It's interesting to see the different exhaust systems these cars came with. The one I just purchased has a full dual exhaust system with dual cats and mufflers leading into chrome Y-pipes when asked the original owner about it she was adamant that the exhaust was never replaced. Another one I saw had a transverse muffler mounted between the rear end and gas tank

The Esprits & base 301 Formulas & TransAms in 1980 came with pellet style cat convertor & a single pipe to the cross flow muffler. The W72 optioned 301 & the LU8 Turbo equipped cars had a different pellet style cat convertor, a Y pipe, & a small muffler for each tailpipe.

Another difference, the base '80 301 4 bbl T/A's (& other low horse Birds) did not have a large grommet in the cowl for the ESC harness to run through. The '80 W72 & LU8 equiiped Formulas & T/A's had that harness & small spark control box mounted behind a block off plate in front of the console. The base '80 301 4bbl T/As that I've had through here, when parted had 2.41 posi rears. All were AC cars. Beginning in the late 80's, I routinely bought early '70's & late '70's & '80's Esprits as a source for very nice Deluxe interior parts, solid straight doors, etc.

This car has the W73 option, once I get the PHS documentation I should know more. I have also requested the Vintage Vehicle Services info GM Canada documentation that will list all options that the car was ordered with along with the dealership the car was shipped to. This info is only available for Canadian built cars and US cars built in the US but shipped and sold at a Canadian dealer, once I have both I will post pics to show the different info.

W73 was the UPC code for Yellowbird option.
What differentiates your new find from most other Yellowbirds is being ordered with the 301W w Fisher tops & Rally Guage & Tach.

Clicking the grid style electric rear defroster required the addition of the HD Alt, which was of a new size case design. This 70 amp alt required its own style of PS & Alt brackets. . Another option that triggered the HD alt was the new for '80 models halogen headlights. In ordering my '80 SE Turbo, the zone office kicked the order back as i had ordered the both options & had not clicked off the HD alternator option.
