2011 Crown Victoria P71 Flowmaster 40’s Comparison

Completely Stock 2011 P71. Stock exhaust before Adding Flowmaster 40’s and deleting the rear cats.

Were they super 40s? Delta 40s or 40 series.. flowmaster has 3 options lol

Sounds awesome can’t imagine having straight pipes on these cars

[@dreteyete7305]

Straight pipes make it sound like a tractor unfortunately

[@Casual_Lifestyle]

Straight pipes on this car kind of suck. It just makes it unnecessarily loud and doesn’t have the smooth deep rumble that the flowmaster gives it

[@krownvikkhris3004]

Sounds awesome

I have an apt wed to put dual flowmaster 40's with 2.5 pipe after I hollow out the secondary cats tonight. I'm going from a single stock pipe. I'm excited. How's the power difference?

[@DCDAMAINMAN00]

So I need to do the update with the 2.5 tail pipes and 3.5 tips but I’ve noticed it’s more fun at higher rpms. Nothing significant, header back with no cats would probably be the best for power. But it’s a decent bump. It’s more just hearing that 4.6 with every push of the throttle. Let me know when it’s done! You’ll like the 40’s they compliment this vehicle well.

@@DCDAMAINMAN00 heck yeah man, I'll put up a post this week and show you

​@@HumCo34 how was the power difference bro? i have single exhaust now and want to do same set up not only for the gains but cause this is the best sounding set up for panthers

Did your check engine light came on

[@rxmarlo2303]

Bro we need another video of this!

[@lordofthemorphs4132]

You’re telling me! I miss this car sadly it was totaled leaving Atlanta Drunk drivers. I’d buy 5 more. It was an amazing sounding ride I didn’t even get to post a vid with custom piping

[@awk.z71]

How’s the drone on the highway?

[@DCDAMAINMAN00]

Honestly if going uphill and babying the throttle it’s semi bass like. But at speeds no drone. However I did just get custom 2.5” piping back and 3.5” tails. Now the tone is pretty perfect. And at road speeds its not too much. Stay tuned for update.

Still waiting for it to be ON
