[Italian Stallion]

ive read online that in order to install it i need to get the small pipe for about $100? i was going to a shop today to get it installed but they dont do any pipe fabricating there and i didnt know of that piece untill about an hour ago. do i actually need it or not?

You need this...


If your exhaust looks like the one on the left.


Otherwise, no you should be good to go.

That's for 93-95 exhausts or something like that.

Adam you are correct. OBD1 you need it, OBD2 you do not

Unless of course, the car is a Kali emissions car, and a OBD1 car will have dual cat exhaust. Dem details

I thought 95 cali emissions cars were only on the 3.8's?

Incorrect.

Counting the cats is not proof of I or II on a 1995 LT1 F-body. If you have 2 cats on a 1995 LT1 F-body, it means it was equipped with California emissions. Single cat cars were normal Federal emissions equipped.

[sweetbmxrider]

Right I understand that but I am almost certain there aren't 95 lt1's that met cali emissions, only the 3.8's. Unless it was something late in the production year. I'll have to look into it.

I don't think its entirely to hard to have happened. I know for my truck there is subtle emissions differences mid model year between Kali and Federal emissions.

Having two cats would not mean it passes as an OBD2 car, but just stricter sniff test standards because Kali's tests supersede federal.

At least, thats my take on it.

[sweetbmxrider]

Again, I completely understand how emissions works and cali's regulations. I just was trying to research earlier and find where I thought I read that the only cali emissions fbodies in 1995 production year were 3.8's.

It wouldn't be a VIN thing cause that would entail it being OBD2 right? So it'd have to be a RPO code which you could prob find out and then research what it came equipped with.

Not exactly what I was looking for and doesn't completely clarify what we are saying with regards to lt1's but:

Wiki

1995

In 1995, base Camaros in California were equipped with the 3800 Series II engine for emissions compliance while base Camaros sold elsewhere retained the 3.4 L (207 cu in) engine. This would be the last year the 3.4 L (207 cu in) V6 engine would be available. For the LT1-powered Camaros, the often-problematic Opti-spark distributor was updated to include a vent to remove moisture from the unit. The cam drive system for the distributor was also changed, making "early" & "late" model cams and distributors non-interchangeable. 1995 was also the first year the fourth-generation Camaro had the option of painted side bars and mirrors. Traction control became available as an option on LT1 Camaros, but was installed on the base Camaros. Z28 rooftops, door handles, and mirrors, which were previously only available in black, now had the option to be painted the same as the body color.

1996

1996 saw minor mechanical revisions, as well as small power gains from the new OBD II-compliant engine controls. All base model Camaros were now equipped with the 3800 series II. V8 models still came with the 5.7 LT1 engine. The dual catalytic converters required by OBD-II resulted in lower restriction and a mild power boost to 285 hp (213 kW) and 325 lb·ft (441 N·m) of torque. Two option packages also returned: the RS (last seen in 1992), an appearance option for the V6 model, and the SS (last seen in 1972), a performance and appearance package for V8-powered cars. The SS cars were the highest factory performance Camaros offered at the time and included a functioning hood scoop and new five-spoke 17 in (43 cm) x 9 in (23 cm) wheels. The new wheel and tire package on the SS resulted in better handling and braking compared to the Z28. Convertible Super Sport cars however had 16 inch ZR1 style wheels. Also available this year for the V6 model was the Y87 package, which included an Auburn limited-slip differential, better tires, dual exhaust tips, 4-wheel disc brakes, a sportier steering ratio, and more aggressive gear ratio in the differential for automatic equipped cars. Available was a 4-speed automatic transmission or a 5-Speed (V6) or 6-speed (V8) manual transmission.

rpo YF5 dual cats was only on the 95 3.8 for california emissions after that dual cats were standard with obd2 following in 96

NB6 is the cali emissions RPO

Nope, see below.

Which meant dual cats on 95 LT1 A4 cars, not available on M6 cars.

Ah I see them on the 95 parts list 12555496 Right side 12553506 left side
