Secondary cat delete.

I made an appointment to remove my secondary cats.. I have already removed the resonators .. Should I be worried? Does anyone have this mod done? And will I get a \"CEL\"? Just wondering before I do
This.. ? Thanks guys

I was runnin sec cat delete way before getting a tube and never had any issues,the O2 sensors go before and after the primary cats, so taking out the sec cats wont throw CEL.

Ok ok i see.. that's what I've been told.. Just wanted to double check before I go ahead and do so.. So I'm good to do this? How about inspection and what not will I still pass or will I have to save the cat and put it back on down the road?

Egad people.

Nothing you do after the primary cats and secondary 02 sensors is going to cause a CEL. Neither will it make much power.

No CEL, Sosi has an X pipe that gets rid of 2nd cats and resonators. Much easier to revert back to stock then hacking the stock xpipe apart.

no CEL for anything after the primaries. and +1 for just replacing instead of hacking.

Anytime you leave primary cats you have to cut exhaust

Depends how the inspection is done in your state,in some states they just plug the a cable the OBD II port and it scans the car and check for errors and emission errors,in other states the still plug it in and do a sniff test .if the sniff test is performed................you are not going to pass !

All secondary cat deletes require you to cut the stock exhaust, but you can always use the same clamps to put the OEM x-pipe back on. If you gut your stock exhaust, though... there's no going back. And finding a used OEM x-pipe may not be easy depending on where you live.

Exactly what I'm saying, you will have to cut your exhaust to keep primaries. You can simply replace your secondaries with an inexpensive piece of straight pipe and go back to OEM by the same process you mention. Although I found it very easy to pick up an OEM X-pipe.

In most states, it's illegal to sell a car with any emissions equipment removed (even secondary cats). However, the chances of anyone finding out or even caring is slim to none
