CAT soot build up

[fordfish]

If your set up with a tuner and dpf delete pipe, obviously the CAT starts to collect a buildup of soot, anybody know a good way to keep the build up to a minimum, since there is no more regen for cleaning?

Cut it off

He's right. No other way to build the heat up higher.

I concur. Removal is the only way to prevent build up.

If your worried about inspections or something, hollow it out and bolt it back on.

toss it, or get a full exhaust

Gutting it-Well, I don't want to replace it at whatever cost, when I trade. Is there that much to gain by removing it

The regen isn't for cleaning the cat. Nothing builds up in it. The 6.0 trucks have cats and no regens and nothing builds up. I would just leave it alone. You might gain a little taking it off but not enough to tell. It won't hurt anything to leave it on. I have a cat and a gutted dpf for 15000+ miles. No signs of cloging.
