hello, i have a 07 F150 with the beast of a 5.4. im looking at buying LTs for it. question i have is should i get them with or without catts? ive looked at ARH and Dynatech and cant make up my mind which one would be the best one to go with

 

They sound wicked without cats, but then they stink up the whole area outside, and are ofcoarse an emissions fail.

 

My truck dose stink, when I'm sitting at a stop with my windows down Ill catch a whiff and it ain't so good, but its so worth it.

 

high flows will sound better than no cats, IMO

 

i agree, high flows sound great and flow nice. i would definetly do cats.

 

well looks like yall have made up my mind and now the new question i haev is which system is the most bang for the buck the american racing headers or dynatechs setup?

 

NO SIR!
I love the sound of mine with no cats after I put in the Magnaflow X pipe! I do have stock 06 manifolds though. I couldn't imagine the sound with LTs.

 

no sir? thats why i said In My Opinion.
IN MY OPINION, no cats sounds like garbage, and runs like it too

 

i love the sound of my high flows

 

That's a fact with the factory tune. If anyone thinks different, they need to repair that hole in their Marble bag.

Just curious, but does everyone fight with each other in the "Exhaust and Intake" forum.

 

its not fighting, its everyone speaking there opinions. sometimes it gets out of control though, i will have to agree on that.

 

Well, okay, - opinions is a little broad tho, whining works

 

 

I would recommend a set of hi-flows, just so you can stay legal. Last thing you want is a cop sitting behind you with a kean sense of smell.

oh, I have a sniper performance tune with no cats, but I didn't know it would sound any different with out a tune?
