Sorry about the late comment. I am driving my second Grand Marquis. The one I have now is a 2000 GS. My previous Grand Marquis was a 2003 that an uninsured driver totalled.

your video convinced me to upgrade my exhaust myself, thanks!

Glad to see the installation great job man

1991 ltd crown victoria p72 351w

I have true dual 2.25 with 3 in roll tips and it sounds like a beast

Interesting video for sure my crown Vic is getting the H pipe and mufflers next week I am going to go with oem interceptor style.

Thanks bro was very helpfull im guessing another option i can do is go to junkyard and cut out a crown vic h pipe before the mufflers and the flanges should fit better?🤔

Def need to do something. Build that motor cuz yours is beat. My 08 crown roasts the posi rear end by mistake and keeps em spinning half way through second. My dad's 11 grand marquis torches the pass tire all the time. All stock.

i brought the car in september 2021 and the car was sitting in the driveway for 5 months and then i started to drive the car and it's making a noise like that when i press the gas i thought i was having a valve train noise but i don't think that's the problem. i changed the oil and now it's making that noise only when i press the gas. i change the spark plugs the air filter pcv valve change the motor oil and filter clean the throttle body and the mass air flow sensor i didn't change the fuel filter yet but i will so what can that noise be when i press the gas

I am currently building a 2004 mercury grand marquis. She has flowmaster super 40's on her,true duals,and marauder tips

I have an 04 grand marquis ultimate edition. Love it heated leather power everything. Was thinking of cutting the 2 catylic converters out and getting an h pipe

Anything needed to swap from a y pipe? Currently in the hunt to do so

It's time for a set of Stainless Works LT headers & some Magnaflows...

2011 cvpi, 91k mi 7700 idle hr and shes a highway ghost car, putting glasspacks on this weekend
