I have an 03 F-150 with a 4.6L and stock exhaust (for now). Eventually I want to do some exhaust upgrades (headers, dual exhaust, etc). I am just wondering what everyone reccommends on exhaust upgrades such as what brands/components are the best value and easiest to install. Would like to do a piece by piece upgrade so I am also wondering if I can change out the components piece by piece, or do I have swap out the entire exhaust at once?

 

here's a video of my old exhaust and new exhaust..sido

here's my '03 with magnaflow 15609 si/so 3" catback kit. If you're not looking to go too loud but still have a good toned sound, this might be what you're looking for.

Full exhaust might be a bit expensive depending on the parts your use and the shops labor costs.
I would recommend:
True dual exhaust
2.25 inch mandrel/smooth bent pipes
H/X-pipe
Hi-flow cats
Any brand off muffler that is straight through, Magnaflow, Dynomax Bullets, Borla, not Flowmaster or Cherry Bomb
Long tube headers, Pacesetter or what ever
3.5-4 inch tips exiting where ever.

 

hahah how was ur suspension punisher? did u enjoy sitting in a corner!?

 

Yeah I'm planning on getting some long tube headers and high flow cats, which is why I got the quieter muffler to begin with; I didn't want it extremely loud after the full exhaust install...if it ever happens that is

 

I did, I got to reflect on all the "bad words" that I keep saying to people that might have deserved it, and I got to read the rules again. Oodles of fun...

 

haaaaaa
back to the OP
dual dynomax bullets
2.5" piping
H pipe
3.5-4" tips out the rear both sides 45" degrees
dynatech long tube headers with 3/8" flanges
magnaflow high flow cats
volant CAI
