from everything i have seen- including the napa exhaust catalog,

the 1982 vin code H LG4 y pipe is one of a kind
one year only

is this true ?


can someone confirm ?


Vehicle:
1982 – 1982 Pontiac Firebird

Fits Engine – Chassis:

5.0L, V8, GAS, CARB, VIN "H" — Base
5.0L, V8, GAS, CARB, VIN "H" — S/E
5.0L, V8, GAS, CARB, VIN "H" — Trans Am


Fit Note:
Except High Output


Walker Y pipe #WK40498


1983-87 years vin H shows the Y pipe to be # 40497



so what is different about them ?

is it the curve to the cat converter, or the shape/style of connector to the converter ?



thanks

 

I would say that it's no different from any other third gen except for the factory TH-350. I have a th-350 in my car and it did not alter exhaust fitment at all.
