i want something legal so i have to keep the cat and mufflers on lol. i was thinking about getting a cut out but i heard its bad because not enough backpressure. what would you guys recommend for loud and performs strong

 

How much do you want to spend??
What size motor and what year truck?

 

2007 FX4 5.4. money isnt a big deal

 

Well the flowmaster is usually louder but some notice a loss of low end torque with them.I switched to Magnaflow myself from the loss with flows.
I myself would suggest the magnaflow over the flowmaster.I used to have flowmaster 40 series.Another good muffler is Borla or Dynomax bullets.
If all you want is loud get the flowmaster but you may notice a loss in low end torque depending on your set-up.The shorter the mufler the louder it will be.I think magnaflow has some really short ones out now???
Are you doing true duels or SI/DO??

 

i thought the f150s cant have true duel. i mean if so ill get the true. shorter route. but i dont want to loose performance. so you think i should go with magnaflwo right ? or check out the borla. you think i can run cut outs with the truedual or would it not make to much of a diffrence.

 

There are other members on here running true duels with the newer style f150's.You have to cut the Y-Pipe to make true duels.It would be louder and have a better tone if you do true duels.If you do true duels you should run an X-Pipe to balance it out.You could run cutouts in any exhaust system you wanted.The electric ones are nice.As long as you keep the pipe small you will not loose performance at all.What is reccomended is 2 1/4 inch pipe for true duels,do not go over!If you want loud take a look at what mufflers dynomax,borla,and magnaflow are making in the 2 1/4 inch.
I have the 14 inch rounds and i like the sound
Here is mine,i have a diff year truck as yours but i will try to find a thread i saw w/ true duels on a newer style

 

Here is the thread with true duels on a 06 f150

I would reccomend buying the magnaflow X-Pipe though,there are not many shops that can do that kind of work^^^^^^

 

the guy with the custon x-pipe said it wasnt to loud. maybe i can jsut put 2 cut outs when i want it to really roar after the x ? or should i just do it after the cats

 

It would not matter where you put the cut outs.
Why don't you just cut your muffler off and see how that sounds.That will give you a better idea of what it will sound like.
If you want to stay legal and have performance you have to use mufflers.Find the shortest one you can that is a straight through design.You could always have a y pipe put in and have an exh shop weld the duels up in a SI/DO.Also if you were to just take your factory exh off you could always put it back on to pass emissions.What i mean is have a shop make an exhaust that you could change back to stock easily if you wanted!

 

well ive taken my friends exhaust off and it sounds nice. but i heard if you leave it off to long its back for the valves and seals. so i didnt want to always have to cut outs open. i was thinking about getting a nice exhaust for the street and the electronic cut outs to show off.

 

it seems to me that you really want it to be loud. magnaflow is not going to be up to your standards if you want to keep the cats and mufflers and have it real loud. cut your cats and replace them with 2 magnaflow hi-flow cats (they are legal) and do a true dual setup like kevins using x-pipe and 2.25" pipes but with flowmaster 10 series mufflers (they are single chamber, no power loss) and it will friggin roar.

you said money isnt a huge issue, and this setup will give you what you want.

 

I agree with mSaLL150!!
I am also thinking the magnaflows will not be loud enough for you.I also agree on putting the high flow cats and flowmasters for you.
I think Josiah has the flowmaster 10 series??Sounds pretty bad a$$ IMO.

 

2 quick questions ive been looking for those parts. i cant find the highflow cat, neither can i find the 10. i found a 10 series but it was under racing exhaust. would that still be concidered legal on the street ?

 

go to www.troyerperformance.com you may be able to find the cats cheaper??The 10 series is a racing muffler and i am honestly not sure if it's legal.Definately look into it first.
