Crown Vic to marauder

[lugovic]

how will I change a 2001 P71 to run and sound like a marauder

Sound... you'd need to buy the OEM mercury exhaust system, if there even is a difference between them.

not sure about the 50hp increase, I'd guess it's in the exhaust or maybe a ported head.

I'd say exhaust and intake will give you at least 50 hp.

Go buy a marauder and strip the guts out of it or go here and buy the right parts Blue Oval Chips Inc. - Welcome . Buying an intake and exhaust for a 4.6 unless its a turbo or super charger is not going to give you 50 hp maybe 20 hp tops.You will need an engine tuner( SCT tuner) different heads (performance Improved) PI / and matching intake PI. Bigger exhaust (2 1/2 front to mufflers and traction lock with 3.73 gears. Add a MZT intake kit from Blue Oval Chips Inc. - Welcome and you will run over a stock marauder

The power difference is because Marauders have the 32-valve 4.6 (like a Cobra) instead of the "normal" 4.6 every Vic is blessed with.

As for sound, I know the mufflers and exhaust tips are different, but I'm not sure about the rest of the system.
