Can anyone give me a ballpark price on a dual exhaust system with no difference in factory sound? I want to do it for the mileage and have chrome tips..magnaflow or flowmaster...thanks guys!

 

For a full Magnaflow cat-back your going to be paying anywhere between $350 and $450 or so dollars.

There are cheaper and more expensive brands, but Magnaflow seems to get the biggest nod' around here.

 

Im not sure if there is a dual exhaust set up that is as quiet as stock. i also like to add in my case when i added a dual exhaust kit it did really nothing for my mileage. Its a truck thought so just adding an exhaust to a near 6000 pound truck aint gonna do squat.

 

Yeah i understand, i knew it would only be a mile or two at most...how about horsepower...im just a warranty freakshow i dont wanna mess it up..i want to get an edge tuner for fuel economy but that would void my entire motor warranty..my truck is too new for that stuff...thought this might be a good way to gain a little power and a little horses...how is flowmaster???

 

Personally when i put my flowmaster on i did not feel the loss of power that people say flowmaster gives. On the other hand i did not feel any gain in power either the only thing that i noticed was the sound. My kit originally came with a 50 series suv and that was quiet but louder then stock but not loud enough for me. So i switched it out to a super 40 series. that made it louder still not too loud but little louder then then the 50 ended up really liking that. Then i had to cut my pipes off after i damaged one offroading or loading up the bed and now it is super 40 dumped under the bed and it is loud right now alittle bit too lound in the cab but after i added tips it went down alittle while cruising. All in all of those set ups didnt feel a diff in power out of those two mufflers. As far as my warranty knowledge goes the ford dealers i have asked said that usually a cat back for does not mind it is when you start messing before the cat. If you have anymore questions please feel free to ask. i am happy to help.

 

I did magna flow, love it wish it was louder but it sounds great. my milage went up from 12.6 to 13.9 dont know if that was my engine breaking in or what. but it on when the truck had 2500miles. was 800 for it

 

Buy a muffler and tips and take it to a shop and you will pay about $300.

 

I paid $140 for a complete duel exhaust setup. Tips, y pipe, piping. If you want to stay factory noise level, just y it after the OEM muffler! Looks and maybe a different sound...

With my duels, I definetly got an increase in acceleration, MPG and torque.

 

I think most people need to know these truck just will not be loud with a cat back exhaust. I dont know about 4.6 but im sure most 5.4 come with 4 cats. That is four little mufflers that are making these trucks so quite. Remove or cut them off and you will get the noise. I dont understand why they did this to the regular 150 but the lightnings had only 2.
