Grand Marquis Exhaust!

[LilJuicedCoupe]

Anyone know the Diameter for a stock H-Pipe on a 1998 Grand Marquis???

Can't imagine it being more than 2-2.25".

Probably, due to the "luxury" theme of the car, 2" or smaller.

That said I don't know for sure.

2.125"

I know I should really remember this but its either 2.125" or 2.25"
