Best performance exhaust?
First off, my name is Jeremy and I recently got a 03 extended cab fx4. I am looking for the best performing exhaust NOT the loudest I can get it. Also what tunes would you all recommend? Troyer, 5 star? or who else? Thank you all for the input

Long tube headers, High flow cats, X pipe, mufflers of your choice. Straight through is the best option. Expect less than 20 hp gain. More like 10.
Troyer or 5 star will take care of you.

If it's stock (no hard parts in the engine modified or upgraded) and your cats aren't clogged, it breathes just fine. In fact, it's the way Ford Engineers designed it too. Surely we don't think we know more than they do??

But emissions do hold it back quite a bit, as well with the intake, Don't believe me take your stock truck go get a good exhaust, and intake and the smoothness of it will be much different as it goes through the rpm range, I know exhaust systems, but just figured I'd get an idea if the 5.4's like certain mufflers like the chebbies with the v-force. Did not mean to start a argument about exhaust, with how much it helps and don't help. sorry disregard this thread, Ill just get a nice straight through muffler. P.s. this truck will eventually have hard parts in the bottom end with the intention of a blower.

Will pretty much end up being a lightning once all said and done, have most the bottom end here, crank, rods, bearing kit, pistons, etc. just acquiring parts over this winter and next summer Ill be building it if I can manage to get everything I need over the winter.

Nice. If was building a 5.4 id definitely go with the 4 valve. Those are such great performance engines and as for the exhaust, i may be wrong, but i think borla attacks or whatev are the best for 5.4's

I would suggest some good lt headers of your choice then 3" to an x pipe then to two Maggie's Borlas roush anything with a straight through design then end them were you like. As for tunes I suggest mpt talk to franchimotorsports the best IMO he would give you some really good gains with custom tunes. And about the CIA I suggest the gotts mod and a good filter like amsoil ea filters I'm running one and the gotts mod and love it.
