so i have ordered the hedman headers and flowmaster three chamber suv muffler for my 92RRC. i climbed under the truck a minute ago just to see how difficult it would be to replace these parts. that is when i noticed the y-pipe coming from the stock manifold does not have cats and does not have O2 sensors. i search beyond the giant stock muffler at the center of my classic, and still....no O2 sensors anywhere.

did the uk models not come with cats or O2 sensors?? what is the result if there are no O2 sensors?

nobody has a clue? how do i tell if my rrc is equipped with an OBD II system?
i pinged EPA to ask about importing back to the US. they said it would be expensive and that i would have to install an OBD II system and correct the cats and missing O2 sensors before shipping. any ideas on that?

** update: flowmaster and hedman headers arrived today. both look very good. i dont see any noticeable issues with these headers. we shall see when the install goes down. i still need to figure out this missing O2 sensor BS. if they should be there, then i would like to knock it out while changing out the other exhaust parts.

Maybe not in all territories, but mine has them.

Did you fit the LPG system? If it is a close loop system they would have been fitted to control the LPG.

Sorry, had the year wrong. Mine is a 93 and doesn't have them, but by a UK site they appear to have changed in cars produced late 92 or MY93.

"The 14CUX has all the hardware to use Lambda probes to keep the fueling spot on to best suit the catalysts, and keep the emissions low. Any G33 produced pre August 1992 however was not fitted with the lambda probes or catalysts as it was not a legal requirement, and not running a catalyst can have a slight performance advantages, by not restricting the exhaust gas flow."

yeah, tracking on the differences with vs without cats. prob not going to see much in a small block V8. i just need to figure out how to get it to meet EPA standards so i can import this to the US when I leave here.

Why do you want to import it? They are very cheap to buy in the US.

uhhh.....because I will be here for like 2 years. im not going to dump all of the money in to this thing just to walk away from it. yes, they are cheap in the US.... but i already have over a grand in parts put on this one. why would i want to start over? and especially after i have figured out what makes this one tick. by the time i leave here, this thing will be in great shape. i am sure i can get my money back in selling it - but again, that requires starting over from the beginning when i get back.

I didn't - it was already fitted when I bought it. It's theoretically a closed loop system with single point injection, but it was a bit problematic so I had the electronically controlled mixer taken out and it now has a manual one. In theory this isn't ideal, but actually works just fine and I don't worry about it. The only 'problem' is that it won't pass an emissions inspection on LPG, so I just switch it to petrol for the test and it's fine.
