I have a 2002 F150 with SI/DO 50 Series Flowmasters with 3.5" tips....I love the sound, but I would like it louder. Plus I think the truck would look cleaner without the tips showing. Will it make much difference in my sound dumping the exhaust over the rear axle? I know it did on my Mustang, but it sets on the ground. Thanks for any help.

 

my exhaust used to dump behind the cab and yes it will make a differance. it will be deeper and truely a little bit louder. so if thats the sound you want i would say yes, dump them.

 

- Glad your running the 50's and that your running two of them - you prolly haven't hurt your torque at this point and could stand to off a little back pressure any way.

You have close to the perfect set up to get rid of /or gut one of your cats. I would gut the rears or replace with 2.5" pipe - don't touch the front cats ..

The part I loved the most was that GT sound I got after doing this - it's not really that loud , but when I take off from the light driving just a little above normal (little more gas than usual - it sounds absolutely killer !!

I'm running the 24" SISO Magnaflow now - before that , I was running a Flowbastid 50 series ( The short 50 , not the SUV type 50 series.) .

I went from the high 15's to 17.8 MPG and it's a hell of allot quicker of the line!! - Well it sounds quicker anyhoe...

You don't need four cats and can get rid of the rears without producing a check engine light. - You don't need a iliminator..

Do it , you'll be glad you did .

 

Edit...............
Sorry i see you have a 4.6 Edge and AF1.How does it run?bogg at start when ya nail it or lack of power at part throttle??
Jbrew knows what i am wondering I think it is 5.4 specific with that combo!!
