Ok, here'* the exhuast. I need trim level and year, and I'd like to include the number and type of O2 sensor(*) if possible, also if there is a resonator.

Example:

1995 SSEi, dual pre-heated O2 sensors, resonator, single in/dual out Muffler.

Did I even get that one right? You get the picture. Lets have it guys! Fun stuff...toys, options, etc will be next!

I'll start with the 93 SSE and SSEi.....

Single non-preheated O2 sensor, no resonator, single in/dual out muffler.
Pretty sure 92 is the same, 94 similar, but used a single preheated O2 and no resonator?

'95 SSEi, 2 O2 sensors (heated), single 2 1/4 B pipe, resonator, dual exhaust outlets.

92 SE 3800 NA, non-heated single O2 sensor with single exhaust into muffler & dual out to passenger side only

Al, is that dual out on the passenger side stock? If it is, is it the same for the following years on the SE?

Yes it'* still stock, except for the CAT which I've removed. BTW: No resonator either on the stock system! The SSE/SSEi for 92 has dual out too but one pipe goes to L/Rear & other goes to R/Rear. The SE outlets are on the passenger side of the muffler while, the SSE/SSEi'* outlets are on either side of the muffler!

Gotcha. SeriesII SE'* stay the same from 95 on?

Don't quote you? HAHAHAHAHA Just did!

You got me on the converters. Maybe the Rat can help there, too. I know what TWC is, but what the hell is ORC? Sounds good on the SE exhaust, but did the 95SSEi have headers still, since it was still SeriesI? Stands to reason. Yes, I have headers....and they should have been from 92-94 SE and SSE, 92-95 SSEi. Right?

ALL 3800'* came with GM Factory Headers! GM call them manifolds though in their database so to **** up us partsmen & keep us on our toes! Speaking of how really hard it is to look stuff on the GM Database see if you guys would get this! CAPSULE = Sealed Beam Headlight
Module, Sensor & Switch sometimes interchange
Fuel Pumps are in 2 groups with 2 different P/N'*!
Medium Duty Truck Groups can be different than Light Duty Trucks/Cars!
BTW: GROUPS are the different catagories that parts are grouped in.
Group 00 = Engine, Clutch
01 = Oil, Cooling System, Grill
02 = Chassis Wiring, Lamps
03 = Fuel, Exhaust, Carburation
04 = Trans, Brakes
05 = Brakes, Rear Axle, Propeller Shaft, Wheels
06 = Front Suspension, Steering
07 = Frame, Springs, Shocks, Bumpers
08 = Front End Sheet Metal, Heater
09 = Body Mounting, Air Conditioning, Instrument Cluster
10 = Doors, Regulators, Windshield, Wiper, Washer
11 = Rear Glass, Seat Parts, Adjuster
12 = Body Moldings, Sheet Metal
13 = Body Wiring, Vinyl Top Trim
14 = Interior Trim, Seat Belts
15 = Rear Seat Trim, Carpets, Yardage
16 = Cab And Body Parts
17 = Load Carrier Parts
21 = Accessories (Production & Non Production)

I don't want to know all that ****! That'* what we have YOU for
