Will a 5.4L with no muffler on an 07 screw be too loud? with 3" or 2.5" pipe?

 

I have true duals with no muffler, and an x-pipe and i love the sound. Its not really all that loud unless you avccelerate really hard. If you go easy on the throttle its not loud at all. I have an 2005 with the 5.4, and my truck only has two catalytic converters...

 

You don't happen to have a sound clip do you?

 

I was disappointed in how it sounded actually. When I cut my old cat back off, figured hey, what the hell, let's see what I got here before bolting up a new one. I actually think the new exhaust on is louder in some ways. It must be the way it was angled or because I really didn't rev the hell outta it.

 

I don't know about the stock system minus the muffler, but true dual straight pipes are very loud. However, a dumped mufflerless exhaust might be too loud for some considering it's right underneath the cab.

 

Yeah but they have a sweet tone.

 

I stopped at the Quikie Mart this afternoon and there in the parking lot was I'd guess a '02 or so Silverado with quads on each side, in front of the rear wheels.. I waited until the guy came out and asked him what he was running.. he was in a hurry to leave but told me long tube headers, no cats, no mufflers.. he got in and fired it up and holy ****!!!!

Nothing I'd do on my truck, it was LOUD... but damn did it sound good!!

I can't imagine how it'd sound in the cab, can't hear yourself think probably..

 

if your running the 2 cats only a little loud, search it up on youtube.com, if your running the '05 & older 4 cat, hardly any different without a muffler still be too quiet.

 

I have a 2001 Screw 5.4. Last year cut out the mufflers, ran duals to the rear. It is throaty but not too loud. Does cause a few looks if you accelerate hard. Some places won't inspect it though.

 

apparently that AU education isn't working out for you. Its going to be loud as H***. Trust me it sounds cool for the first couple of months then youll hate it...that is if you can still hear anything.


PS ROLL TIDE

 

it's not as loud as you think it would be.

that's what i'm running and i honestly think if i were to put a single chamber flow or something compariable it would be louder than it is now.

plus with nitto muds it doesn't really matter b/c they're freaking LOUD

 

True duals on a pre '04 5.4 will be louder than on a '04 newer 5.4.

I love my true dual straight pipes!
