will the LT1 engine function correctly if I just delete all emissions in my ECM and not worry about installing the O2 sensors?

 

The LT1 and your ECM are mutually exclusive. The LT1 uses a specific PCM. It will run fine without the emissions components(AIR pump, EGR) with proper tuning. The O2s are needed for your engine to function at peak efficiency.

 

is there a way O2 sensors can be put into 3rd gen headers that has no O2 slots, or does anyone have information on that

 

Any competent exhaust shop can weld the fittings(bungs) into your exhaust. Make sure they are located at a point after all of the individual pipes merge together. This will ensure an accurate reading for the O2s.

 

ok, would I need a y-pipe for long-tube headers

 

If you are running it into a single exhaust system, yes. LT1s use two O2s, one on each side. I run my O2s in my collectors. You can buy them with the bungs already installed.

 

I c. Im going with the Hedman 68469 1 5/8 D-port long tubes and wanted that dual exhaust the kicks out of the side. and do you have a part # on that collectors with the bungs already installed

 

This is what I am using with my Hooker Super Comps. http://store.summitracing.com/partde...5&autoview=sku

 

does your car run fine with o2 sensors there, someone else said the o2 sensors should be before the reducers or y-pipe

 

I put the O2's in my hedman shorties directly into the collector before the y-pipe and haven't had a problem at all with them there.

 

just asking, what is/does the collector connect to

 

That's where the tubes of the headers come together and combine in an area where the y-pipe bolts to.

 

Jegs has 3 bolt header collectors with the o2 inserts in it for the 3" to 3". would I be able to use these with the long tube hedmans that has a 3" collector. that way I can just bolt them to the end of the headers , and they already have the O2 inserts, also If I wanted the both exhaust to come out infront the rear tire would I need a y-pipe

 

I decided to go with the Hedman shorty with a 3"to 3" collector that comes with the O2 sensor bungs. then I will get muffler shop to run me a custom dual exhaust. would I still need the y-pipe? by the way Im not running cats at all

 

There is a y-pipe that Hedman makes that will bolt right up to the headers, just buy two o2 bungs and have them welded in.

 

Would the headers work just with the collectors that already has the o2 bungs installed, and then just running it from there?

 

The shorties have standard ball flange on them and the flat header collectors won't work.

 

would u know what o2 bung size that would be

 

It's just a standard O2 bung, I think the ones I bought were 1 1/2, that's what size drill bit I used

 

would you know the part number for that y-pipe

 

17470

 

ok thanks. how hard is it to make the provisions for the o2 bungs because if its nothing to it, I rather do it myself than to get taxed by the muffler shops down here.

 

Drill a hole in the header collector just big enough for the bung to go into in a place to make it easy to take the O2s out if needed, and weld it up. I used a drill press to make sure I didn't screw up the hole or slip messing the headers up using a bi-metal hole saw.

 

i just bought an LT1 for my 91 camaro and im not exatly sure what i need for all the emissions, i live in california and im not too familiar with lt motors.
