Truck: 2006 FX4 5.4 3V.

Everything is stock on it right now and i need to replace one cat because of a code so i am going to put high-flows in it. Going with the Magnaflow 94106 high flow cats. As for the rest of the exhaust i cant decide on....

Either True duals with bullets or magnapacks and an xpipe or...

a Magnaflow or Dynomax SIDO muffler type.

either way the exit will be straight out the back. and piping is going to be 2.25".

only concerns i have is the sound. i want a deep throaty tone but i dont want to hear much of it on the highway or have it all popping like. i had a magnaflow catback and headers, race cats and race y pipe in my previous car and on the highway it was loud as hell no matter how fast i was going. i dont want that with my truck. i want to hear it when i accelerate and what not. i am trying to achieve it where if im on the highway doing like 65-85 its fairly quite so that i dont need to turn the radio up too loud to not hear the exhaust if that makes sense.

 

Go with a dynomax bullet for your muffler, then a DO for sure. Thats what I would do

 

i shoulda made it a poll....cost really isnt a problem because mommy is buying it for my bday present...haha gotta love moms.

thats one for SIDO

 

anyone know anything about the magnaflow 94109 cat? i went to autoshepherd cause their offering 20% off this weekend and they dont have the 94106, but they have the 94109

 

Go to performancepeddler.com and check the prices on their 94106s. Use promo code clubgp. I doubt you'll find cheaper prices anywhere even with the 20% off the other website is advertising.

 

thanks. btw do you have any vids of your exhaust setup?

how is the drone between 55-80 mph with your guys true dual setups compared to SIDO setups with high flow cats on either?

 

how much quieter would the 14" magnaflow be compared to the 11" used on true duals?

 

I LOVE how your only response to all of these threads is...Borla...hahaha

 

alright well ive got it figured out i think. only thing left is either 11" or 14" mufflers and what xpipe. i dont know anything about xpipes other then im doing 2.5in piping since the cats are 2.5

 

Magnaflow X pipes are perfect, but you can also get a cheaper one identical to it on ebay. I suggest 14" mufflers because you said in your first post that you didn't want much noise on the highway.

 

thats what i was probably going to go with was the 14". i was told about the ones on ebay but im skeptical about their durability and what not compared to an established company like magnaflow

 

^ As long as you get the stainless one, it is identical to the Magnaflow, and much cheaper. I would have no problem running it on my truck. Many other members here are running those X pipes with no problems.

 

Just placed the order with performancepeddler:

Magnaflow 94106 x 2
Magnaflow 35146 x 2
Magnaflow 11366 x 2
Magnaflow 10791

Hope to have it installed the day i get it or the day after. Hopefully by this weekend but im not sure how fast they normally ship. Anyone have an idea?
