I just got my new 2003 F150 FX4, and i was thinking about a new air intake and dual exhaust, to up the horses and get better fuel efficiency. But I was wondering about how much this would cost me and what brands to go with.
Anyone have any suggestions, and what have you guys put on your trucks?


THanks

i got a 40 series flow on my truck with dual rear and chrome tips cost me $215 installed sounds good. I have a 4.6 v8

 

that sounds like what I am looking for, where did you get yours?
I heard some about the flowmaster 40 dont really understand the differences of them all. ????????? anyway nice truck man thanks for the adivce.


thanks
Jim

 

If i were you it would be a true dual magna flow setup or hell i might just do true dual straightpipes (no mufflers)
exhaust--anywhere from $200-800
intake-$220
computer chip--$250

 

I had flowmaster and hated it, mine droned in the cab, and took away hp/tq. I went wit ha true dual Magnaflow setup, and WOW the improvement in hp/tq was incredible, it helped my truck out as mush, maybe even more than the Superchip did. I would stay away from Flowmaster and just go magnaflow, + plus Magnaflow is Stainless Steel, and will last longer than my truck. Look in my gallery for pics.

 

No it wasn't a deal i just called around all the muffler places in town and the most was $260. I got the original 40 series not the delta flow, I don't have a whole lot of noise in the cab except at takeoff and on the highway at high speeds you can't hardly even tell it's there. It's loud but not unreal with the 4 cats, but thats the sound I wanted. As far as the horsepower and torque i don'tknow what it did or how it compares to the magnaflow cause im not into all that it drives and sounds good thats all that matters to me.

 

I got the Flowmaster 40 Delta series, SI/DO installed for $250 total. Nice mellow sound, truck is too new to tell if it made much of a difference. Sounds just like I wanted.

 

I had just asked about this a bit ago and got some good info.
