I run nonPI heads on a 100K mile motor with a stock bottom end. I challange just about any of you (less a coupe that aided me in my setup) to gain 60% working with outdated technology.

I have a 2006 5.4l 3v. The piping is 2.5" so i decided to stick with that since I am not going to supercharge the truck.
Anyways, I used a Flowmaster 40 series that I had on my old 2000 gt mustang that I had laying around. It has a good sound and I am very pleased with it. The muffler is a 2.5" in and 2.5" out. All I needed to buy was a stainless tip to make it look nice. IMO this is the best route to go. It has a deep sound but not quite as loud since I didnt use 3" piping.

The school I'm from taught me forced induction vehicles, turbo or supercharger, needs a free flowing exhaust. Flowmaster mufflers are more restrictive, magnaflow mufflers aren't, but everyone goes to different schools, and I dislike tit for tat arguments.
I do think my magnaflow sounds better than a flowmaster, just an opinion.

I loved the sound of my flowmaster 40 series on my Dakota 4.7l. I had SIDO and it sounded great. With my new truck I will probably go Magnaflow unless I really don't like the sound. I don't want to lose any torque what so ever. I also doubt that anyone else will either. When you drive a truck that weighs around 6000 lbs, you shouldn't want to lose any torque either. It seems weird to me that some people can't feel a loss of 10 lb feet of torque but somehow claim to feel a HP/TQ increase from a different air filter like a K&N. To each his own.

Ill put my .02 in on this. I had both flows and maggie on my 02 never really did see a difference in them except for the rust. Here Jerzy they use a butt load of road salt, my flows lasted 2 years till the muffler rotted off. The flows did sound better than the maggie, as for the performance loss or gain ? didnt really look most of my drivin is highway. I eventually put a flow 40 on due to the maggie being tame on the sound. Now to do my 06 still in the air as to what im gonna put on!!!
