i called an exhaust shop today, tryin to get it lined up for when i get home.

he said that i didnt really need hi- flow cats. and that the x pipe wont fit under my superduty. said he could run "true duals" from my crossover pipe.

550 bucks for the "cat back true duals" which include 2 flowmast 40 series mufflers, 1 on each side, and 2 7.5 inch dual walled polished SS tips. and it will be aluminized pipe.


i should be able to get the Pacesetter quick trip headers for around 300-400


any thoughts?

 

im not really sure about superduty exhausts...but how will he run true duals off the Y pipe?

7.5" tips?!?!?!?

 

7.5 inches long, 3 inches around. the pipe is goin to be 2.5 inches all the way around

 

this is a 5.4 right?

everything sounds good...im just still not sure how he is gonna run true duals off of a Y pipe. you need either a X or H pipe on there


and you MAY want to get bigger tips...
how are you gonna run the tips out?

 

First, get a plan YOU want, dont let a shop guy suggest something thats not as good to run as your original plan, just so it will be easier work for him.

Second, the stock Y pipe is restrictive to the left bank, even on the Super Dutys with the 3" in/out Y pipes. Run 2.5" pipes off from where the original Y was, then ti a 2.5" in/out Magnaflow X pipe, and 2.5" throughout.

If you like the tone of the 40s, go ahead with them, they do sound good on the Super Duty 5.4s.

I would run 18" long tips, whether straight out or 45'd, 18" length just look better on trucks, especially the Super Duty trucks with the higher rear end.

 

i dunno, i just said that ha can run it off my cros pipe that come stock, and that an x pipe wont fit, not enough room

 

That is correct!

 

Darren has that x-pipe on his f-150 it will fit on your superduty he means this one http://www.summitracing.com/parts/MPE-10791/ .

 

Theres a hell of alot of space underneith a Super Duty, a 12" wide X pipe will for sure fit. Take a tape measurer and go find out yourself. Your exhaust installer doesn't think you're trying to run a center body X pipe kit does he? Such as a Mustang X pipe? If thats what hes thinking, 1, he hasn't done alot of truck exhausts, 2, tell him it needs to run like the stock setup on the passenger side.

I wish I had the Magnaflow X pipe, I may save up for it and get one installed later after I change my mufflers to the new ones, but then I would need to get my left bank pipe re-bent, and if i'm going to do that, might as well convert to 2.25", so I dont know, debate debate debate

 

i hear ya darren..i wanna get bullets and get all my pipe ran 2.25

and go to the dark side..X-pipe

 

ill find a place wholl do the x pipe for sure. i supose SS over aluminized dont matter.

get the flomaster 40 series and some 7 inch long tips.

im definitly gettin 2.5 inch pipe.

are hi-flow cats all that?

 

X pipe and flows are nice...

 

It doesn't matter, but stainless will last much longer. It all depends on how unforgiving your winters are with road salt.

And the cats will increase the sound alot. You can always get the chugmasters on, then go and if its not loud enough order some cats and have them put in. Chambered mufflers dont break in so there will not be a break in time.

 

im stationed down in Tampa, FL, at MacDill AFB. NO WINTER. I love it. I suppose it cant hurt to wait on cats. I want to get my exhaust done somewhere before i get home from afghanistan, but i dont think its goin to happen.

cant find a damn shop who 1) will do the headers and exhaust, and 2) when ur deployed, your money must not seem like a viable source of income.

i dunno why

 

on my superduty van ,5.4 my ss dual exhaust with x pipe in 2.25" and mandrell bends - blows away the stock 3" siso setup our trucks came with-the reasons superduty 5.4's came with 3" siso vs 2.5" siso was to keep egts down as these were designed as work trucks-now u running 2.5" duals on a heavy *** superduty, will eliminate all your bottom end-but hey-it's ure truck
