hi flow cats ???

A little OT,
Anyone besides pacesetter make a Y pipe to replace the factory Y in a 2001 fed emmissions?
I had heard the pacesetter Y pipe isn't very good. My cat is a magnaflow 3" si/so.
Wondering myself how much I might be losing to that stock Y with my current configuration.

Cut pipe on muff side of the cat, remove the o2 sensor.
Bash the crap out of the cats insides(long bar)
Move exh pipe off to the side & start the truck & give it some revs to blow out the debris.
After welding it back up you may get a CEL.
In some cases (mine) I was able to just reset the pcm (disconnect neg battery/key on 10sec) & the cel/limp mode went away.
Guys with newer model years may have to get an o2 sim (maybe detected by inspection) or use the plug non fouler trick.
That may also be detected visually though.
3rd way is a bit tricky. Have to place a mark on the o2 sensor that shows where the IN side of the cat is.
Pull the sensor & weld a tiny V shaped piece of metal that will shield the incoming gases from contacting the sensor as much but not interfer with reinstalling the sensor.
Kind of like this if it makes sense

Booming the canyon walls to knock loose the stuff that's coming down anyway, huh?

lol! What can I say? These trucks sound bitchen. It's all I can do to not just go sit in it in the drive way and rev it in neutral all day. Lucky for the neighbors I usually drive it on the weekends. Besides I think they like the sound of revving bikes better...

In Texas, if you live in a high population county, you have emissions testing, but I THINK it's just visual,(ie, do you have what looks like a cat and O2 sensors.)
If it's a rural county or a farm or commercial vehicle, there is no emissions inspection.
They'll get you for a blown light bulb in the rear bumper before the cat, IMO.
