With RMT, cats are definitely an unnecessary risk to the turbo, though, no question there.

honestly if anyone knows a thing or two it's red

You know, I was wondering the same thing, but that topic has been beat to death on this board so I just left it.

Honestly if you know anything about cars or hell even have common sense, cats getting sucked into the engine can't physically happen.

Right. I'm really surprised it didn't damage my turbo when I burnt them up and when I say burnt them up I mean it melted the screen guard inside the cat. So where that sh*t end up at is beyond me. Hopefully it got caught up on the out flow side of the cat.

Removing them just releases the air flow 1000%.....and the noise

The car is now more or less straight piped.

I was just sayin, Red knows his stuff, for the people in question

Just things I heard about having cats on for turbo cars.

I can see it getting sucked into the turbo on a RMT kit but I'm pretty sure it's gonna stop there and not cycle back through the innercooler then into the engine. Maybe it's the "magic bullet" theory for car guys.

I've actually seen it happen, although almost exclusively on cars with pre-cats that are right on the end of the headers, and only when initiated by core failure

The turbine and the compressor aren't using the same air. I can't imagine chunks of cat hopping between housings

You can look at a picture of a turbo and pretty quickly figure out that core chunks aren't going to wind up in the intake.

Huh? You've seen it happen ? How ? I don't understand how they could get in the engine

The short explanation is that there is some overlap between intake & exhaust valves opening. There is vacuum in the cylinder, and backwards airflow (backflow) is pretty common, generally sucking some small amount of exhaust gas back into the cylinder. In cases where a cat (again, generally a pre-cat because of their proximity to the exhaust ports) has broken down, you have
A) loose pieces of honeycomb floating around
B) significant increases in backflow

and it becomes technically possible for cat material to flow back into the engine.

When you say pre cat, you mean cat before the header ?

Yeah, I understand the two sides of a turbo...I was meaning in stopping inside the turbo and not going anywhere else....poor attempt at being a smart asz

But it flowing backwards??? If this is a somewhat or even a rare thing to happen I would hope that they would of already solved this kind of issue from ever happening.....At the same time I'm not a mechanic

Do not buy from STS turbo they take months to finish their bolt on kits on any car it took them 6 months to put on my turbo kit on my car and they wanted full payment within 2 weeks i waited half a year for their basic kit!!! And they would not give me discount is costed over $14k every week after the first month i constantly contacted them and they kept saying the car will be done next week they kept saying for 6 months!!! WTF these guys are lazy,slow and dont give a sh!t about their customers. I want to know can i sue them for having my car for so long and charging me more then their estimation on the price and telling me it would be done in 3 weeks and they kept telling me it would be done the next week for 6 months.

im sorry guys my grammar sucks im just really mad at them.
