hey guys what is the best way to gut the cat on my truck

 

Buy a high flow

 

i cut one of the inlet pipes off and marked it then i stuck a crow bar in the hole and beat what was left of the honny comb into small enough pices that i could shake them out and then i welded the pipe back on where i marked it then smoothed the weld and if you look right now you cant tell it's been touched.

 

im also thinking about doing this and i was told you can just take off the cat back... and then get a pointed bar and hammer out the cat.... and hten turn on the truck and rev it a little to get the honey comb type deal out... after a little of that just bolt back up

 

Pretty much how you do it...right now mine is rattling pretty bad, and I plan on doing this today, if I can get my catback loose enough to pull aside to punch the cat out

 

I have had the cat on my 1999 360 gutted and I did not like the tinny hollow sound that came from it, so I got it removed and the O2 sensors put back on and now it runs and sounds alot better. I have had it out for about 6000 kms and it still runs fine and the check engine light never came on

 

by gutting the cat/ romoving the cat.. will you notice a drop in fuel millage... like get less mpg.... or is that only if you take the sensor out.... also if you take the cat off and replace it with a 2 1/2' tubing how do you put the censor back in.... and if you dont will that make a diffence in anything

 

youll have to sim the 02... not exactly legal in most states ... especially emission sensative states like cali and ny... where vehicle inspection is like brain surgery

 

Glad I live in Michigan and they don't really give a crap what you do Do are suppose to have a cat though, but there are no inspections ever.

 

Gutted mine in my 97 and regreted it ,lost all low end power.
