I'm about to get a 1999 F-150 4x4 ext. cab and i know i'm going to be putting exhaust intake and a few other things like a leveling kit on it. I was just wondering what would be the best exhaust for a 4.6 V8 since its a small V8. I like the loud and throaty sound. But i don't want it loud like no muff's or cats at all. Anybody got any info on the 4.6's. I'd love to hear anything about them but i'd like to know a good exhaust.

 

I plan on putting a flowmaster super 40 or 50 delta flow or 40 delta flow on my 97 4.6. I also heard cherry bomb glaspacks but they are LOOOUD. Flowmaster would be the best for your sound, will affect your low end torque a smidgen.

 

if i was you i would go with a magnaflow. ive had a flowmaster 40 on mine for a little over a year and im tired of the loss of torque. ive got mine dumped and it sounds great, but magnaflow is better when it comes to performance.

 

How bad is the torque loss? Like so you can't pulla trailer or do a simple burnout? Is it REALLY that bad?

 

Flowmaster's result in a loss of low end torque?? Magnaflow is a catback exhaust isn't it? Is it going to have the deep rumble to it?

 

its not that bad, but it is noticeable. its hard to take off. but it pulls really hard up top. although it is freakin loud. i guess you cant have loudness and performance. its either one or the other

 

I'm w/ buckles.I have true duels w/ 40s and it sounds great after about 2000rpm and it does pull harder up top.I definately noticed i lost down low even over the stock muffler which sucks.

 

So you gain high end torque? Interesting....

 

I can't say for sure but seat of pants felt like this,nutless off the line until you are over about 2500-3000rpm compared to stock exhaust.
Not what i'm after,i want tire scorchin take off
I have the 5.4
