2000 4 cylinder Exhaust Help!

So I went to the exhaust shop today and when I asked to get my cadalitic converter cut off he said sure man. We raise the truck up get the saw and tubing ready to reconnect to my glasspack. And ....He looked and said he cannot because ther is and o2 sensor it will have nowhere to go after I cut..And if it does not read the flow coming out it will screw up my computer stuff in my truck....HELP! there has to be another way. Can I not cut an exact spot in the new tubing to put it in then weld?

An before any of you twats start saying YOU CANT CUT YOUR CAT OFF THATS ILLEGAL BLAH BLAH BLAH THATS FEDERAL I KNOW THE LAWS!....just dont reply. there is no checks for cats here in Mississippi anywhere. so save your breath.

Thanks, Selby

 

From wat i have seen cutting off the cat and just plugging in the 02 will f**k shit up... my cousin did it to his dakota.... sounded good but he got like 6 mpg and all his sensors got all out of wack............

 

Like I said before, dont do it. You're not gonna get substantial gains in power and frankly, its gonna sound like shit. The only way to get around throwing a code, is adding a O2 simulator.

 

If i was going to install exhaust on a 4 banger I would go custom from the cat back. It will save alot of headaches from throwing codes and screwed up sensors.

 

This is Trace Mines already cut off i don't know how they did it though.
