thought you would like to hear them on a 2004 Pontiac
Gran Prix GT 3800 V6

Me likey!!!

Such a familiar, and yet still lovely sound. :s

Very nice.

thanks fellas, i posted this on another site, and they said they could not tell a difference between the stock and flowmasters

Goes to show you how much they know.

u know u may hear that crackle or poping sound under de-accerleration, well just to let u all know i downshifted it, with both the stock system and the flowmasters.. and i guess the other site wasnt aware of it.. or that it will do that when u down shift ur car to low gear, and thats why they said the stock system wasnt stock GM would not allow it lol but i am sure if u stand behind anysystem and accelerate hard then downshift to low gear to slow down most will crackle or pop..
