One of the sales men has been bragging on his 99 firehawk after check in out my SS. He finally brought i in yesterday and it all stock he bought it with 3 miles on it, it a six speed. Looking at the motor somthing didnt look right, It has corvette exhaust manifolds, Ive done about 10 sets of headers on ls1 so yes I know the difference. just wondering if anyone has info on this?
the vin number is
2G2FV22G1X2213344
THANKS

 

what did he say about them?

 

He thought his car had headers from the factory, you know how the vette ones look more like headers than manifolds.

 

Maybe it's an LS6 swap?

 

853 heads

 

`98-99 F-bodies have double wall sheetmetal exhaust manifolds (left one is same as Vette). These can be mistaken for shorty headers (I don't know how) but are actually more resrictive then the `00 up F-body cast iron manifolds.

 

Ok that might explain it, Ive never put headers on a 98-99 car that is what its go too be.

 

Interesting; I was unaware of this. Good knowledge!

 

I was expecting you to say it had a strange rear end.
