys to call for all the info on them.

It's possible that the latest flash is pumping a bit of extra fuel through on off throttle in an effort to cool the cats.

Gains on the prototype oversize snout and throttle body so far. We got the snout weeks ago but were unable to dyno anything other than stock pulley size. Manufacturer only supplied stock pulley and, because the pulley system has changed, we had to wait for them to engineer smaller pulleys. Gains so far, with snout and 100mm throttle body are 40 whp (mustang) on a 2.85. Today we'll test 105mm throttle and turn the meth injection back on. Should be around 90whp gain. Still running the prototype high flow cats with no issues.

The high flow cats have stood up to everything. At $1500 they're not cheap but, when you consider you have to use Kooks headers with their cats it's a steal. Kooks setup is expensive and about 7 hours to install. These take about 30 minutes to install and have a wider diameter cat.
