True duals????

The back O2 sensors don't do anything? Then why are they there?

Did anyone else feel like jamesbtri had his pinky twitching over the cAPS lock while typing that?

Depends on which shop you go to. My local auto mechanic recommended ditching the cat on my 92 F150 to run true duals with glasspacks and I had no problems with anything. My 97 chevy has true duals with no mufflers at all but it still has the cats. I figured since it already had two cats, why get rid of them, you can have dual exhaust and still be legal. Talking with buddies of mine no one has had any problems telling exhaust shops what they want and getting it.

Also if the SES light bugs ya, you can get this little gizmo thatplugs into the rear O2 sensor harness and fools the puter into thinking everything is hunky dorie

I agree, I have the O2 sims on my truck and no SES light...

I have a 98 K-1500 and I dualed it out over a year ago. I didn't replace the cats as there are two cats on two seperate pipes. From the junction after the cast I had the muffler shop weld on two seperate Flowmaster Delta-40 mufflers and exited the exhaust pipes with tips behind the truck. It sounds very good and I highly recommend the Flowmaster mufflers. Good luck and enjoy.

The rear o2 sensors are only there to tell the pc that your cats are there . As far as them tell the computer to do anything like change the air fuel mixture they dont . That is the front 2 sensors job ! So if you where to remove the cats leaving the front 02 sensors in place the truck will still run just fine. However the ses will turn on , but if you can live with it will do no harm to the motor or as stated below in another post you can buy 02 simulators to keep the ses light off !




Not look to stir shieatttt just stating the facts!
